well, here's one from a production machine. There were disk writes
during the test, so one can assume it performs even better on idle machine:
# atacontrol list
ATA channel 1:
Master: ad2 <MAXTOR 6L040J2/A93.0500> ATA/ATAPI rev 5
Slave: no device present
# dd if=/dev/ad2 of=/dev/null bs=1024k count=1024
1024+0 records in
1024+0 records out
1073741824 bytes transferred in 25.935189 secs (41400964 bytes/sec)
The hard-drive is an old 40G Maxtor. Propably 7200RPM.
