Lets define some terms: Hardware RAID - "pure" HW RAID, like the big SCSI boys, 3Ware, and Adaptec 2400 give you. One characteristic of such devices is that they have their own RAM, as well as being able to do RAID-5. Linux devices are /dev/something. Perhaps this could be called "unassisted HW RAID" Software RAID - "pure" Linux "Multiple Devices" RAID, where you have /etc/raidtab and your devices are /dev/mdX ATARAID as its own category, or maybe we could call it "hardware assisted RAID" or "CPU assisted RAID", where you need a RAID chip on your motherboard or PCI card, which can do RAID 0 and/or 1, and typically has no onboard RAM. Just a suggestion. When one claims that the HPT370 or Promise FastTrak is "software RAID" its not entirely true, but neither is it valid to call it "hardware RAID". Ed
