I guess you could keep your linux OS on /dev/hda and use the 5 x 9.1Gb
drives in a RAID 5 array of about 36Gb. However, if you really need lots
of space with redundancy for your /home, I'd invest in some 160Gb+ IDE
drives for a RAID 1 or RAID 5 mirror, and use the SCSI drives for a RAID
5 mirror for /, /boot and swap. I'd use 3 x 9.1Gb disks in the array
with 2 x hot spares. Fast and with redundancy protection, but probably
pretty noisy too.
