(requirements)
* local (not cloud or other internet).
* at least 128 GB, more is better.
* write speed as good as or better than USB-3.2.
(very strongly preferred)
* write lockable and unlockable, just like them old 3.5 inch, 1.44 MB
floppys. Note that I want hardware locking and unlocking (like those
floppies), not software locking/unlocking (such as with command line
options).
(preferred)
* re-writable as opposed to write once only.
Blu-ray: is write-once-only, and is much too slow (4.5 MB/sec).
SDXC: some is lockable, but is too slow (100 MB/sec).
By comparison, I read that USB-3.2 realistically does 500-2000 MB/sec.
What do you recommend?
Side question: I searched for USB-4.2 and USB-4 hardware, hubs, and
sticks. I found nothing. Am I correct in assuming these are not yet
available?
Check RDX Storage, not cheap but I think it covers all your requirements.

Then search different brands and products.
