I am about to buy a new gaming PC based on Intel's Core i7 Sandy Bridge processor with ASUS SABERTOOTH P67 Motherboard (http/www.asus.com/Motherboards/Intel_Socket_1155/SABERTOOTH_P67/). I am used to "Seagate" hard drives and I can't understand the WD's Blue, Green and Black categories. On a forum I have read that WD hard disks are not for storage purposes but for performance purposes. But I want a hard drive which has both qualities like Seagate. Now that both Seagate and WD have both introduced SATA III 6 GBs 64 MB Cache I wish to make my PC future proof in terms of hard drives. I need a 1 TB hard drive which Seagate is not offering. If there is a WD with all the qualities of Seagate's Barracuda XT Desktop Hard Drives or even better and which is compatible with the above processor and motherboard kindly inform me.
