But the stuff installed off the CD-ROM generally is not what you need
performance for. What you need performance for is things like news spools,
database data sets, etc. That's what I'm using a RAID-0 for at Sabine --
it really speeds up running reports against multi-megabyte data sets.
Any normal SCSI drive has more than enough performance to quickly get into
memory those programs that you normally run. Once it's in memory, who
cares how fast the drive is? It's just for things like news spools etc.
that something like RAID-0 really shows its stripes.
