ProGrade Digital SDXC UHS-II V90 300R Memory Card (64GB)

Product Information

While CFast cards look similar in size and shape to CompactFlash cards, they're not compatible (so don't try to jam one in your old DSLR!). This new-generation high-speed memory card format will be found in professional stills and video cameras. COUNTERFEITS ARE CRUMBLED: CUSTOM LASER-ETCHED SERIAL NUMBERS keep cheap counterfeiters at bay because our SD Cards are so difficult to mimic. Forged in our premium ProGrade Lab, we meticulously inspect each SDXC Memory Card before it ships out and laser etch a custom code on each one. The V60 video speed class, as you would be already aware, is for the cards with the sequential write speed of 60 MB per sec at the minimum. They are specifically designed for the 4K video recording. By virtue of many devices that support 4K video recording and transfer, we find the cards with the specification quite in vogue. V30 Card classifications like V30 or U3 are just categorizations of these speeds. There are three main classes: Speed Class (denoted with a number in a circle), UHS Speed Class (a number in an open beaker-like icon), and a Video Speed Class (V followed by a number). The numbers indicate the minimum writing speed when put under data transfer. Speed class is categorized into Class 2 (a minimum write speed of 2MB/s), Class 4 (4MB/s), Class 6 (6MB/s), and 10 (10MB/s). Choosing the best one for your camera depends on your camera's resolution, buffer size and burst shooting speeds. An additional clue is the UHS Speed Class rating, which is U1 or U3. U1 means it can write a minimum of 10MB/s (like Class 10), while U3 pushes the write speed up to a minimum of 30MB/s. More interested in shooting video? The Video Speed Classes are V6, V10, V30, V60, and V90, with V6 suitable for standard definition video recording and V90 capable of 8K video capture. 4K UHD video recording will require a minimum of V10 ideally, and HD video can utilize V6 or below at a push. How we test SD cards

It is not just cameras that use microSD cards, of course. And one of the most popular devices to use this memory type at the moment is undoubtedly the Nintendo Switch handheld console, and its baby brother the Nintendo Switch Lite. The slot in memory is not only great for expanding the number of games you carry, but also for taking screenshots and videos of your victories and adventures. Nikon was the first camera company to introduce XQD cards in digital cameras and a lot of people thought it would be short-lived, and since XQD has now evolved into CFexpress Type B, in some sense they were right. CFexpress cards are considerably faster than XQD cards (though that's not to say XQD is slow - far from it), and there are more manufacturers producing CFexpress cards than XQD, leading to more competitive pricing. Also, despite chalking up impressive read and write speeds of 252MB/s and 207MB/s respectively, the SanDisk Extreme PRO 300MB/s SDXC UHS-II proved to be one of the slower cards when it comes to moving files onto a computer. The shortest time I was able to transfer 100 Fine* Jpegs and 100 14-bit uncompressed raw files from the Nikon Z 7II (adding up to 9.7GB), was 2 minutes 37 seconds - that’s minute slower than the Lexar Professional 2000x SDHC/SDXC UHS-II. However, it should be noted here that the speed class does not necessarily specify the actual speed performance of a particular card. For example, you cannot conclude that a V60 card may not offer better performance than a U6 card.

What is UHS-I VS UHS-II?

In simpler terms, the V60 card is cheaper than the V90 card, but it has slower speed and performance. Furthermore, comparing prices from different retailers or online platforms is advisable to find the best deal that meets your requirements and budget. V60 vs. V90 SD Card – Which One is Better?

Well, during the early days of point-and-shoot cameras, a Class 4 card would have been enough for most of your video shooting requirements. However, the camera technology has progressed by many folds, and thus it has become necessary for the SD cards to support the additional features. The video cameras in the new generation have been capable of shooting in high resolution such as 2k and beyond – it is essential that better data transfer technology became necessary enough. The new video classes were introduced to ensure a higher transfer speed. The Video Speed Class is unique because it’s capable of utilising both the UHS-I and UHS-II bus interfaces. V6 to V90 speed class memory cards can use the UHS-II bus interface, but the UHS-I bus interface can only support V6 to V30 speed class memory cards. 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. SD cards are flash memory, which means they have no moving parts and instead rely on electronic chips to store data. While they don’t require power to store data, they can be damaged via water, fire and physical pressure. Some companies offer bespoke 'tough' versions that can withstand these elements, even remaining safe in extreme temperatures, so it's worth looking for those if you're going on an adventure. microSDHC and microSDXC cards will offer a similar performance to their larger SDHC and SDXC siblings. However, they're around a third of the size and can be used in the best camera phones and best action cameras.

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. SD cards, also known as SDSC cards, were the original type of SD cards. They have a storage capacity of up to 2GB and are formatted with FAT12 and FAT16 filesystems.
