Unless he doesn't do the mirroring at all! He'd save $400 in the hard drive department and could get a huge UPS on ebay or something. Make sure write-caching isn't enabled it'll be almost as good.
If you do mirroring and stripping and the strips are sharing a channel wouldn't it be fine if one of the channels goes out?

Never use master and slave with IDE RAID because one drive tends to kill the other on the same channel when it dies. Since your motherboard probably doesn't have four IDE channels which you can dedicate to four drives, you may need to add a PCI ATA add-on card. Cheap Promise Ultra133 cards would do fine for this purpose. http://3ware.com/ Otherwise there really is only one brand of real hardware IDE RAID from 3Ware. Do NOT attempt to use Promise or High Point Tech IDE RAID with Linux, as they are poorly supported, SLOW, and not really hardware RAID, but poorly implemented software RAID implemented in the OS drivers. Native Linux software RAID is faster and more reliable than Promise or HPT for RAID.
