My reasons for using the largest block size was more of the space
efficiency -- the fs typically holds no more than 20 files in 10 directories,
but the smallest file is 1Gb in length. This is also why I chose ufs1 (-O1)
over ufs2 -- we don't need ACLs on this filesystem.
I never benchmarked the speed on the single drives, other than to compare with
my RAID5 array (which puzzlingly always loses to a single drive, but that's a
different story).
Thanks,
