I checked using lsusb and it said 480.  In my final process I was able
to encrypt the file (using openssl) and write it to the thumbdrive in
about four hours.  To make that bearable, I ripped that part out of my
backup script and made it standalone, so independent of when the backup
was taken, I can have this happen overnight or start it before dinner or
whatever.  But when it's done I have a tiny thumbdrive with an encrypted
file backup and encrypted database dump, which is what I need.

I wish it wouldn't take so long, but I can live with it.  Given I
verified the port speed, it must just be a slow thumb drive.  It makes
sense that a 16GB drive would be slower than a normal 4 or 8GB one.


Thanks all for your advice.
