My values on my 1.4Ghz Dell are:
/dev/hda:
 Timing buffer-cache reads:   128 MB in  0.61 seconds =209.84 MB/sec
  Timing buffered disk reads:  64 MB in  2.36 seconds = 27.12 MB/sec

  The second value is fairly good. We have machines with values as low ad 2-3
  MB/sec of disk reads. In my opinion the first value is more realted to the
  speed of the processor and the spee4d of the cache. As you can see with a
  1.4GHz processor it is much faster than your values.
