Yes, that would be optimal. My raid5 is on an HP SC10 with 5 Seagate 181gig
drives plugged into a Linux server acting as a SAN server to 7 initiators.
That SAN server has roughly 2TB of raw storage hooked up to it. Keep the
server and all the storage on UPS takes many many batteries. :)

Why not use your existing Live TV buffer RAID0 set as your recordings drive 
and your RAID5 set for archiving the recordings you want to keep, using the 
perl script to move them when your not recording anything (or are recording 
only a few things that the raid0 array can handle).

Then get a large UPS so you never lose power without being able to shutdown 
first, if the power outage is for that long a period of time? (I assume a 
proper shutdown negates the need for RAID5 to resync upon reboot?)
