UHS-I standard is certanly important one for us. Yet another example here would be that 128G and 256G Lexar® PLAY microSDXC™ UHS-I Card doesn’t support A2 rating (nice that they publish this for our awareness). Now, as we would like to understand A2 standard (how many of small files are processed at the same time …) is it A2 stamp indeed feature that everyone here needs? This opinion might help: “So unless and until more devices and operating systems support A2 functionality, it’s best to avoid purchasing any A2 cards. If you buy an A1 card, you’ll get better performance now, and quite possibly forever. A2 might not technically be marketing BS, but in the real world, I stand by my assertion that it still is.”
Therefore Superior Pro (U3.A1) microSDXC (max. of 512GB 3D NAND) looks just fine to me (if you don’t mind). Anyway, here is link to Superior (A1.V30).
Another question of our (perhaps) concern, when about to use microSD that exceeds capacity of 128GB/256GB (per piece), is kindly posted here:
