Having read this thread https://news.ycombinator.com/item?id=23741640 and owning a RPi 4, I bought a SanDisk USB3 64GB Ultra Flair stick (VID:PID -> 0781:5591) only to discover that it's using the usb_storage driver and not uas driver, i.e. not using SuperSpeed.<p>Is there a list of USB3 sticks that work at SuperSpeed with the Raspberry 4?<p>I also found the quirks list (https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/tree/drivers/usb/storage/unusual_uas.h?h=v5.8-rc4) but there is no entry for the SanDisk stick.
It is important to note that post was testing SSDs with an external interface. I don't believe flash-drives are built to handle that kind of bandwidth, although am not an expert.

Every usb 3.0 drive supports SuperSpeed. SuperSpeed is the name of 5Gbit/s bitrate transfer mode.<p>What you are looking for is UASP support <a href="https://en.wikipedia.org/wiki/USB_Attached_SCSI" rel="nofollow">https://en.wikipedia.org/wiki/USB_Attached_SCSI</a>
