I'm a tech but not to the point of measuring performance and complaining when a product doesn't fit (by quantity). Functionality is more important to me. I bought this card because of the size and storage speed (capturing 4k videos takes *a bit* haha) and the fact that I trust the SanDisk name for SD cards. Well it works fine. Now I've moved all my mass storage apps to it including camera storage and other app related issues (which are definitely app related as other similar apps find my data on the card with no problem), all to be expected.
