Even more strangely, proprietary SxS/XQD cards also don't support discard/trim, neither for devices nor from a PC. Only the more recent CFX cards support trim (most of them, but not with every reader, and formatting in a camera doesn't seem to issue them, perhaps to aid with data recovery in case of accidental formats).
- radicality 2y agoAre CFExpress cards similar/comparable at all to SD cards? Afaik CFExpress uses nvme, which will provide more features. Also, interesting thing one can do if you have a need for a CFExpress card (like a camera) and want to save some money. You can buy an adapter online such as the linked one, and then buy an m2.2230 ssd and put it in there. That’s how I made myself a cheaper 1TB CFExpress B card for my camera, and it’s doing just fine, even with 8k30fps at ~3.5Gb/s. https://www.bhphotovideo.com/c/product/1685487-REG/monster_adapter_sa_cfe1_2230_m_2_ssd_to.html https://www.bhphotovideo.com/c/product/1685487-REG/monster_a...
