I think all my USB ports are USB2. It's slower. What you post above is
about what I get on my external eSATA. If I were using USB3, things may
be different. Maybe. ;-)

Those particular drives sat on the desk next to my computer. They
rarely moved. Heck, I rarely unplugged them. Just turn them off when
done.

Every enclosure I buy has a fan. The enclosures were pretty well built
as far as the case goes.

After a while I'd start getting errors and it would either remount ro or
just unmount completely. After a while, the drives wouldn't respond at
all. They spin up but it's as if they are not connected with the data
cable. Eventually, I plugged them into my computer as SATA drives.
They still wouldn't show up. It was as if they were not there. They
did spin up tho.

I bought a SMR before I was aware of the problems with them. It's just
a backup drive but I still have to wait for it to stop bumping before I
power it off. Sometimes it only takes a few minutes, sometimes it bumps
for a while. The CMR I use as a backup drive, different data, is
smaller. It doesn't do that so I can unhook it right after it finishes.

I've never had a SSD. Thinking about it tho.
Hmmm, just realized I didn't do my usual Sunday updates and backups.
Ooooops. :/
