How to identify Counterfeit Micro SD cards?

Introduction

Fake Micro SD cards are flooding the market, leaving buyers disappointed with useless storage. They promise more than they can deliver, often resulting in lost money and data.
Fortunately, with the right knowledge and tools, like an SD card file size scam check, you can avoid these scams and ensure you’re getting the storage you paid for.

This write-up will walk you through spotting fake cards, testing their actual size, and steering clear of scams.

Overview of Micro SD Cards

Storage needs are everywhere, and Micro SD cards are the answer. These small cards help expand storage for smartphones, cameras, and gaming systems. Their affordability and compatibility make them an easy choice for many.
However, counterfeit versions are becoming more common as Micro SD cards become more popular. These fake cards closely imitate authentic ones, including their branding and packaging. Buying a counterfeit without paying attention can risk your data and funds. Learning to identify fakes is crucial to avoid these issues.

How to Spot the Difference Between Real and Fake Micro SD Cards?

Differentiating them takes effort, but knowing the right signs can save you. Here’s what to observe:

1. Printing

Look at the card’s logo, text, and overall design closely. Genuine Micro SD cards have clean, sharp printing with consistent fonts and colors. Counterfeit cards may have blurry logos, spelling mistakes, or inconsistent hues. Be sure to examine the packaging. Authentic brands maintain high-quality standards in both products and packaging.

2. Price

If a deal feels too good, it often is. Counterfeit cards are frequently sold at extremely low prices to draw in buyers. While discounts happen, unusually low prices should make you pause. Always compare with trusted sellers to spot any irregularities.

3. Speed

Running a speed test with proper software is the best way to test a Micro SD card. Fake cards can’t usually match the advertised speeds. For instance, a “Class 10” or “U3” card might perform slower than expected, revealing it’s fake.

4. Capacity

Some of such fake cards list false storage sizes. You must check actual size of SD card. For example, a 128GB card may only store 8GB before failing. You can use tools like H2testw or FakeFlashTest to check the true capacity of the card.


It’s vital to run this SD card file size scam check to confirm the card matches its claimed capacity and avoid data loss.

Paying attention to these factors will help you recognize real Micro SD cards and avoid storage scams.

The Risks of Using Counterfeit Micro SD Cards

While these SD cards might seem affordable, the risks can be significant. Here’s why relying on fake cards for storing data can be dangerous.

1. Data Loss

Fake Micro SD cards carry the risk of data loss. These counterfeit cards often fail to store data properly, resulting in file corruption or complete loss. They might appear to have enough space, but once large amounts of data are saved, files can vanish, or the card may crash. Sadly, recovering lost data is almost impossible.

2. Money Loss

Fake Micro SD cards seem tempting because of their low prices, but they come with hidden costs. When they stop working, you lose both the product and your data. If you use them for important tasks, replacing the lost files or repairing devices can become an expensive problem.

3. Time Loss

In any professional setting, time is key. Fake cards can delay processes due to transfer issues or slow processing. This can result in missed deadlines, lost business, and interruptions. What should be a quick task can waste hours.

4. Project Failure

Creative professionals working with videography or photography know the importance of reliable storage. Using these cards can be disastrous. A failed card could cause hours of footage to vanish, delaying or ruining a project. This not only affects your work but also your reputation.

When you realize the risks, it becomes clear that using genuine, reliable Micro SD cards is essential. Fake cards can lead to problems like frustration, loss of money, and failure in various aspects of life.

How to Avoid Ordering Fake Micro SD Cards?

The best way to avoid the risks of these cards is to be proactive in your purchasing process. Purchase from trusted retailers, test samples, watch pricing, and inspect the card closely. This effort can save you from long-term issues.

1. Purchase from Reputed Suppliers

For authentic Micro SD cards, always buy from trusted, well-known retailers or the manufacturer. Reputable suppliers focus on authenticity and customer satisfaction, making counterfeits less likely. Avoid third-party sellers on eBay or Amazon, where fake cards are often offered at lower prices. Stick to authorized dealers or official sites for genuine products.

2. Sample Testing

If you’re planning a bulk purchase of Micro SD cards, test a few first. Most suppliers let you check them for quality. You can spot fake cards before committing to a full purchase by running tests for speed and capacity.

3. Reasonable Pricing

A Micro SD card that costs much less than the market price is a red flag. Counterfeit cards are often sold at a steep discount to trick buyers. Discounts happen, but prices that seem too cheap are a warning sign. Always compare prices from trusted retailers to be safe.

4. Check the Appearance

When you receive a Micro SD card, inspect it and its packaging closely. Genuine cards feature sharp logos, clear printing, and consistent fonts. Watch for blurry text, misspelled words, or any damage to the packaging. Counterfeit cards often have inconsistencies in logo design or color. A careful check can prevent you from getting a fake.

Conclusion

While counterfeit Micro SD cards might seem like a deal, the risks are high. You could lose data, waste money, and face other problems. Counterfeit cards often fail to deliver on their promised storage or speed.

Look for red flags like oddly low prices, poor printing, or inconsistencies in performance. Always purchase from trusted vendors, test cards when you can, and avoid deals that seem too good to be true. An extra caution can help you get the real thing, keeping your data secure.

So, understanding what to prioritize is key if you’re looking for the best SD cards for trail cameras or SD cards for game cameras. Let’s explore everything that matters most.

Trail Camera micro sd cards

Difference Between Game Camera and Trail Camera

The terms “game camera” and “trail camera” get mixed up a lot, though they are designed for specific uses. They’re both meant for outdoor settings, typically by hunters or those studying wildlife, but their goals can differ.

Game Camera

A game camera helps hunters monitor wildlife. It helps track animal behavior and movements by providing high-quality footage. These cameras are set up in areas where hunters want to learn about animal movements. Many have useful features like long battery life, better low-light performance, and wireless transfer capabilities.

Trail Camera

Their broader features than game cameras include wider lenses and improved durability for harsh weather. Some are also used for outdoor security or adventure tracking.

How to Select the Best SD Card for Game Cameras and Trail Cameras?

You need to consider different aspects that are crucial to you when you are looking for the best SD Card for a trail camera or game camera. Cellular connectivity, sensitivity range, trigger speed, and quality are the most important factors to consider when selecting a new SD card for trail camera.

Speed

Quantified by Class or UHS (Ultra High Speed) ratings, the SD card’s speed is crucial if your camera produces high-quality images and video. The majority of game cameras and trail cameras are compatible with Class 10, a standard for contemporary SD cards with a minimum write speed of 10 MB/s. Compared to Class 10, UHS-1 offers faster speeds of up to 104 MB/s. UHS-3 cards work best with cameras that capture 4K or high-definition footage.

what does nm mean in flash chips?

In today’s mainstream CPUs or NAND Flash, there are often hundreds of billions of transistors packaged inside. What exactly are these transistors? And what is their construction like? Broadly speaking, transistors are mainly divided into two types: BJT bipolar junction transistors and FET field-effect transistors. Currently, most of the transistors packaged in chips are MOSFETs, which are a type of field-effect transistor. This is its circuit symbol.When we apply a high voltage to its gate, the drain and source can conduct, but when we apply a low voltage, it will cut off, which is equivalent to being disconnected.

how is mosfet work in chips
Next, let’s look at its construction. This is an early planar transistor, mainly used for chip processes ranging from 10,000 nanometers to 22 nanometers. Now, let’s talk about how it works. These are its drain and source, which are essentially two pieces of n-type semiconductors with a high concentration of free electrons. In the middle is the substrate, which is essentially a p-type semiconductor with a low concentration of free electrons. If we connect the drain and source with electricity at this time, it cannot conduct.Because although the p-type substrate has a certain amount of electrons, the concentration is extremely low and far from enough to build an effective electrical conduction path between the source and drain. At this time, people added an insulating layer on the substrate, and then added a highly conductive metal plate on the substrate as the gate. In this way, when we apply voltage to the gate, the electrons in the p-type substrate will be attracted to the vicinity of the insulator, and the concentration of free electrons at the junction of the substrate and the insulator will become higher. At this time, when we connect the source and drain with electricity again, it will conduct. Because an effective electrical conduction path has been built between the source and drain.

For this planar transistor, the chip process refers to the length of its gate. For example, if its gate length is 180 nanometers, then it is a chip with a 180-nanometer process. However, when the chip process is reduced to 22 nanometers and below, due to the short-channel effect, the distance between the drain and the source is too short, and the drain electric field will interfere with the gate’s control over the channel, leading to an increase in leakage current. This invisibly increases power consumption, and the channel is difficult to shorten further.

Therefore, when entering the era of three-dimensional transistors, such as FinFET and GAAAFET transistors, the “nanometers” in chip manufacturing no longer refer to the gate length of the transistor. The term “nanometers” is more of a marketing term. For example, in a 3-nanometer process chip, the gate length of its transistors may be between 15 and 20 nanometers. You can see the difference in construction between them and conventional MOSFETs. The conventional construction direction is horizontal, while the construction direction of three-dimensional transistors is vertical. Next, let’s look at the construction of FinFET and GAAAFET transistors. First, let’s talk about FinFET. The FinFET transistor was invented by Professor Hu Shengming from Taiwan Province and is mainly used in the 22-3 nanometer process nodes. Because its channel is protruding and looks like a fish fin, it is called a fin transistor. This type of transistor has solved the short-channel effect well, but it is still essentially a MOSFET. The working principle of the fin transistor is similar to that of the planar transistor. The bottom is a large substrate, which is a p-type semiconductor. Its two sides are covered with two insulators, and above are two N-type semiconductors as the source and drain. Then, the three sides are surrounded by insulators, and the top is a highly conductive metal as the gate. When we electrify the gate, all three sides of the p-type substrate will be attracted by the electric field, providing better gate control.

Despite the improved gate control provided by three-dimensional structures, for extremely small sizes, such as below three nanometers, electric field interference and leakage current are still hard to avoid. Therefore, the ingenious humans invented the GAAAFET transistor, also known as the gate-all-around transistor, which is mainly used below three nanometers. You can take a look at its structure: the bottom layer is the substrate, followed by two layers of oxide, which can be seen as the tray of the transistor. Above that are three very thin nano channels, composed of n-type and p-type semiconductors. Then, a layer of oxide (insulating material) is wrapped around the four sides of its p-area, and a piece of highly conductive metal is added as the gate. Compared to the three-sided gate of FinFET, GAAAFET achieves a 360-degree gate wrap, hence the name gate-all-around transistor. This further strengthens the gate control capability, and these three channels essentially belong to one transistor. Devices like Central Processing Units (CPUs) and Graphics Processing Units (GPUs) often need to handle large amounts of data and complex computational tasks, which requires the transistors that make them up to have a strong current driving capability for rapid signal transmission and processing.

GAAFET transistors, due to their multi-channel design, can significantly enhance the driving capability of the transistor. Without significantly reducing the gate length, FinFET and GAAAFET transistors increase gate control by wrapping around the gate from multiple angles, reducing the unit area occupied by the transistor. This allows for more transistors to be integrated within the same area, effectively shortening the gate length. This is my interpretation of these three types of transistors, and I hope it helps you understand them better.

What is NAND Flash Memory and How it works

What is Flash memory

Flash memory is the core of storage for solid-state drives, USB drives, and memory cards. It can typically store hundreds of gigabytes of data in a space the size of a fingernail. It is an invention that is as renowned as the Nobel Prize. Flash memory storage relies on floating-gate MOSFETs. Before discussing floating-gate transistors, let’s briefly introduce MOSFETs, as floating-gate transistors are an improvement based on MOSFETs. The principle of MOSFETs is quite understandable. These three black areas are metal conductors, and the n-type semiconductors on both sides contain many free electrons. If we apply electricity to the n-type semiconductors, they can conduct, acting like a piece of wire. The p-type semiconductor in the middle has very few free electrons, so when we apply voltage to the base, it is cut off because the concentration of free electrons in the p-region is too low to form a conductive channel.
memory card and usb drive SSD
To make the MOSFET conduct, we can apply a voltage to its gate, attracting the electrons in the p-region towards the gate.
Because there is a layer of silicon dioxide between the gate and the p-region, which is insulating, free electrons cannot pass through under normal circumstances. So, when we apply voltage to the gate, the free electrons in the p-region gather near the insulating layer, forming a conductive channel, and thus it conducts.

Floating-gate mosfets

However, when we remove the gate voltage, the electrons gathered near the insulating layer disperse, and no conductive channel is formed. Since no current flows, the MOSFET is cut off at this time. This is the circuit symbol for a MOSFET. Simply put, when we apply a high voltage to its gate, it will conduct, and when we apply a low voltage, it will be cut off.

Floating-gate MOSFETs are very similar to MOSFETs, except for an additional bar in the middle, which represents the floating gate. Since they are both MOSFETs, their structures are similar. A floating-gate MOSFET has an additional conductive floating gate layer added to the oxide layer of a MOSFET, allowing it to store information. Let’s talk about how to write information first. If we apply a high voltage of 20 volts to the gate and 0 volts to the substrate, some of the free electrons in the channel will be attracted to the floating gate layer. Even if we then power off, the free electrons will still be stored in the floating gate layer because the floating gate layer is insulated by silicon dioxide layers above and below, and the free electrons simply cannot escape. This is how information is stored, with the charge stored being considered a logical zero.There is also a question about how electrons can pass through the tunnel oxide layer, which is also an insulating layer. This is actually due to the tunneling effect. For example, a silicon dioxide oxide layer is normally insulating, but if we apply a voltage large enough, greater than 10 million volts per centimeter, electrons can pass through this insulating layer. This is the tunneling effect. When we apply a 20V high voltage to the gate, due to the thinness of the tunnel layer and the high voltage per unit thickness it withstands, electrons from the p-region are attracted. It is important to note that at this time, do not apply voltage to the drain, or a sub-threshold conduction channel will form, and electrons will flow in this manner, which would hinder the occurrence of the tunneling effect.

When we apply a low voltage of 10 volts, electrons cannot pass through the insulating layer, just like a conventional MOSFET. Understanding the principle of flash memory writing makes it easy to understand its parameter principle. We just need to apply a high voltage of 20 volts to its substrate while applying 0V to the gate. At this time, the free electrons imprisoned in the floating gate layer will be attracted out, and the data will be erased. Erasing is writing a logical one. Storing one bit of information requires only one floating-gate MOSFET. To store 1GB of information, at least 8.5 billion floating-gate transistors are needed. How do we control so much information?

How does nand flash work​

You can see this is a flash memory block that can store 16 bits of information. The middle ones are floating-gate MOSFETs that store information. The top and bottom ones are conventional MOSFETs that play a controlling role here. The horizontal ones are its word lines, connecting the gates of these rows of MOSFETs. The vertical ones are its bit lines. Its writing minimum unit is a page. A page is a row. When we want to write, we first need to erase all the data in this entire block, which means releasing the electrons stored in the floating gate layer, and all storage units will become logical ones.

How do we write by page? For example, if we want to write the page “word1,” we need to apply 20 volts of high voltage to the radiation MOSFETs of this page, and other MOSFETs should not be given high voltage. In this way, only the data of this page with 20 volts of high voltage can possibly be written. If we want to store a charge and write 0, we write 0 to its corresponding bit line, so free electrons will be attracted to the floating gate layer, and this bit will be written as logical 0. If we want to write 1, it’s very simple because we need to erase before writing, and after erasing, the data is all 1. We just need to keep the data unchanged. For example, if we want to write 1 to this bit, we write a high voltage to its bit line, which will hinder the tunneling effect. So, free electrons will not be captured by the floating gate layer, and it will remain logical one unchanged. The minimum unit for writing data is a page of data, and the minimum unit for erasing data is to erase the entire block. We need to give all of them zero volts and then apply a high voltage of 20 volts to the substrate.

You might be curious why the minimum unit for erasing is an entire block of data. Look at its cross-section, and you will understand. All storage units of this flash memory share a substrate. Just by applying a high voltage of 20 volts to the substrate, the operation of erasing the entire block of data can be completed. The minimum writing unit is a page because the gates of the MOSFETs on this page are connected together. This block of data can store 16 bits of data. One page is 4 bits of data, and a real flash memory page has 65,536 storage units per block. There are 512 pages in the data, so a block of flash memory data can store more than 33 million data points. This is what we call 4MB of data. Even if we want to write one bit of data, we also have to erase these more than 33 million bits of data before we can write.A block of data is 4MB, and to make up 1GB, you would need 256 flash memory blocks. The packaging size of the chip is standardized. To package enough storage units within the chip, the storage units must be made small enough to fit more of them in. However, as they are downsized, many issues arise. For instance, the tunnel oxide layer also becomes thinner. Due to the process of erasing and writing, electrons need to pass through the oxide layer repeatedly. If this happens too many times, the tunnel oxide layer can become damaged and fail to block the electrons, leading to data not being well preserved.

What is 3d nand flash​


To address this issue, humans invented 3D NAND flash, which eliminates the need to increase the number of storage units by downsizing MOSFETs. This is a 4-layer flash that stands the conductive channels upright, with horizontal pages of data. This area represents a block of data, and the middle contains all its storage units. So far, 3D NAND flash memory has achieved a stack of 232 layers, with a storage density of about 15GB per square millimeter. By using 3D stacking, not only can the unit capacity be increased several times, but also, because of the three-dimensional technology, the size of the storage units does not need to be reduced. As a result, the number of write-erase cycles is increased by more than tenfold. This is my understanding of flash memory technology, and I hope it helps your comprehension.

STM32 Demo Board: Getting Started and Advanced Preparation

Essentials for Beginners

The development board may look simple, but many people are discouraged at the step of how to use it. Today, I’m here to teach you how to solve the problems of getting started with single-board computers (SBCs), taking the Orange Pi Zero 3 as an example. How many steps are generally needed to use an Orange Pi? First, prepare a USB Type-C power cable, a charger with at least 5V 2A , a memory card with a capacity of at least 8GB, and a Micro HDMI cable to connect to a monitor or TV to display information from the development board. Some Demo Boards may have DP or mini HDMI interfaces, or standard HDMI interfaces, and you will need to purchase the corresponding cables to match your development board.

custom Micro SDHC card 16GB
If your monitor doesn’t have a DP interface, you can opt for a DP-to-HDMI cable. However, as of now, there are still few Demo Boards without an HDMI interface. We also need to prepare a keyboard, and if you’re using a desktop like Windows, you’ll also need a mouse. If your Demo Board doesn’t have WiFi or Bluetooth, you’ll need to provide an Ethernet cable and access to the internet. Finally, you’ll need a working computer with a USB port. If your Demo Board has onboard eMMC, you won’t need to prepare a TF card. If your development board also has an M.2 SSD interface and you happen to want to use an SSD, you’ll also need to prepare an SSD.

After preparing all this hardware, the next step is to install the system. Installing a system on a development board is simpler than on a computer. First, find the official website of the development board and download the system you want to use onto your computer. Then you can proceed to install the system. There are several installation methods, which differ depending on which storage medium you want to install the system on, such as a memory card, eMMC, or SSD. Installing on a memory card is the simplest.

Here, pay attention to the protocols and sizes of the SSDs supported by the development board. There are two protocols: M.2 SATA SSD interfaces and NVMe SSD interfaces. In terms of size, they vary based on length with M.2 2230, 2242, and 2280 being the main sizes. You need to choose the SSD based on the protocols and slots provided by the development board.

Flashing the system to the SSD is also done using the Ralink development tools, with the difference being the configuration file; just select PCI and the system installation is complete.

Once the hardware and software are ready, plug in the HDMI and power cables and wait for the system to boot. Note that some Demo Boards have a switch, which could be a selection switch or a push-button switch, so you should refer to the documentation for operation. Generally, the system will start automatically when powered, and if it doesn’t start automatically, check if the switch hasn’t been pressed.

Professional Player Essentials

Some commonly used tools in electronic design, which can also be considered essential, start with soldering. First is the soldering iron, which comes in temperature-controlled and adjustable temperature models. A temperature-controlled soldering iron is similar to this type where you plug it in and it directly reaches a fixed temperature.

The higher the wattage, the faster it heats up. An adjustable temperature soldering iron is similar to this type, generally adjustable between 200 to 500 degrees, because some chips have requirements for soldering temperature and cannot withstand high temperatures, so this adjustable temperature soldering iron has a broader range of applications. When using a soldering iron, you need a soldering iron stand, which comes in various types and can be chosen based on personal preference.

Soldering Iron

When using a soldering iron, you need to frequently clean the tip, which is where the soldering sponge comes in, similar to the one in the picture. Then there’s solder, which comes in leaded and lead-free varieties, with different tin content and wire gauges. I personally often use 63/37 tin with a 0.6mm diameter.

There’s also flux in the form of solder paste or rosin, solder paste is similar to the one in the picture. Rosin is similar to this type of desoldering pump. When soldering and needing to remove some solder, a desoldering pump is needed, which looks like the one in the picture. Then there’s the solder wick, which is this type of perforated board, but it’s basically disposable, and after soldering, it’s hard to clean and reuse.

Breadboard

A breadboard is a type of board where you can insert components and perform some debugging and testing.

Dupont Wire

Dupont wires are used to connect two endpoints of a test circuit, generally divided into male and female ends, with the female end being this type with holes and pins. Choose according to your needs, and the male end looks like this, which is also a commonly used small tool in testing circuits. You can insert Dupont wires or their corresponding sockets, and this is the socket corresponding to the pins.

Tinned Wire

Then there’s tinned wire, also known as enameled wire, which comes in different thicknesses and lengths, and is also commonly used in testing to connect two solder points.

Others

Tweezers are used as conductors for adding small precision components, and small surface-mount resistors and capacitors are commonly used. Flush cutters are used for trimming, similar to this type, generally for cutting the leads of some soft components. To strip the outer skin of wires, you need wire strippers, which are also commonly used.

A multimeter is also the most commonly used tool for measuring current, voltage, resistance, capacitance, and continuity, which can be said to be the most commonly used tool in electronic design.

Conclusion

Then there are some tools that are not commonly used at the beginning of electronic design, but can be added later when needed, such as hot air guns, needle-nose pliers, screwdrivers, some fixtures, heat shrink tubes, regulated power supplies, oscilloscopes, and logic analyzers. Basic electronic design may not need these for the time being.

This article introduces how to choose and use STM32. It is hoped that through the introduction in this article, beginners can understand the basic concepts and entry guide of STM32 for subsequent learning and application. If you don’t understand embedded systems, come to me. Thank you, everyone.

MLC Vs TLC, Is MLC Better Than TLC for SD Card?

MLC Vs TLC NAND Flash Memory Card

MLC Vs TLC,An SD card’s cost and storage are only part of the story. For essential data, understanding the NAND flash type—MLC or TLC—matters. These types affect speed and durability. This article explores them, helping you make the best choice.

MLC Vs TLC, Overview of MLC and TLC

In SD storage, the choice between MLC Vs TLC NAND flash impacts your card’s performance, lifespan, and cost. These flash types represent different data storage approaches, offering options tailored to specific user needs.

MLC 10000 write cycles, TLC 3000 to 5000 write cycles.

What is a Multi-Level Cell?

MLC, storing two bits per cell, offers a balance of speed and durability. This type works well for users needing moderate performance without a premium price.

Why MLC is Beneficial for SD Cards?

  • Enhanced Durability: With fewer bits per cell, MLC wears down more slowly, making it ideal for those needing consistent performance.
  • Affordable Quality: Though pricier than TLC, MLC is more affordable than high-end options, striking a nice balance for value-focused users.
  • Fast Performance: MLC’s read and write speeds often outperform TLC, supporting faster data handling for larger files.

MLC’s Downsides

  • Higher Cost: MLC isn’t as budget-friendly as TLC, which may not suit everyone.
  • Moderate Storage Density: MLC’s lower bit density per cell limits storage capacity compared to TLC.

Understanding TLC NAND Flash

TLC stores three bits per cell, making it an economical choice with high storage potential. It’s renowned for consumers looking for substantial storage without needing professional-grade speed.

Advantages of TLC in SD Cards

  • Budget-Friendly: TLC’s lower production cost leads to cheaper SD cards, ideal for everyday users.
  • Larger Capacity: Higher bit density per cell means more storage, perfect for extensive multimedia files.
  • Acceptable Speed for General Tasks: While slower than MLC, TLC’s performance is sufficient for daily use.

TLC’s Drawbacks

  • Shorter Lifespan: Increased density causes more wear, affecting durability in heavy-use settings.
  • Lower Speed: TLC’s read/write speeds can be slower, noticeable for data-heavy tasks.
  • Potential Data Loss: Storing three bits per cell can lead to gradual data degradation, though error correction assists in maintaining data integrity.

MLC vs TLC NAND Flash Memory: Key Differences Between

MLC Vs TLC cards differ mainly in cost, lifespan, and speed. Let’s break it down for clarity.

Cost: Affordability and Value

TLC cards are usually more affordable than MLC cards. This is because TLC can store three bits of data per cell, which allows for higher storage density and lower production costs. As a result, you’ll often find TLC cards offer more storage for a lower price.
In contrast, MLC cards store only two bits per cell, which requires more cells for the same amount of data. This raises the cost, making MLC cards more expensive. But this higher price brings better performance and durability. If you need a cost-effective option for light use, TLC is good, but MLC is a better choice for long-term performance.

Life Cycle: Durability

In terms of durability, MLC generally outlasts TLC. MLC cards wear less over time since they store fewer bits per cell. TLC cards, on the other hand, put more strain on their cells due to storing three bits per cell, which can lead to quicker wear. If you’re using the card for tasks like photography or video recording, where you write data frequently, MLC is more durable. TLC works just fine for lighter use, but MLC is the better option for long-term, heavy use.

Speed and Performance: Efficiency and Reliability

When it comes to speed, MLC cards are faster than TLC cards. Since MLC stores fewer bits per cell, it can quickly read and write data. This is especially useful for high-demand tasks like transferring large files or recording video. MLC cards maintain consistent speed even when the workload increases. While fine for everyday tasks, TLC cards might slow down during intensive use, especially for 4K video recording. If you’re working with demanding applications, MLC is the better choice for speed.

Relationship Between NAND Flash Types and Memory Cards

In SD and MicroSD cards, NAND flash types—categorized as SLC, MLC, and TLC—shape factors like speed, durability, and storage. Each type has specific advantages designed for different demands.

Impact on Speed and Performance

  • SLC (Single-Level Cell): Fastest and most durable, ideal for high-performance applications like servers or professional cameras, but expensive.
  • MLC (Multi-Level Cell): Balanced speed and cost, good for consumer electronics like DSLRs and high-end smartphones. It’s slower than SLC but offers a good compromise for most users.
  • TLC (Triple-Level Cell): Slowest, best for everyday use like storing photos or music. It’s affordable and provides large storage, but performance can degrade under heavy use.

For example, if recording a 4K video, MLC or SLC would be ideal, while TLC works for lighter tasks.

SLC VS MLC VS TLC Impact on Capacity

  • SLC: Limited capacity but offers the best performance and durability.
  • MLC: Offers a balance between storage and performance, typically found in mid-range devices.
  • TLC: High storage density, making it the most affordable option, but with slower performance, especially in large capacities.

TLC cards provide more space at a lower price but may perform slower than MLC, which strikes a balance.

Future Developments in NAND Flash Technology and Implications for SD Cards

The NAND flash field is evolving rapidly, with QLC improving storage and performance. As MLC and TLC are replaced by QLC, SD cards show clear advantages in cost, capacity, and efficiency.

QLC: More Storage at a Lower Cost

QLC technology, storing four data bits per cell, provides higher capacity for SD cards. This is a win for consumers, especially those handling large files like videos or photos, as it means lower prices per storage unit. However, QLC’s design does lead to faster wear, making it less ideal for frequent heavy use.

Looking Ahead: PLC in Development

With QLC mainstream, research is now focused on PLC (Penta-Level Cell), which could hold even more data. While still experimental, PLC may soon offer larger capacities and lower costs.

Lower Costs for Consumers

Each advancement in NAND technology leads to more affordable SD cards, which is good news for anyone with high data needs.

Enhanced Controllers to Boost Performance

Newer controllers and firmware updates are designed to improve the performance of high-density NAND types like QLC, helping them run faster and last longer.

Different Options for Different Needs

Consumers will see more tailored choices in SD cards. SLC remains best for durability, while QLC and PLC will serve those looking for more affordable storage.
