If you’re looking for a new MicroSD card for your camera, smartphone, or tablet, then it would make sense to buy the fastest and most reliable card available. Here’s what 688GBs of MicroSD storage looks like:
Here is a list of all the cards we have tested, sorted with the quickest average speeds at the top. We tested these cards using a MicroSD USB3 UHS-II card reader to get the fastest possible performance, using CrystalDiskMark.
We tested the fastest UHS-I and UHS-II cards available to us. To make the most of the high speed available with UHS-II cards, you’ll need a camera or device compatible with UHS-II cards, as well as a memory card reader that supports UHS-II. UHS-II cards can be used in UHS-I cameras and card readers, but you won’t get the benefit of the additional speed. On the left, above, you can see the extra contacts on the UHS-II card.
When taking photos write speeds are the most important, as this is the speed at which a device such as a digital camera or smartphone can write photos to the memory card, if this is slow, then it may slow down your shot to shot time or the amount of photos you can continuously take. The read speed is important for when you want to view the photos or copy them onto a computer or another device.

Another important factor to consider is warranty and reliability, ideally, you would want the most reliable card possible so that your photos are never lost, however, if the card does fail then a long warranty will mean that the manufacturer should replace or repair your card. Although recovery of images is unlikely when a card fails physically, recovery software is available to help recover accidentally deleted files, and some of these cards come with free recovery software.
Reliability can’t be determined on new cards, as it could take a long time for the card to fail if it ever does. Although, one thing to consider is how durable the card is, and if you look at Samsung cards, they are waterproof, shockproof, magnetic proof and come with a 10-year warranty so should survive much more Mis-treatment than others
