I want to add two 500 gig drives to my existing 250gb one and was hoping for some advice from someone more knowledgeable than me on the subject (thats most people). I've got a Sony Viao VGX-XL301 with a fast filling up 250gb SATA drive. It's got 2 free bays so I'm going to fill them up, so my questions are: - Will SATA 2 drives work in my machine (I've done a bit of looking around and I think they'll be OK but just to be sure)? - Are some drives less noisy than others? What would you recommend? I've been considering 2 x Hitachi Deskstar T7K500 500GB SATA2 16MB 7200RPM 2 x Samsung SpinPoint T166 500GB SATA2 16MB 7200RPM 2 x Seagate Barracuda 7200.10 500GB SATA2 16MB 7200RPM or 2 x Western Digital Caviar SE16 500GB SATA2 16MB 7200RPM mainly because I can get a deal on them here http://www.komplett.ie/k/kl.aspx?bn=10096 , what is the better and more reliable make? - When I add these 2 new drives can I get all 3 to act as one? My main concern with this is for media centre use i.e. I want to keep putting movies in the folder I'm currently using. Thanks.
