We just had a situation recently (Backup Exec but the point still
stands) where a tape drive failed so we bought a couple of 2TB USB disks
to use for a few days while the drive was diagnosed and replaced.

The first USB backup completed after about 36 hours and then the drive
failed completely (won't even spin up) 2 hours later. It's a 2TB drive
(1TB would have worked with about 2GB to spare!) and cost about AUD$235.

So now we have a $235 drive that can't be used anymore and can't be
returned under warranty because it is full of customers data, and can't
be erased because it's dead. Tried all the standard revival techniques
but it's a sealed unit so we can't open it up to test if it's a drive or
controller issue. If we had used encryption then it would have been fine
to return.

Just make sure you keep a copy of the keys and the password offsite :)
