Yes, you want the "multi-disc" driver "md".  Go into the kernel config
(make menuconfig) and check it out in the block devices section.
It includes RAID 0, 1, 4, and 5 I believe.  I used to use RAID 0.
Rob is using RAID-5.  I eventually switched to a hardware RAID
implementation (good for preventing incredibly large reboot times
required after a crash -- raidcheck followed by file-system check).

Well, there's a few IDE RAID boards that give you RAID 1 on a pair of
drives.  They're around $200.  The Mylex SCSI boards are great, but they
start at $600 and go up from there.

It depends on what you consider "inexpensive".
