Editor's Notes

February 18, 2019:

MicroSD storage is remarkable, in that it's physically tiny, but holds a whole lot of data. It's one of the many, many benefits of owning an Android phone (although at least this editor is a little biased, regarding the Android vs. iOS debate). You may notice there are tons of different cards on the market. They're not all intended for smartphones, though, and currently (and for the forseeable future), the UHS-I standard represents the best performance you'll find. The Samsung Evo Select remains not only one of the fastest, but almost certainly the most reliable and most respected option. If you insist on top-of-the-line speed, though, check out the SanDisk Extreme, which is known to be a touch faster than the Samsung, although its largest available size is 400 gigabytes. The SanDisk Ultra doesn't boast the highest-tested throughput, but insofar as dollars-per-gigabyte go, it's at the front of the pack. Lexar also offers some good options, including one of the fastest microSD models on the market, although that is considering the unit's UHS-II specification, which only high-end tablets, laptops, and cameras can take advantage of. No matter which you choose, make sure to test it out as soon as it arrives, as manufacturers are generally quite dedicated to ensuring that you receive an authentic, error-free product, that works right the first time.
