Not in my experience. My 6.6TB software RAID 6 array on 16 disks using
JFS takes only a few minutes to fsck, and the 1.6GHz Xeon is nowadays
hardly state of the art (especially since software RAID does not use
more than one core).

Frontend/backend:	P4 3.0GHz, 1.5TB software RAID 5 array
Backend:		Quad-core Xeon 1.6GHz, 6.6TB sw RAID 6
Video inputs:		Four high-definition over FireWire/OTA
Accessories:		47" 1080p LCD, 5.1 digital, and MX-600
