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

Product Information

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 Well, you are visiting a stall for a memory card or an SD card and suddenly find that there are several classes of memory cards available. This can indeed be confusing, and choosing the right SD card may appear to be a difficult task. We thought of explaining what the V60 and V90 classes of SD cards stand for from that perspective. The Memory card Classes – An Overview If you’re shooting raw files you want a card that can handle sequential bursts of the highest quality imagery, as well as a capacity that allows for sufficient storage to avoid having to swap cards every five minutes. Both the V60 and V90 SD cards come in various storage capacities to suit different user requirements. SD cards can store different amounts of data. Different SD cards come in varying storage capacities. For example, a few can hold 256 GB or even more, while others have a smaller capacity of around 32 GB. With that, remember the size of the SD card only affects the amount of data and doesn’t impact its performance.

One of the most obvious ways to differentiate between memory cards is how much storage they have. A 16GB card might be fine for an afternoon wandering around your local wildlife reserve, but videographers looking to shoot all day could get frustrated with having to constantly swap over cards. 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 Transcend did superbly in its speed tests, excelling the claimed write speed (180MB/s) with a whopping 224MB/s, but falling slightly short on the read speed with 224MB/s. Overall, that makes this card an impressive buy at a reasonable cost. This card is ideal for high resolution, rapid-fire stills photography and 8K video, with 4K and HD video being recorded comfortably, too.As an evolution of the XQD format, CFexpress is one of the best memory card formats around. However, it's currently only available with a limited number of high end cameras (mostly from Canon, Nikon and Panasonic). However, it's worth noting that the release of the Sony A7S III brought a somewhat confusing split into two different variants of CFexpress cards. Up until this point, all CFexpress-compatible cameras used CFexpress Type B cards (yes, 'B' does come before 'A' in this case!). Meanwhile, CFexpress Type A cards are smaller and slower. Crucially, Type B and Type A cards aren't interchangeable, so a camera such as the Nikon Z7 won't be able to accept a CFexpress Type A card.

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. The perfect choice should be dependent upon the type of device you are using the card with. If your device supports multiple card types and speed classes, the card types should be available beside the logo or instruction manual. You can choose the card depending upon the logo and the instructions. This should apply to all card types, including the video speed class or any other speed class types. Most of the time, the device manufacturers will specify which cards are ideal for a particular kind of application. 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. The V60 SD card supports the video recording up to 4K UHD. The V90 card, on the other hand, supports the video recording efficiency of up to 8K UHD. Both the cards support a frame rate of up to 60 to 120 fps. So, what should you Look for when shopping for an SD card?LIGHTING FAST 250MB/s WRITE SPEED – INSTANTLY SAVE high resolution recordings to your device, ALL WHILE maintaining super sharp focus. STOP waiting around for your images/recordings to upload, with our Read Speed of 300 MB/s even your most robust work can be uploaded in seconds! If you are dealing with 8K videos and high-speed video recording, you will require a V90 SD card. Now that 8K videos are on the verge of becoming mainstream, that would be something that necessitates V60 and V90 SD cards. 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 V-Class in SD cards stands for Video Speed Class. They start with the letter V and are followed by a number like V6, V10, V30, V60, or V90. These numbers tell us how fast the card can write information in a row, measured in megabytes per second (MB/s). The SD Card Association introduced the Video Speed Class to identify cards capable of handling higher video resolutions and recording features. Taiwanese company Transcend is another long-term player in the memory card market – and still makes many low-capacity cards, meaning they’re accessible to those on a tight budget.

Both U1 and U3 memory cards can utilise the UHS-I bus interface, but are not compatible with the UHS-II bus interface. Our stand-out best SD card is the Transcend SDXC UHS-II U3. With a Class 10, V90, U3 and UHS-II rating, we thought it would be fast enough to capture almost anything modern devices could throw at it, but we weren’t expecting the speed results we got. The new Video Speed Class ensures that a few performance grades are taken care of. The speed class is designated by the transfer speeds in megabits per second. This is specified with the letter V. The ideal levels include V6, V10, V30, V60, and V90. That does not mean the V standard would remain the sole reference. The Video Speed class can co-exist with the other speed classes. If the different classes support the required video performance and video transfer speeds, it will be equivalent to using a V class. For instance, the V6 type refers to a minimum transfer speed of 6 MB per sec. From that perspective, a Class 10 card is almost equivalent to a V10 card. How do the cards Differ from each other? You can find the best card for your hardware device by choosing the same speed class or higher than the one required for your device. For example, if your device requires a Class 4 memory card, you can use Speed Class 4, 6 or 10. If your device requires a UHS Speed Class 1 card, you can use UHS Speed Class 1 or 3. The same functionality applies to the Video Speed Class as well. Note, using a higher-rated card that goes beyond the speed class requirement for a device will still work, but you won’t be experiencing the full benefits of the higher speed class since the device only supports the lower speed class. The V90 standard requires manufacturers to ensure a minimum of 90 MBPS sequential read speeds on their SD Cards. Currently, there are plenty of SD Cards that meet the minimum specifications. If you are planning to capture and store videos in 8K, these are the ones that you need to go for. 1. ADATA “Premier ONE” V90 SDXC II for 4k & 8K Videos

The UHS – I was introduced in the year 2010 and was followed by UHS-II in 2011. The UHS-II brought the extra row of pins to improve the bandwidth available. However, for the highest capability of the UHS-II cards to be utilized, you need a supporting device or phone. As of today, there aren’t any devices that support it. Video Speed Class is the most recent system, denoted by a “V” followed by a number (90, 60, 30, 10, or 6). The number represents the minimum sustained write speed in MB/s. For example, a V90 card has a minimum sustained write speed of 90MB/s and is ideal for capturing high-quality 8K video. Final Words 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. 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.
