One more update. I did some research on the older external enclosure
that hard drives just slide into, no disassembly to change drives, and
it is indeed a SATA 2 spec enclosure. Don't get me wrong, I love the
enclosure. I can swap drives in well under 30 seconds. It's a nice
enclosure and I wish I had some more of them just maybe SATA 3. If I
ran up on a deal with a couple more just like I have, I'd buy them, slow
or not. I like the ease with which I can swap drives. I mostly use
them for testing and updating a hard drive backup of /root, /etc and my
world file. I only update those every couple months or so anyway so
speed just isn't a issue.
So, now I know to expect a slower connect speed with that enclosure.
It's a Star Tech SAT3510BU2E. I wish they still made them like this. I
have found enclosures with multiple drives but singles are hard to find
with a eSATA port.
