debianoak:/home/nbp# hdparm -tT /dev/hda
/dev/hda:
Timing cached reads: 1192 MB in 2.00 seconds = 595.20 MB/sec
Timing buffered disk reads: 6 MB in 3.24 seconds = 1.85 MB/sec

That looks reasonable to me - very fast from the cache and a lot slower
when it has to be buffered (on the hard drive, presumably). But, what do I
know!?
That is not even close to reasonable. I have never seen buffered reads THAT
bad.
Timing cached reads: 1316 MB in 2.09 seconds = 629.02 MB/sec
Timing buffered disk reads: 158 MB in 3.02 seconds = 52.25 MB/sec
That is what I get when I run it on an HP d325.
Do this too if you want some more information on your drives.
hdparm -I /dev/hda
