You can get faster performance with 3 smaller drives raided into one
volume for speed. You'll want them to be SCSI and have a decent raid
card.
Our real server has 6 18gig 10,000 RPM drives at RAID level 3. RAID 0
is good if you don't have the money for the redundancy but want the
speed boost and single volume. Raid 3 and 4 have striping with parity.
4 is good if you are dealing with huge MPEG files and surestream files.
RAID 3 is better with smaller files. Both 3 and 4 have performance
hits on writes because of the parity, but its saved my butt twice in the
last two years because the system stays up and continues to have access
to data even after a drive fails.
Oh, cacheram is worth the money on the raid controller. Especially when
you've got a small group of files that are accessed a lot more
frequently than others. My system has 128meg of on-board sdram on the
controller and our most accessed media files come up incredibly fast
even when there are a lot of people accessing them at once. It also
helps when you are writing large files since the OS doesn't have to wait
for the data to be dumped to the drives and the parity to be written.
Its great when doing massive vidcaps.
Of course, our capture box actually has 2gig of ram in it so it can
vidcap raw full-frame AVI straight to memory and write it to disk at its
leisure.

Tori-
Based on my experience, using one large hard drive is much easier that
using
three smaller drives. Unless you are planning to mirror the drives in
any
way, my advice is to invest in one large hard drive instead of three
smaller
ones. This would also eliminate any problems involving conflicts. I
recommend going with the one large hard drive...
