A Guide to Speed Classes for SD and microSD Cards

Approximations: Results and 4K UHD (3840x2160) and 6K (6144x3160) video support may vary based on host device, file attributes, and other factors. 1GB=1,000,000,000 bytes. 1TB=1,000,000,000,000 bytes. Actual user storage less. Impressive transfer speeds make this durable SD card ideal for enthusiasts who a mix of action stills and high-res video.What’s more, this card comes into its own on random read/write speed tests. Here, we saw the fastest performance we’ve seen from a microSD card, reaching speeds of over 12MB/sec. Other cards from Lexar, Kingston and Samsung are catching up, but this is still the speed king for app and game performance. Given that it’s only slightly more expensive than the basic Ultima Pro, that makes it one of the top options for smartphone or Switch use. Storage is a crucial part when using a dashcam and high-endurance cards are designed especially for heavy use. Performance wise V60 cards are relatively middle of the road – they meet the demands of most high-end cameras, with minimum write speeds of 60MB/s. Yet despite this impressive performance, they’re overshadowed by the faster V90 SD cards; and they’re more expensive than the V30 cards, so what else can a V60 do to impress? Provide you with masses of capacity at a decent price, that’s what. 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. Different camera models have specific memory card requirements. A few cameras, like the Canon EOS 7D, 70D, and 80D, can use V60 and V90 cards. Likely, they work better with V60 cards. Multiple cameras, such as the Canon EOS R5 and R6, and Sony a7 series cameras, are better with V90 memory cards. 2. Project Requirements

microSD card V60 (256GB) - tested for full size SD card

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. The Integral Ultima Pro might be cheap, but it’s still capable of respectable speeds. We logged its sequential read speeds at 96.1MB/sec and its sequential write speeds at 87.4MB/sec, although it came in slightly slower on our random read/write tests. Having now settled into life with these larger capacity cards I can say I’m far more comfortable, and with the advent of CFExpress the additional robust build quality helps to reassure me further. But, now I have an SD card with 1TB of storage in a format that I have never felt is that robust having gone through many in the decade or so that the format has been widely used. 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

The best microSD cards to buy in 2023

It didn’t match claimed speeds in testing, but this is still a fast, reliable card for pros who are happy to pay for performance. The Sony SF-G Series Tough UHS-II stands out from the crowd by bringing some extra ruggedness claims. It comes with a premium price, but that isn't surprising considering its build. Branded as dirt, dust, water, and grime-proof by Sony, it’s also purported to be 18x stronger than standard cards thanks to a unique resin-moulded design, which can be felt easily in the hand. It also has a noticeable protective protrusion at the rear. 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.

First, look for Class A1 or Class A2 markings. As for capacity, microSD cards can hold up to 512GB of storage. The cards with a rating of V90 should offer you a minimum sequential speed of 90 MB per sec. These cards are specifically designed for cameras that can record 8K videos. Of course, the devices with that capability are pretty rare, and so are the V90 cards. However, the standard and compatibility are expected to grow, focusing on the 8K video recording. V60 When it comes to the high-resolution end of the market the capacity goes from being nice to have to more of a necessity especially if you’re shooting a mixture of stills and video. A couple of years ago, a 128 or even a 256GB SD card would give me the fear. Now I’m looking at a card with 1TB of storage, can a card of this size be safe to use, what if it goes wrong?

UHS Speed Class

years warranty in Germany, Canada and regions not recognizing lifetime warranty. See www.sandisk.com/wug SDXC V60 cards are tested and certified to operate at a minimum sequential write speed of 60MB/second, while SDXC V90 cards are certified to operate at a minimum continuous write speed of 90MB/second. You will need to ensure that your device’s HUB controller unit supports high speeds. Else, you will not be able to utilize the cards to their full potential. We hope that, by now, you know what V90 SD Cards are. Let’s have a look at some of the top V90 Micro SD Cards for 8k video capture. Top V60 & V90 Micro SD Cards for 8k Videos 1. Sandisk 128 GB Extreme Pro ( HS-I/U3) One final thing we need to make clear is that speeds will depend on your microSD card reader. The reader built into your average laptop might not be capable of reading from or writing to the fastest cards at their full speed, and we’ve found huge variations in external readers, even those bundled with high-performance cards. If you’re investing in one of the faster microSD cards, grab the matching adaptor from the same manufacturer, or from a credible manufacturer like Lexar, SanDisk, Kingston or Integral. That goes double for UHS-II cards. What if I’m buying for an action camera or dashcam? Finally, there’s the Video Speed Class. These are denoted by a V symbol, followed by a number representing the minimum write speed, in MB/s. The speed classes are V6, V10, V30, V60, and V90. For example, a V6 means the card has a minimum write speed of 6 MB/s. Cards can obviously be faster than that, but if you need to hit a minimum speed, this is a good symbol to look out for.
