USB 3.0 vs USB 3.1: Which One Should You Choose?


Your specific needs and devices will determine the best choice between USB 3.0 and USB 3.1. Let me help you decide.USB 3.0’s 5 Gbps speed (about 500MB/s) works great for everyday tasks like connecting keyboards, mice, or simple external hard drives. But, you might want to invest in USB 3.1 Gen 2 with 10 Gbps capability for large files or high-speed storage devices.Here’s what you should know:

Choose USB 3.0 if you:

  • Use standard external HDDs (most max out at 200MB/s)
  • Connect simple peripherals
  • Want to save money on cables and devices
  • Don’t often transfer large files

Choose USB 3.1 if you:

  • Use high-speed SSDs
  • Work with 4K video files
  • Need 10 Gigabit Ethernet connections
  • Require faster charging capabilities

Actual performance is different from theoretical speeds. Users typically see only about a 10% speed increase with USB 3.1 compared to USB 3.0 in common scenarios.USB 3.1 Gen 2 devices provide faster data speeds, so ensure what you’re getting. Devices marked simply as USB 3.1 may default to Gen 1 and operate at USB 3.0 speeds. USB 3.0 offers enough speed for daily tasks. The extra cost of USB 3.1 Gen 2 devices makes sense only if you need the additional bandwidth for specialized equipment or frequently move very large files.

GPU docking station

Don’t throw away your old Gaming Graphics Card, buy a docking station to speed up your laptop!

Friends who often replace graphics cards know that it’s hard to deal with the old ones after upgrading. Throwing them in the trash takes up space, and selling them second-hand is painful. You might not know that a graphics card that’s outdated on a desktop can give a laptop a significant performance boost when installed.

GPU docking station

How can you put a graphics card in a laptop? This brings us to the laptop graphics card docking station, a magical device. My model is the Planit PL-LINK S-1, which allows you to connect a desktop graphics card to your laptop. When you get home, just connect your laptop, and the performance is instantly improved. When you’re on the go, unplug and you’re ready to leave.

This device is mainly simple and affordable. Inside the packaging, you’ll find, besides the docking station, a Thunderbolt cable, a screwdriver, and matching screws, as well as a fixing bracket.

The docking station has an open design with a power interface and a graphics card interface on the front. Notice that there’s a cover over the power interface that can be removed to accommodate an M.2 2280 solid-state drive, which seems to be very necessary for expanding the storage of Apple laptops.

docking station plate

Although Windows systems don’t need it, you can’t be without it.
On the side, there’s a power button, a network interface, and two Thunderbolt 3 ports. The Thunderbolt 3 port with the small computer supports 60W, while the other Thunderbolt 3 only supports up to 15W. If you have a thin and light laptop, you basically don’t need to consider additional power supply; this docking station can provide power.

The product assembly is very simple. Plug in the idle graphics card, place the power supply, and secure it with screws. There’s also a small bracket between the graphics card and the power supply, which holds the graphics card in place.

Connect the power supply and graphics card, and you’ll see that this open work platform looks very cool, with a full industrial cyberpunk style.

docking station connection with Thunderbolt4 cable

When you power up, the power supply and graphics card fans spin very fast. Once connected to the computer, the fan speed immediately slows down.

After connecting to the computer, the computer immediately recognizes the docking station and the graphics card. The docking station is plug-and-play, but the graphics card requires the installation of the latest drivers.
Using a detection tool to check the laptop, it has successfully installed the graphics card and drivers, and it is also recognized as the primary graphics card by default. Running a benchmark with Master Lu, it easily breaks through 1.28 million points, with a significant improvement in graphics performance. Of course, this is greatly related to the graphics card. I’m using an RTX 2070S here, which just makes up for the shortcomings. This docking station can support up to RTX 40 series graphics cards.

Now, let’s get down to work. I’m in the self-media industry, and I often work with photo editing, video editing, and live streaming. Don’t underestimate these tasks; they require a lot of CPU and GPU performance. When using a laptop, the preview starts to lag when there are a few more effects during editing. But with the external graphics card, previewing with six effects is also very smooth.
During the editing process, reversing video is very GPU-intensive. Without a dedicated graphics card, reversing video is the most troublesome, as it’s super slow. Now, with a dedicated graphics card, reversing video is very fast. A 30-second original video is reversed in just a few seconds, and the efficiency has greatly improved.

docking station GPU test

When reversing, I specifically checked the Task Manager, and the GPU usage was already over 90%. No wonder it was so slow without dedicated graphics card acceleration.

Next up is the live streaming experience. I use OBS for dual-camera live streaming here, and I also record the live content for later editing and republishing as videos. I tried it with a laptop before; it could handle dual-camera streaming, but adding recording caused significant frame drops, and it couldn’t maintain 25 frames for more than a few minutes. Now, with a dedicated graphics card, I’m not worried anymore; dual-camera live streaming plus recording is very stable.

I glanced at the Task Manager, and the GPU was utilized at over 90% throughout the process, but the noise from the power supply fan and the graphics card fan was very low, so much so that it wouldn’t even be picked up by the microphone. The fan control on the docking station is quite good, but the only thing I worry about is the dust issue with the open structure; should I DIY an acrylic transparent cover?

The processors in thin and light laptops are all hyped up, but the integrated graphics are what let them down. My laptop used to only run “CS:GO” at over 100 frames, and I knew my laptop’s capabilities, so I didn’t have high expectations. But now it’s different; I want to compete on the battlefield too. After connecting a graphics card to the laptop, the FPS easily reaches over 300 frames, smooth and silky.

Even games like “PlayerUnknown’s Battlegrounds” (PUBG), which I didn’t dare to play before, are now within reach. Before the docking station, my laptop could only manage 40-50 frames, with stuttering every jump and step, making it really unenjoyable. Now, I have a smooth experience with 140 frames.

No wonder I couldn’t play PUBG on my laptop before; even in the lobby doing nothing, the GPU usage reached 70%, which the laptop’s integrated graphics couldn’t handle.

I’ve calculated that this docking station can deliver about 90% of the graphics card’s performance, compared to the same version of Master Lu’s benchmark scores on a PC and a laptop. After all, this docking station is only a few hundred dollars; you can’t expect it to give 100%, right? The performance of a graphics card docking station mainly depends on the graphics card used. A high-end graphics card docking station might deliver about 95% of the graphics card’s performance, but the price difference is too high, and the extra money spent is really unnecessary.

After using this docking station for a while, I’ve found it to be really good, especially for those who already have a power supply and a graphics card. Spending a little money gives your laptop the performance of a desktop computer, which is quite cost-effective.

Micron: AI’s popularity cannot fill the “downcycle pit”.

Micron (MU.O) released its financial results for the first quarter of the fiscal year 2025 (ending November 2024) after the US stock market closed on the morning of December 19, 2024, Beijing time. The key points are as follows:

  1. Overall Performance: Revenue met expectations, but gross margin faced challenges. Micron’s total revenue for the first quarter of the fiscal year 2025 was $8.7 billion, an increase of 84.3% year-over-year, in line with market expectations ($8.72 billion). The revenue continued to rebound, driven by the company’s DRAM business growth. Micron achieved a net profit of $1.87 billion in the first quarter of the fiscal year 2025, with profits continuing to improve. Driven by the volume of HBM and the rise in storage product prices, both the company’s revenue and gross margin saw significant improvements, leading to a noticeable improvement in the company’s bottom line.
  2. Business Segment Performance: HBM is the main driver of performance. DRAM and NAND account for 99% of the company’s revenue, and HBM was the main driver of performance growth this quarter. Specifically, while both DRAM and NAND businesses saw significant year-over-year growth, there was a clear divergence on a quarter-over-quarter basis. DRAM business still grew by 20% quarter-over-quarter, while NAND business declined by 5%. This was mainly because DRAM continued to grow under the impetus of HBM, while the weakness in demand in traditional areas directly led to a quarter-over-quarter decline in NAND business.
  3. Outlook for the Next Quarter: Revenue for the second quarter of the fiscal year 2025 is expected to be between $7.9 billion and $8.1 billion (a quarter-over-quarter decline of 9%), below the market consensus expectation ($9 billion); the quarterly gross margin (GAAP) is expected to be between 36.5% and 38.5%, which is also a quarter-over-quarter decline and below the market consensus expectation (41.3%).

    Overall Performance: Revenue met expectations, but gross margin faced challenges.

  4. Overall view: The financial report for this quarter was somewhat satisfactory, but the guidance for the next quarter was disappointing. Micron’s revenue and gross margin continued to rebound this quarter, but the gross margin performance did not meet market expectations. Although HBM is still contributing to the company’s growth, the company was affected by traditional downstream markets such as mobile phones this quarter, leading to a decline in prices for some storage products, which in turn affected the gross margin performance. Looking at the business segments, the company’s DRAM business still saw a 20% quarter-over-quarter growth this quarter. Driven by HBM, the DRAM business continued to show an increase in both volume and price; however, the company’s NAND business declined by 5% quarter-over-quarter. This was mainly due to the impact of inventory adjustments in downstream sectors such as mobile phones, automobiles, and industry, with a slight quarter-over-quarter decline in both shipment volume and average price of related storage products. Compared to this quarter’s financial report, the company’s outlook for the next quarter is indeed “poor.” It not only interrupted the company’s continuous growth in revenue for seven consecutive quarters but also saw a decline of nearly $800 million quarter-over-quarter, and the gross margin may also decline quarter-over-quarter. This will undoubtedly add more concerns to the market: 1) Has the company’s current storage upcycle ended? 2) Is the company’s HBM business growth hindered? This directly led to a 16% decline in the company’s stock price after the market closed.
  5. Considering the industry and the company’s operating conditions, the decline in revenue for the next quarter is still mainly affected by sectors such as mobile phones and automobiles. From several perspectives: 1) The traditional areas are still in the inventory adjustment phase, and the company expects to gradually stabilize after the second half of the fiscal year 2025 (after March 2025 in the calendar year); 2) The company has further increased its total market size expectation for HBM next year to $30 billion (originally expected to be $25 billion), which shows the company’s confidence in the HBM business; 3) Recent rumors about NVIDIA adjusting the shipment structure of B200 and B300 will also affect the rhythm of Micron’s HBM to some extent. Overall, Micron’s current business includes both traditional storage demand and AI-related demands such as HBM. The company’s current performance is still mainly affected by traditional businesses, and the current downturn in traditional areas will directly affect the company’s subsequent business. As for the growth-oriented HBM business that the market is concerned about, although the current revenue share is still less than 10%, the company’s growth expectation for next year continues to be revised upwards. Therefore, the company’s performance will be under pressure in the first half of the fiscal year 2025, and with the destocking of downstream and the volume of HBM, the company’s performance is expected to see a significant improvement again in the second half of the year.

I. Overall Performance: Revenue meets expectations, but gross margin faces obstacles

1.1 Revenue

Micron’s total revenue for the first quarter of the fiscal year 2025 was $8.71 billion, a year-over-year increase of 84.3%, in line with market expectations ($8.72 billion). The revenue rebounded year-over-year, mainly driven by the price increase of the company’s storage products, with the average selling price of the company’s DRAM and NAND products both increasing by more than 60% year-over-year.

On a quarter-over-quarter basis, the company grew by 12.4%. Among them, the DRAM business still saw a 20% quarter-over-quarter growth this quarter, driven by HBM demand, while NAND saw a 5% quarter-over-quarter decline, mainly due to the impact of downstream inventory adjustments in the mobile phone, automotive, and industrial sectors.

Micron Technology Total Revenue

1.2 Gross Margin

Micron achieved a gross profit of $3.348 billion in the first quarter of the fiscal year 2025, and the company’s quarterly gross profit continued to rebound. The company’s gross margin for this quarter was 38.4%, lower than market expectations (39.3%). The increase in gross margin was mainly due to the rise in the average price of DRAM products and their proportion, but the weakness in some downstream sectors affected the extent of the rebound in gross margin. Although the company’s current inventory is $8.705 billion, a quarter-over-quarter decline of 1.9%. With the recovery in sales and the destocking of some downstream sectors, the company’s inventory turnover speed has increased, further adjusting the company’s inventory structure.

1.3 Operating Expenses

Micron’s operating expenses for the first quarter of the fiscal year 2025 were $1.176 billion, a year-over-year increase of 6.1%. With the growth in revenue, the company’s operating expense ratio for this quarter decreased to 13.5%. Looking at the breakdown of expenses: 1) Sales and administrative expenses: $288 million this quarter, a year-over-year increase of 9.5%. The sales and administrative expense ratio was 3.3%, a year-over-year decrease of 2.3 percentage points, with the decrease in proportion mainly due to the increase in revenue. Sales expenses are related to revenue performance, while administrative expenses are relatively rigid; 2) Research and development expenses: $888 million this quarter, a year-over-year increase of 5.1%. R&D expenses are the largest source of the company’s operating expenses, with the R&D expense ratio declining to 10.2% this quarter. As a technology company, the company places more emphasis on R&D capabilities, and the company’s R&D expenses are maintained at a relatively high level.

1.4 Net Profit

Micron achieved a net profit of $1.87 billion in the first quarter of the fiscal year 2025, in line with market expectations ($1.83 billion). The company’s profit growth this quarter was mainly due to the growth of the DRAM business and the improvement in gross margin. In this quarter, the company’s net profit margin was 21.5%, with a significant increase in profitability. Among them, the company’s operating profit for this quarter reached $2.1 billion, which has reached a relatively high position in the past cycle.

II. Business Segment Performance: HBM is the Main Driver of Performance
Micron Technology Segment Revenue
From the previous in-depth analysis by hugdiy.com on Micron in “Micron: Has the Winter for the Memory Chip Giant Ended?”, the company’s largest source of revenue is memory chips. According to the latest financial report, DRAM and NAND remain the most important sources of revenue for the company, accounting for 99% combined. Therefore, the changes in Micron’s business mainly depend on the performance of DRAM and NAND businesses.

2.1 DRAM

DRAM is the company’s largest source of revenue, accounting for more than 70%. In this quarter, the company’s DRAM business revenue increased to $6.39 billion, a year-over-year increase of 86.5%. Considering the performance of downstream sectors such as mobile phones and automobiles, Dolphin Jun believes that the $1 billion increase in DRAM business quarter-over-quarter is mainly driven by the demand for cloud server DRAM and the revenue growth of HBM. In terms of volume and price performance: the company’s DRAM business grew by 20% quarter-over-quarter this quarter, with shipments increasing by about 7% quarter-over-quarter, and prices also recovering by about 8%. The performance of both volume and price increase this quarter is mainly brought by the demand for cloud servers, while some products in traditional fields face price pressure. Taking DDR4 16G (1G16) 3200Mbps as an example, the product price has risen from a low of $2.89 in September 2023 to a high of $3.81 and then gradually fell to $3.09, and then rose again to $3.18 in December, while the average price in the company’s current fiscal quarter is clearly under pressure. Regarding the HBM field, which the market is concerned about, the products of the current industry leaders have all been updated to the latest HBM3E, among which SK Hynix and the company’s products have already been supplied to NVIDIA. According to YOLE, HBM products will be updated to the next generation of HBM by 2026. As for the market’s concerns about the company: 1) the sustainability of HBM growth; 2) competition from Samsung. Although there have been reports that Samsung has completed the core certification of NVIDIA, from the industry chain information, Samsung’s scale that can be mass-produced in the H200 product cycle is limited. As for the overall HBM total market size (TAM), the company has raised its expectation for 2025 to over $30 billion. Currently, the company’s share in HBM is only in the single digits, but in the future, the company is expected to increase its share to about 20%, which is comparable to its DRAM market share. As for the competition between GPUs and ASICs, both require HBM. As long as the overall market grows, the demand for HBM will continue to increase.

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.

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.

Capacity

The capacity of the SD card determines how many images or videos it can store. Capacity is crucial because game and trail cameras can record hundreds or even thousands of pictures. It also depends on how frequently they are activated.

  • For cameras that are used for shorter periods and only take a few pictures or videos daily, 16GB to 32GB are perfect.
  • 64GB–128GB: Larger capacity cards are advised for cameras set up for long-term monitoring. They are also for recording many pictures and videos.
  • 256GB or more: A high-capacity SDHC card for trail camera may be necessary if you’re shooting 4 K videos or taking large batches of pictures to ensure enough room.

Flash Format

The flash format affects speed and longevity, indicating how they are comparable.

  • SLC provides the fastest speeds and extended lifespan, but the cost is higher.
  • MLC is praised by most users for its cost-to-performance ratio, especially for game and trail cameras.
  • TLC is slower but more reasonably priced. There might be better options for cameras that take many HD pictures or videos.

Cost

In terms of cost, there is no universal solution. More expensive SD cards with larger capacities and higher speeds will cost more. Game and trail cameras don’t always need top-of-the-line SD cards. A more affordable Class 10 card is enough for stills and lower-resolution videos. Purchasing a UHS-1 or UHS-3 card is worthwhile. It is best if your game or trail camera needs to record high-definition video or take frequent snapshots. SDHC card for trail cameras is a top pick due to its shock resistance and waterproofness to withstand outdoor use.
