About this deal
MiscroSDHC: 2GB to 32GB compatible with MicroSDHC or MicroSDXC formats, which means almost all smartphones. 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. If you’re in need for a new one for your mobile phone, tablet, camera or for some other reasons and, there are several factors you need to consider first before buying and we have all the key information covered here. Always remember that it sometimes pays to choose wisely.
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.Often, fast sequential speeds come at the expense of random read/write speeds, but the A2-class 1066x is an exception; it’s not as speedy as the Integral Ultima Pro Professional High-Speed card below, but it’s faster than the SanDisk Extreme Pro and Samsung Evo Plus on this count, making it a fine all-round performer. If you’re looking for a card that can run apps or cover video on your mid-range or high-end smartphone, you won’t get much better than this.
MicroSD comes in 3 formats; SD, SDHC and SDXC, which will determine whether or not the card you’re about to buy will be compatible with your gadget. Both full-sized and micro cards are based on the same spec and each format is defined in the SD spec, howeer the don not work in the same manner. For example, if the card slot on your gadget only supports MicroSDHC card, then a microSDXC card will not work on it. 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.As a general rule, it’s always a good idea to buy specific cards for specific tasks. This way you can guarantee the best combination of speed and capacity for your hardware to give you the best possible overall performance. 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?
