No, this is a *bad* plan.
You will rattle the internal disk *hard* because it will be rebuilding
he external disk regularly. It will fail much sooner than you expect.
The correct solution is to *alternate* which drive you move to storage.
The first time you store Bay A. And rebuild from Bay B. The *next*
time you store Bay B and rebuild from Bay A. That way no drive gets
rattled more than twice (once on its own initial rebuild, once to
rebuild the other drive, then taken to storage).
Hardware limitations. I have physically room for two internal disk
drives. No removable drive bays. At the moment, one internal drive
is 200GB SATA and contains all of the system except for the large data
files. The second internal drive is 500GB SATA and will become the
data disk. One external drive is 300GB SATA on a USB2 bridge, and is
presently the data disk.
I can attach any reasonable number of other drives using USB or
Firewire but would not like to clutter up my physical desktop with
more than two or so. Maybe I need a larger desk to put things on.
So far I have lots of interesting advice to think about. Thanks everyone.
