They are still USB 1.1 however, so they won't be able to surpass that speed limitation over USB.

They’re not really designed to be adapters in that direction anyway; the more intended use is that you use it to image a drive to a file on an SD card, and then use that file with a GBSCSI or ZuluSCSI going forward.

The point is that you can do reads/writes to it on a super-faster SD card reader on your main system, and then also use it with the ZuluSCSI/whatever. USB long ago exceeded SCSI’s data rates.
