The high-speed reading and writing performance of the memory card allows photography enthusiasts to experience the smooth and incomparable data access and transmission speed when transferring files to the computer following taking pictures or recording high-quality videos! The current mainstream digital camera high-end memory cards support up to SDXC UHS-II. I often go to some photography clubs and see that netizens who are new to digital camera photography have great doubts regarding the choice of memory card, and do not know how to choose the right one. Many new photographers who have just bought a digital camera will think that the memory card is just a medium for storing digital files, so when choosing a memory card, they will only focus on whether its capacity is large, whether the price will be too expensive, and will not cost too much. Pay more attention to find out whether your device can be used with a memory card to obtain the best performance in data access and transmission. If the memory card is only concerned regarding the low price, it will often choose a poorer specification, causing the shooting to freeze and the video to be interrupted from time to time. If you are unlucky and buy an unknown brand product with doubtful quality, the actual transmission speed may not be as marked as the data, and there is a risk of sudden data damage!
How to understand SD card specifications?
Usually we can see in the camera specifications that support various SD memory cards, including SD, SDHC and SDXC, and the latest SDUC released in 2018 has not yet been marketed, so let’s not mention it; the capacity of most memory cards today is between 64GB – 512GB, so most of the memory cards on the market are SDXC. If you buy SDHC memory cards, the capacity and speed are relatively low.
In addition, the new speed grade Ultra High Speed (UHS) formulated by the SD Association in 2010 currently has two grades, U1 and U3, representing the minimum write speeds of 10 MB/s and 30 MB/s, respectively. In recent years, as the popularity of video recording has increased, the SD Association has formulated a new Video speed grade, represented by V + minimum writing speed. For example, V10 means the minimum write speed is 10 MB/s, V90 means the minimum write speed is 90 MB/s
Finally, everyone should pay attention to that there are two transmission interfaces for SD cards, including UHS-I (theoretical speed is up to 104 MB/s) and UHS-II (theoretical speed is up to 312 MB/s). s), and the mainstream high-end SDXC memory cards currently on the market are all UHS-II interfaces. But in terms of price, UHS-II will be much more expensive than UHS-I (compared to the same capacity)!

speed test
High-speed memory cards have the characteristics of fast read and write speeds. When used in digital cameras or digital video cameras, it can greatly shorten the time for image processing following shooting. Before sharing the test data, I would like to remind everyone that the transmission speed of the memory card will be more or less affected by the transmission equipment. When using software testing, the test results will also be different due to different software technologies.
Using Apple Mac mini M1 version, with OWC external USB-C card reader, and AmorphousDiskMark 4.0 speed test software for data access speed test, the read speed reached 276.14 MB/s, and the write speed reached 236.08 MB/s the s
The following changes to the Windows laptop platform test
Using the AJA speed test software to test the data access speed (also through an external USB-C card reader), the write rate reaches 266 MB/s, and the read rate reaches 267 MB/s
Using the CrystalDiskMark speed test software to test the data access speed, the reading reaches 279.8 MB/s, and the writing reaches 255 MB/s
Tested with AS SSD Benchmark, the read speed reaches 264.56 MB/s, and the write speed reaches 228.93 MB/s
Summary of experience
In terms of the overall test data, the highest reading speed we tested was 280 MB/s, and the writing speed was 267 MB/s. Although the official reading speed was measured at 300 MB/s, the writing speed was a breakthrough. Official 260MB/s data. Since the test data will be different due to the test software, the card reader device will also have some influence. We used three different card reader devices for this test, all of which support the UHS-II standard. The actual comparison found that The data is similar, but definitely not exactly the same.
The high-speed SDXC memory card can help you to avoid the speed limit or problems in taking photos or videos due to the speed limit or quality problems of the memory card when using high-end digital cameras/camcorders. In addition, it is very important to When the data is taken out to the computer equipment, it can be completed quickly to shorten the operation time. After all, time is money!
