Bonnie vs hdparm

Trying to see how fast a hard drive is. Hdparm gives one number, bonnie
another. AFAIKT the bonnie numbers correlate to the hdparm disk reads
number, i.e 58/51 MB/sec for bonnie and 38.96 MB/sec for hdparm. This
is for a scsi cheetah drive, U320, on a U160 controller synced at
160MB/sec.

/dev/sdb:
 Timing cached reads: 684 MB in 2.00 seconds = 341.54 MB/sec
 Timing buffered disk reads: 118 MB in 3.03 seconds = 38.96 MB/sec
