Yep - I do that for backup (as opposed to resilience). I can't afford (and don't need) to backup my entire Tb+ of TV recordings. > I don't know of many people with good experiences using RAID.

It offers no resilience (so more AID than RAID) but it means that you can issue say 4 read requests to a 4 drive RAID0 array and the head from drive 1 skitters away to service request 1, drive 2 does request 2 , drive3: request3, drive4:request4 ... all in parallel so you appear to get 4 times the performance - equivalent to say: 2ms seektime and 300Mb/s *real* transfer speed - still laughing?
