UASP makes Raspberry Pi 4 disk IO 50% faster

Friends, I have a question but I don't have a Pi 4 sitting around to test this:

Is it possible to run a Pi 4 using UASP if I set it up to boot from a decent (Sandisk/Samsung/etc) USB 3.1 pen drive?

Also, is this a reliable setup, or will the device be more stable if booted and run from a MicroSD?

I'm going to be testing a few different thumb drives in my next post / video. I have a couple SanDisk models and an Arcanite USB 3.1 drive that I'll be testing... but I don't believe they use UASP (haven't had time to confirm that suspicion yet).

Thanks Jeff, you’re doing a great service to the community here. I’ve tried to hunt around for a good system drive and fell short so far; support for UASP/TRIM in thumb drives is both rare, and seldom specified by manufacturers even when present. Looks like the only way is to buy a bunch and try.

I am not sure about which pen drives support UASP, but one thing of note is they recently updated their firmware (June 15th) to support boot over USB instead of the SD Card. I have mine setup this way now, using an external hard drive enclosure that supports UASP. Works great.

Almost all USB thumb drives are garbage for booting OS because very bad performance for random read/write (Getting worse over time). IIRC SanDisk Extreme Pro is an exception.
