	I've heard need for this in early AV systems, but disks are fast enough 
where this isn't quite an issue. If your gaming rig is 
swapping/reading/writing - and not keeping up during the action - 
there's something seriously wrong with something. The performance 
increase in something like that should be pretty slim - simply using 
faster disks, an SSD, or using seperate disks and controllers for 
OS/apps/data/swap seems like a better choice to me.

	(Early days of AV, we were *lucky* to sustain 5MBps from an array of 4 
SCSI disks. I once cooked a burrito on a late '90s-model Seagate Baracuda.)
