I encountered IO issues only with this brand, two different card capacities(64 and 256GB) bought from two different places.
Heavy IO operations like copying or deleting multiple files can lead to 100% cpu usage that can freeze whole amiga(no screen updates, elements on screen become unclickable). Copying folders between partitions of the same card, copying from card to ram, ram to card - all exhibit this issues. Writing the exact same disk image into SanDisk card resolved freezing issues completely.
Amiga used: A1200 rev 2b with pistorm32-lite+cm4+pcmcia ethernet card+original floppy drive. Emu68 version change doesn't seem to do anything - tested rc1-3 and WIP
Steps to reproduce:
Write coffin img file into Samsung Evo Plus card
Boot Amiga and open new shell window
run "copy /#? RAM: all clone"
Actual results:
Copy operations frequently stalls with HDD led changing to a solid bright orange light, stalls get more severe with time, during freezes amiga is unresponsive
Expected results:
Copy operation happens smoothly without freezes, amiga is usable during copying
Workaround:
(emmc|sd).low_speed in cmdline.txt seem to fix this issue but card runs at 25% original speed
