I think you might be missing Caffeinate's point of interest, one which
I also happen to share. He's not looking for RAID, as I read it. He's
merely asking about hot-swappable IDE.
I am looking for something similar, actually, not for a RAID pretense
at all. Let me offer a clue:
- It's faster than tape or CD/DVD.
- It holds more data than tape or CD/DVD.
There are no removable media out there which will hold an entire drive's
worth of data, given maximal sizes of each. This has always been a problem,
and it's more so now given the sizes of disks vs. the sizes of tapes.
That stated, probably redundantly, I would love to have a hot-swap IDE drive
solely for this purpose. A drawer full of 100G drives can be had more
cheaply than DLT media of comparable capacity. The properties of a removable
drive also will insure that, since it won't be on line, I won't be tempted
to use it for something else.
