The article introduce that there is a performance differences of the memory cards at different class or even same class by testing the performance of Class 10 products under USB 2.0 and USB 3.0 interfaces. Different classes are suitable for different consumers. Performance, capacity and price should be considered when choosing them. In addition, UHS-1 products can provide more performance for users with higher demand.
A memory card can affect your camera’s performance. Compact Flash Vs SD card have dominated the market for years, each bringing something different to the table. As camera tech evolves, picking the right card becomes essential.
Your card’s speed and compatibility are crucial for high-res photos or 4K video. Here’s how CF and SD cards compare so you can pick suitable ones for your camera and shooting needs.
Compact Flash cards are a solid choice for digital photography. SanDisk designed them in 1994 to deliver speed and durability. Initially, they had limited storage, but now they can reach over 1 TB. This expanded capacity is ideal for professionals who require reliable performance on ample shoots.
SD cards made their mark in 1999 and became crucial for consumer devices. Their compact size and lightweight won many users. The introduction of SDHC and SDXC standards allowed for additional storage and fast transfers. Their compatibility supports everyday photography well.
CF and SD cards are crucial for storing high-quality images and videos. CF cards are often chosen for professional work due to their superior speed and robustness. In contrast, SD cards are user-friendly and cater to a wider audience.
CF cards are made for high-performance cameras. They meet the speed and storage demands for quick captures. They’re excellent for dynamic photography, such as sports and wildlife. Their rugged design protects data in difficult environments.
SD cards excel in consumer cameras, action cameras, and smartphones. Their small size fits easily in lightweight devices, making them perfect for casual users. Action cameras, used in extreme conditions, rely on SD cards for their flexibility. They also accommodate various video formats and resolutions.
Professionals often choose CF cards for video work due to their impressive write speeds. SD cards, meanwhile, excel in compact camcorders that value ease and portability. This variety allows photographers and videographers to find the appropriate storage for their needs.
CF Type I cards are 3.3 mm thick and often used in consumer and professional cameras. They support up to 137 GB of storage and typically have transfer speeds reaching 90 MB/s. Most devices designed for Compact Flash will work with this type.
Measuring 5 mm thick, CF Type II cards offer larger storage capacities, often exceeding 137 GB. This makes them ideal for high-resolution images. They have similar transfer speeds as Type I cards and can use technologies like Microdrives, which are small hard drives designed for the CF card format.
CFast cards greatly enhance both speed and storage capabilities. Their SATA interface allows for transfer rates over 500 MB/s. With sizes 64 GB to 512 GB or more, they perform well for tasks like 4K video and continuous shooting.
The original SD card supports up to 2 GB. While suitable for standard-definition video and images, it has become outdated for most modern uses.
SDHC cards are faster than standard SD cards, sizing from 2 GB to 32 GB. This speed makes them efficient for high-definition video recording and detailed photography.
SDXC cards provide storage options from 32 GB to 2 TB. These cards are tailored for professional photo and video work. They often reach speeds of 300 MB/s or more, ideal for 4K and 8K recordings.
UHS-I cards support SDHC and SDXC formats with transfer rates reaching 104 MB/s. They are perfect for tasks that demand fast writing speeds, like burst shooting.
UHS-II cards reach speeds up to 312 MB/s. They feature an extra row of pins that enhance data transfer rates. This makes them ideal for professional applications needing rapid writing and reading, such as 4K video capture.
When comparing CF and SD cards, a few key points stand out:
CF cards are large and more cumbersome. In contrast, SD cards are compact, making them easier to handle and store.
CFast cards lead in speed, suitable for high-performance tasks. UHS-II SD cards also provide competitive speeds, while traditional CF cards typically lag behind modern SD technology.
Professionals often opt for CF cards in DSLRs and high-end cameras, drawn by their durability and speed. SD cards are more frequently used in consumer devices, action cameras, and mobile phones for their adaptability and ease of handling.
CF cards provide a higher storage range, typically from 128 MB to 512 GB, with premium models reaching up to 1 TB. This capacity is excellent for professional photographers needing extensive storage for high-resolution content. SD cards available in SD, SDHC, and SDXC formats range from 2 GB to 2 TB, with SDXC being preferred for high-capacity requirements. The choice between CF and SD often depends on camera compatibility and the volume of data.
CF cards utilize UDMA technology, achieving write speeds of 167 MB/s depending on the mode. In addition, this feature is ideal for fast shooting and high-quality video. In contrast, SD cards operate on UHS standards. UHS-I can reach speeds of 104 MB/s, while UHS-II can go up to 312 MB/s. V-rated SD cards indicate their video performance. Higher ratings ensure better 4K and 8K video capture. Always pick a card that matches your device’s capabilities.
CF cards mainly use the FAT32 file system, supporting files up to 4 GB and ensuring compatibility with most devices. Larger-capacity CF cards increasingly adopt exFAT, which allows for bigger files and enhances data transfer efficiency. SD cards utilize FAT32 for sizes up to 32 GB, while SDHC and SDXC primarily rely on exFAT. Understanding these file systems helps users avoid size limits and compatibility challenges.
First of all, starting with compatibility. Then ensuring your camera works with CF, SD, or both formats. Then, checking with performance. If you capture high-res images or 4K video, choose high-speed cards that fit your camera.
Capacity is another consideration. Evaluate how much storage you typically need. Furthermore, if you often shoot extensively, larger capacities like SDXC or high-capacity CF cards might be needed.
SD cards usually provide better value, while CF cards offer speed and durability, which can be worth the extra cost for pros. Therefore, a good choice to match your photography style, budget, and equipment.
MMC Plus
1.In September 2004, the MMC Association launched MMC plus and MMC mobile products. The size of the MMC Plus card is the same as the ordinary MMC card, and it has a faster read speed. When it works at 52mhz frequency with an 8-bit data bandwid
Memory stick was developed by Sony, it has many applications, making it possible for portable devices to have better transmitting speed and larger capacity.
You need to buy memory card with different specification based on how you use your camera. Storage cards with faster speed can bring you better experience and the ones with larger capacity can store more data. But always pay attention to buy cards that can be supported by your camera.
There are many memory cards in the market. When purchase, it is recommended to buy cards as quickly and large as possible. UHS II and V90 will become the mainstream in the future.
Kingston has released two V90 memory card, they both have high transmission speed and large capacity. They are the top of their kinds.
There are many parameters on the SD card labels, regarding speed, performance and so on, the author briefly introduced the meaning of main symbols. Those standards can be applied to micro SD card as well, but CF card may apply to different standards.
Various memory cards are available, with different performance, they can be categorized to different groups. Some cards have wonderful reading and writing speed, some are cost-effective, while the others may be adapted to suit different scenarios.
