Hmm, the IDE drive in my notebook beats that!

defter:~# hdparm -tT /dev/hda 

/dev/hda:
 Timing buffer-cache reads:   128 MB in  0.55 seconds =232.73 MB/sec
 Timing buffered disk reads:  64 MB in  3.29 seconds = 19.45 MB/sec

This is an IBM a30p, with a 5200? RPM 2.5" 48 GIG drive.

So what are we concluding from this?  I choose to conclude nothing
of major significance.

cheers,
