} 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).

any journaled filesystem is easy to fsck, its the rebuilding a drive that
takes a while these days. 20 drives would take a while to init and or rebuild
if you had to. not like days of course but unless you crank up the cpu/bandwidth
limits way up it would be 10+ hours.
