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.  :/
