when I bought mine, I selected the 320Gb 7200rpm, and never look at 500GB as I always said to me that, for big space, NAS Server or External 1/2Tb would be the best option, as when I'm moving, I really don't need that much space, only when I'm at desk.

So, instead, I upgraded to a 240Gb SSD from MacSales (OWC), and ... WOW, what a speed! what a thrill to use this drive! no sound, no moving peaces, faster as you can dream.

See here a normal drive (HHD) versus an SSD booting up

image below blue drive is the SSD drive, outside drive is the WD Scorpio Blue 320Gb

then I also bough a 2,5'' Bus powered enclosure to put my 320Gb native drive as now I use to keep my recent stuff including photos.
