after -c 3:

/dev/hda:
  Timing buffer-cache reads:   1912 MB in  2.00 seconds = 955.19 MB/sec
  Timing buffered disk reads:  110 MB in  3.04 seconds =  36.18 MB/sec

It's the Travelstar 5K80: http://www.hgst.com/hdd/support/5k80/5k80.htm 
  It's also really quiet, much quieter than my old Dell Latitude D600's 
Travelstar (40GNX, I think - also a 5400rpm Hitachi with 8 MB cache but 
ATA-5 only and without the "noise reduction using a VCM Damper" this 
5K80 has).  They also claim that using "adaptive formatting" the 5K80 is 
   about 10 MB/sec faster than a 40GX, which seems to be true (got about 
26 MB/sec with the 40GX)
