that's a little bit harsh dave :-)

some advice/things to check

o are you using hardware raid in your 2400 ?

o how much memory do you have in it ? (memory helps, even with
  write caching)

o if you are using the onboard raid, what stripe size did you use ?

o how poor is the performance on writes ? Megabytes/sec ? Kilobytes?
