Though RAID can do great redundancy in your disk drives, we wary of having a single-point-of-failure in your RAID card. - What quality of firmware is it running? - How good is its physical quality? - Are replacements for the controller available on short order were it to fail? (Will they be next year?) - Are the disks from that RAID controller readable without the controller?, or on a different model controller? As you might have guessed I am a big fan of software RAID as implemented by Linux. It is very well tested. And I know I can replace any needed parts at the local Microcenter, Fry's, etc. Why have one very specialized board in my system? -kb P.S. Another RAID warning: Don't run matched drives in your RAID set. Ironically, they might all be really high quality and not die a premature death, rather they might just wear out. And if they are all matched they might wear out at roughly the same time. For example, one dies and you replace it, and in the stress of the gigantic rebuild onto your new drive, another of the old ones dies... Replace RAID disks in a regular rotation.
