Ok so, my 750GB hdd is almost full because I've split it into two partitions, one serves as my OS "drive", whilst the other as my backup partition. Now I'm thinking about huying two large hard disks to put into RAID 1 so that I don't have to keep backing up things onto different PC's and such. My current hardware is this: CPU: Core i7 920 @ 3.6GHz RAM: 6GB OCZ Gold @ 1700MHz HDD: Seagate 750GB 7200.11 + External USB 80GB (for music and stuff) Motherboard: Asus P6T Now my Asus P6T has these special RAID ports which they call Asus Drive Xpert: http://usa.asus.com/product.aspx?P_ID=QtpKQuERkuYw6trc&content=specifications It has two settings, Super Speed (RAID 0) or EZ Backup (RAID 1). I'm thinking about buying two Samsung 1TB F3's, and putting them in RAID 1 mode on those two ports: http://www.scanmalta.com/eshop/1tb-samsung-sata2-hard-drive.html Do you think that I'll run into some problem? Anyone has experience with such setups? Do you think that I should buy another 750GB 7200.11 and raid it with my current drive, and then buy a faster HDD as my OS drive? Maybe some 10k drive? What would you suggest?
