"hdparm -t", som Keld nævnte, virker
da fint på SCSI drev:

# hdparm -t -T /dev/sda

/dev/sda:
 Timing buffer-cache reads:   128 MB in  0.25 seconds =512.00 MB/sec
 Timing buffered disk reads:  64 MB in  1.47 seconds = 43.54 MB/sec

og (næsten) på SATA drev:

# hdparm -t -T /dev/sda

/dev/sda:
 Timing cached reads:   3824 MB in  2.00 seconds = 1911.88 MB/sec
HDIO_DRIVE_CMD(null) (wait for flush complete) failed: Inappropriate 
ioctl for device
 Timing buffered disk reads:  164 MB in  3.00 seconds =  54.59 MB/sec
HDIO_DRIVE_CMD(null) (wait for flush complete) failed: Inappropriate 
ioctl for device
