Yes the disk reads is a more realistic real world test :

/dev/sda5:
 Timing buffer-cache reads:   128 MB in  1.23 seconds =104.07 MB/sec
guf:~# hdparm -t /dev/sda5

/dev/sda5:
 Timing buffered disk reads:  64 MB in  5.84 seconds = 10.96 MB/sec

The above result is from the Ultratrak Tx8 (TX8000 now) with 8 60 Gigs IBM
deskstar 7200 rpm in raid 5. Kind of slow if you ask me.
