i actually am using a hardware IDE RAID 5 card in the server i mentioned . If you don't do it in hardware you do take a big performance hit. But raid 5 can sustain very high transfer rates though....it essentially is a raid 0 array with a parity drive. and since is it done in hardware you don't take a performance hit to your system as the OS doesn't even know there is a RAID array present aside from the driver. You essentially get RAID 0 performance with piece of mind. Your transfer rates would be detrmined by HD speed anyway as is true with any HD. SCSCI can get up there but many of the newer IDE drives do come very close ad stipping and the cost factor of IDE and you have a very cheap viable solution. I know i can sustain a full DV capture,read,write using the matrox DV codec in RAID 0 and my understanding of how hardware RAID is implemented, and from what i've seen personally from the perfomance, there is a very negligable perfomrance hit, though i don't know how different it is compared with normal DV as I have no experience with that.
I just use the RAID 0 for captureing as it sustains much higher trasfer rates than normal drives. But I got sine nice new high rpm western digital drives it helps.
As far as the loosing the other drive goes......if you mean loose the data yes, but the drive itself is still usable if you reformat or inegrate it into another array. But if you are using it for capture.....you can always recapture what you got or re-rip vob's.
