Guys,

	I've heard that hdparm does not run on scsi drives.(SATA included)

I've tried to use hdparm anyway, and it gave results. But the results
are seriously _out_of_this_world (for me).

Can anyone validate these?

/dev/sda:
Timing buffer-cache reads: 2416 MB in 2.00 seconds = 1208.18 MB/sec
Timing buffered disk reads: 444 MB in 3.02 seconds = 146.90 MB/sec


Compared to my Laptop's 80GB (Hitachi) PATA (5400rpm)

/dev/hda:
Timing cached reads: 1492 MB in 2.01 seconds = 742.40 MB/sec
Timing buffered disk reads: 112 MB in 3.04 seconds = 36.85 MB/sec
