Nope ... just a "calculated" risk. I have a finite number or
drive bays in
the server case ... Running RAID0 over RAID5 "gains" me about 30
movies of
storage space that would normally be used for the "redundancy"
part of RAID5
*PLUS* the load on the server is considerably less as the CPU isn't getting
called on to do all the XOR calculations for reading and writing data under
RAID5.
If a drive goes I lose 260(ish) extracted DVDs *BUT* they're all discs that
I own and so I can recreate them - I *MAY* move back to RAID5 when I slap
that server over into a rackmount chassis but who knows?
Backing up the 2.4Tb plus of data that I have there across the two servers
just isn't going to happen on anything practical - so I mirror any data
that
I can't recreate and accept that I may have to spend a month of weekends
re-extracting DVDs if it does go titsup.
