while it takes a minimum of 6 disks, we've had great luck with RAID 50. Two separate RAID 5 arrays (fast read, moderate writes) that are then placed into a RAID 0 (fast read, fast write). you lose 2 drives worth of space, but lord it's fast and the data is mirrored. Not sure if you can do the whole thing in software. I use two 3Ware 9650SE cards to do the RAID 5 and I do RAID 0 in software. Jason www.cyborgworkshop.org John J.
