How? The BIOS is doing the reading from those disks if it doesn't understand how to use the redundancy there is a problem. I would be surprised if a "firmware" RAID system (like say a Promise FT100TX2 or FT2300) would be any slower than using those disks on a comparable but non-RAID controller. Once the OS starts it is its responsibility to maintain the metadata but it should still be able to get a good speed. I would say the requirement to sync the metadata to disk will slow it down but a pure software RAID system should do the same or risk array corruption. -- Daniel O'Connor software and network engineer for Genesis Software - http://www.gsoft.com.au "The nice thing about standards is that there are so many of them to choose from." -- Andrew Tanenbaum GPG Fingerprint - 5596 B766 97C0 0E94 4347 295E E593 DC20 7B3F CE8C
