I purchased a 2TB SSK SD500 portable SSD for another use, but I tested it on my Pi 4B first, and got great results.
First of all, it's USB 3.2 Gen 2 and USB-C (but it also includes a USB-A cable), and it's tiny.That's roughly 6.85 cm x 3.75 cm x 1.25 cm in the homeland of the Raspberry Pi.
The one I tested supports UASP and TRIM in RPiOS Bookworm 64-bit out of the box (no UDEV rules or quirks nonsense).
And yup, it's also fast.
Won't be as fast as NVMe on a Pi5, but it's USB so you won't need an NVMe HAT or Base.
As tested:
Raspberry Pi 4B 4GB Rev 1.1
Official USB-C PSU (5.1V/3A)
Raspberry Pi OS Bookworm 64-bit with desktop (cloned from another USB drive)
2TB SSK SD500 Portable USB 3.2 Gen 2 SSD (using included USB type C to A cable)
Keep in mind that my test sample size is exactly ONE, but that one worked great. ![:D]( "Very Happy")
This also wasn't an extensive test. I just cloned my existing OS, booted the drive, ran update/full-upgrade, rebooted, then ran RPi-Diagnostics and used it for "normal" kinds of stuff, like surfing around in Chromium and using GIMP to edit/crop/shrink the image above.
