The Underscore Archives

Hi All, I am not really a hardware buff but seem to be getting limited 
joy finding a decent 2.5" SATA 250GB 7200RPM drive to add to my 
Alienware laptop which currently only has a 120GB drive [1]. It seems 
that there are plenty 3.5" running at 7200RPM but when you find a 2.5" 
of equivalent size the speeds drop to 5400RPM - is there a reason for 
this? Can anyone recommend a suitable drive Fujitsu or WD preferred but 
will take on board any recommendations? Up until now I have used Fujitsu 
drives which have proved very reliable but my portable one is about to 
crap out on me and for the minute I am going to chuck another drive into 
my laptop. The 2.5" Fujitsu I would have gone for [1] doesn't seem to be 
available until end of May.

Any recommendations/advice would be appreciated.

Cheers, Simon
