Better yet, use Serial ATA discs, which each get their own channel.
Plus the cabling is easier to work with. 3Ware has some neato
SATA cards, though these days motherboards often have 4+ SATA
ports. FC2 recognizes both the VIA and Promise SATA controllers
on my ASUS K8V, though I've only used the Promise (which is
supposed to be the better of the two). 80GB SATA drives are
*cheap*. My FC2 box boots off a SATA drive.
I'm probably go in the opposite direction with my personal machine
though and consolidate everything onto One Big Drive, in order to
cut power consumption and heat generation. I'm just waiting for
the Seagate Barracuda 8 series drives to ship.

Which is why I prefer to set up systems with several small
disks rather than one large disk.
More disks means that alternating accesses to different filesystems
(say the /lib directory in the root filesystem, and program
code in the /opt filesystem, and data in the /home filesystem)
won't necessarily result in large amounts of back-and-forth
disk movement.
With IDE controller cards, and small IDE drives both being
quite cheap these days, putting three hard drives each on
their own bus (ribbon cable) can give performance which
approaches that of SCSI performance (IDE manufacturer's
association still doesn't mandate the "elevator algorithm"
for fulfilling multiple R/W operations from/to a disk in
the most movement-efficient order possible, and which is
REQUIRED to be labelled SCSI).
