I currently use 2 Seagate hdd's, one is 160gb and the other is 250gb. The 320 was stock on my 2004 model Gateway gt5404. I use the stock drive for the usual Windows Vista 32, my various programs and games, iTunes music. I actually filled the 320gb hdd and a friend gave me their old 160gb since they purchased a new computer. I'm currently collecting pieces for a new gaming build, so a new 1TB drive would be an amazing upgrade to what I use now.
Thanks Linus and WD for offering such awesome giveaways!!!
