Adjile RAID box, 5 Fuji 4GB disks, RAID 5, verify off (on cache), 8MB cache.
P5120, 64MB RAM, FBSD 2.1 stable (supped 1/21), Adapter 2940UW, tag enabled.
Unfortunately, I was not able to re-newfs this box, and as such, the file
system was moderately filled (news partition). When fsck'ing and running
iostat, sps bounces between 10k and 13k, which is pretty quick.
