I've just went a purchased a brand new WD Raptor 74GB WD740ADFD and
compared my bonnie++ test I did against a Samsung 120GB 7200rpm drive
and the Raptor seems slow.
Here is the command I used to test
$ bonnie++ -s 1000
Here are the results from the Raptor

I'm not sure if I'm reading this right, but the Samsung drive looks like
it's killing the Raptor in Sequential Output and Input.
Has anyone got any ideas?
I'm just using the standard onboard controller (Intel ICH6), but I will
be using a 3ware 9500S-4LP in the end.
