Received my cards to day and the 128GB card will not run at UHS-II speeds. The 256GB will no longer run at UHS-II speeds but did initially. I have no idea if it is the cards or the adapters as nothing I have that is microSD UHS-Ii native can do a speed test and the only adapters I have are the ones I was sent. @Adata

TheProfosistAre you going to test with a 3.0 compact memory card reader in addition to theirs? I have one of those but none of my equipment USB slots are marked UHS-II , simply USB printed on camera side. At the very least i do know their stated output specs. of 100mbs at 4k H.264, other than that, "deeper" specifications are not available to me.
THIS FLAG by Crystal Disk Mark: CrystalDiskMark 4-6 uses Microsoft DiskSpd (The MIT License). So, the benchmark result is NOT compatible with 3.0.x.

- The result depends on Test File Size, Test File Position, Fragmentation, IDE(PATA)/SATA/RAID/SCSI controller and CPU speed etc…

ItalnstallnEven a UHS-I card can hit V90 certification. A card should hit its rated specs which in this case are higher than its certified for. It also should mysteriously drop down to UHS-I from UHS-II speeds during use.
