Along with that, you also have access to the Video Speed Classes as well. We currently have the speed classes – V6, V10, V30, V60, and V90. These numbers specifically denote the sequential write speeds in MB per sec. For instance, a V6 card will offer a sequential write speed of 6 MB per sec, while a V10 card gives you a rate of 10 MB per sec. Please note that these speeds refer to the minimum sequential write speed provided by each class. The actual cards with those specifications can offer an extended speed performance than what is specified to be minimum. What are the Classes V30, V60, and V90?

These SD cards offer various utilities and features that can enhance the user experience. These utilities can include built-in error correction codes (ECC). This is to prevent data corruption, data recovery software, write-protect switches, and compatibility with different file systems. Both the V60 and V90 SD cards generally provide similar utility features.We hope you like our article on V90 Micro SD Cards for 8k Video capture. Even though we are still years away from getting real benefits with these SD Cards, it’s great to have them on the market already.

The Transcend SDXC UHS-II U3 is a belter that delivers whether you're shooting raw files or high-resolution video. While the 64GB maximum capacity (the alternative being 32GB) may appear a little modest at first compared with other options here, the performance is anything but, with blisteringly swift read and write times of 285MB/s and 180 MB/s respectively. Given that the price for these two memory card types has a huge difference, you may be wondering… is this also the case when it comes to their performance? Switching to record Fine* Jpegs boosted the burst depth significantly to 65 images, but that’s someway behind what was possible with the Lexar Professional 2000x SDHC/SDXC UHS-II, Kingston Canvas React Plus SDHC/SDXC UHS-II and PNY X-Pro 90 SDXC UHS-II cards. Shooting Fine-quality Jpegs increases the burst depth again, but at 78, it’s still behind the other cards I’ve tested recently, only beating the Manfrotto Professional SDXC UHS-II card. The space you require on an SD card depends on your specific needs. If you frequently capture high-resolution photos or record lengthy videos, you may need a larger SD card with storage options like 128 or 256 gigabytes. Do not forget to make sure that you have enough room to store all your multimedia files without running out of storage. 3. UtilitiesBut it’s a good idea to look at what the maker says about the stuff to make sure it works with your thing and has any extra things you might want. 4. Cost However, the UHS speed class is different, and will be displayed as a number inside a symbol that looks like the letter "U." UHS stands for Ultra High Speed, a standard of data transfer that SD cards use. U1 has a minimum speed of 10 MB/s, while U3 has a minimum rate of 30 MB/s. U3 cards get their increased speed from additional pins that let them send higher quantities of data simultaneously. WHY INVEST THOUSANDS ON CAMERA EQUIPMENT, BUT CHEAP OUT ON SD CARDS? KEEP YOUR MEMORY CARDS PERFORMING LIKE NEW with ProGrade Digital Refresh Pro software (available separately). All flash memory slows down over time; Refresh or sanitize your card to keep it at peak performance. And monitor the health of your cards before an important shoot. The V-Class ensures that the SD card has a minimum sustained performance for recording videos. It is specifically designed to support recording multiple video streams, 360-degree capture, virtual reality content, and videos with 8K and higher resolutions. This means that if you want to capture high-quality videos or use advanced recording features, you must choose an SD card with a higher Video Speed Class. V60 vs. V90 SD Card – What’s the Difference In another real-world test, I was able to transfer around 9.7GB of images (100 Fine* Jpegs and 100 14-bit uncompressed raw files) from the Nikon Z 7II in 1 minute 44 seconds.
