The only reason I was reading the reviewers comments in this
case, this was back around the time Newegg started stocking
disk types that weren't appropriate for home computer users,
and without any warnings in the adverts. Then, apparently there was a high
rate of return on the things people were buying.

There seem to be a few more warnings today.

SATA 512e    Home user
SATA 512n    Home user
SATA 4Kn     Will work at home, not recommended (tool situation not good)

SAS          Not a drive you'd want at home particularly.
             Many high performance drives, the self test "chirp" will drive you nuts.
             A certain number of items are meant for locked server rooms.
Diff.SCSI    Not a drive you'd want at home particularly.

I worked on a couple drives at work, one in one of our remote
labs, those were differential and the cables were 25 feet long
(and, all over the floor). But that was a long time ago, and
data rates were pretty low.

And the SCSI I've had in the house here, weren't really champs
either. Nothing really high rate. All I've got left in
SCSI here, is an async SCSI cable for the old scanner.

All my recent experience here is with SATA. And no 4Kn either.
Mostly 512e, a couple 512n.
