That's pure bullshit -- I use software RAID *specifically* because I value my data. I don't want to buy two hardaware RAID controllers to have one sit on the shelf just in case the first dies... and if the second dies you're SOL because they've lasted long enough that they're no longer available. Linux software RAID is available on any Linux system and if the system blows up I can put the drives in another system and *not* worry about it not being detected. As far as performance goes, I have some bonnie++ tests that I've run that show that at least on the few systems I've tested, software RAID 1 beat out hardware RAID 1 (these systems were IDE, SCSI-2 and Ultra320, with DPT RAID controllers for SCSI on P4 and I think regular Promise IDE RAID controllers on P3) -- not a huge difference in speed but one that at least tosses your "if you value performance don't use software raid" argument. Perhaps on a _heavily_ loaded server you might be right, but then again I feel that you're stupid for letting a server get so loaded up that it can't handle the simple mirroring algorithms in addition to normal file servering functions without degrading performance to a noticable degree. I used to believe that HW RAID was the only way to go. With RAID5 I still feel that is true to an extent. However if you're just mirroring there is _no_ significant advantage to choosing hardware RAID over software RAID. Not on IDE, and not on SCSI. In fact, there are advantages to choosing software RAID over hardware RAID, as I've mentioned above. > What matters as far as the computers being used is that you are unlikely > to get your hands on a real server class motherboard without having > bought it in a Dell or Compaq. It also matters as to the supporting Again I call bullshit -- Where do you think Dell and Compaq get their motherboards from?

Agreed. Personally I'd rather have a complete second system on the shelf that I can swap out within 15 minutes than rely on anyone plus a courier, but that's just me.
