This is from Dell PERC 4/Di with two 136 GB disks (U320 @ 10000 rpm)
in RAID-1:

# dd if=/dev/rld0d of=/dev/null bs=64k count=5000
5000+0 records in
5000+0 records out
327680000 bytes transferred in 5.044 secs (64964314 bytes/sec)

# bonnie -s 500m -d /var/tmp
Machine    MB K/sec %CPU K/sec %CPU K/sec %CPU K/sec %CPU K/sec %CPU
           500 59505 40.5 43430  8.4 44081 13.2 118949 99.8 752250 100.0


I really like this compared to my "old" server's poor 13 MB/s [1].
