Even on a raid 5 array, I'm sure that the processor will be waiting for the
disk I/O. There is alot of it, after all.
Is it a problem? Naw...
Will it process messages faster with separate disks, and even separate disk
controllers?
I'm bettin it will.
But when it comes down to it, are you more limited by bandwidth or disk i/o?
Fix one bottleneck, you'll make another.
