About this deal

In other words, it’s a steal for smartphone and tablet users or anyone wanting more storage for their Switch, and still a good option for your average DSLR or compact camera. Unless you find the Ultima Pro Premium High Speed even cheaper, buy away.

There are two types of speed indicated on an SD card “C’ and “U”. Each SD or Micro SD card has a speed rating, called a class. Larger class numbers correspond to a faster level of minimum performance, allowing files to be copied or recorded at a higher speed. The class rating system is actually quite simple to remember: the number after each Class corresponds to the minimum sequential read speeds, in MB/s. So Class 2 is 2MB/s, Class 6 is 6MB/s and so on. On top of this, most cards now have a “V” (for video) rating, going from V6 all the way to V90, indicating write speeds of 6MB/sec to 90MB/sec. You need a V30 card to shoot 4K video at speeds of 60 to 120 frames per second, while V60 is the base level for shooting 8K video at 60fps. V90 is theoretically capable of handling 8K video at up to 120fps. However, given that only a handful of professional-grade cameras can offer that, and that they tend to use the larger CFexpress 2.0 cards for storage, this isn’t what you might call a must-have.

About Micro SD

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? On the face of it, the SanDisk Extreme Pro seems overpriced. This U3, V30, UHS-I card is significantly more expensive than the Samsung and Integral competition at most capacities, and when tested on our SanDisk ImageMate Pro card reader it wasn’t any faster, at least on sequential read and write speeds, which were 96MB/sec and 85.4MB/sec respectively. As more devices incorporate the use of microSD, manufactures have consistently improved the cards, and improved the memory available massively; storage ranges from 2GB up to 1TB or more. Additionally, microSD cards have seen much improved data transfer speeds in recent years, a crucial quality as they being to hold significantly larger files. MiscroSDHC: 2GB to 32GB compatible with MicroSDHC or MicroSDXC formats, which means almost all smartphones.

The best microSD cards to buy in 2023 1. Integral Ultima Pro Premium High Speed: Best-value microSD card at higher capacities 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. Surprisingly, it’s easy to end up falling into various traps such as terrible performance, overpaying or worst, the card not even working at all. This YouTuber shows you which MicroSD card to choose for your drone, camera or smartphone. All abbrevations and specifications explained. We supply memory for mobile phones and digital cameras specialising in a vast collection of SD Cards, Micro SD Cards and USB Flash Drives. Our range also extends to top brands of electronics, camera accessories, Android accessories, iPhone and iPad accessories, and plenty more.These standards cover the speed of the interface between the microSD card and your device (or memory card reader), as this can also limit the maximum speed of data transfers between the two. UHS-I has a maximum speed of 104MB/sec, and you’ll usually see a Roman numeral “I” beneath the U1 logo. UHS-II takes that up to 156MB/sec (with data transferring in both directions) or 312MB/sec (with data transferring in only one direction).
