Alright so I now have all the HDD's I could ever need for my rig. The list is as follows 2x74gb Raptors 3x500gb Seagate Barracudas 1 WD x 320gb HD Now my question is, What do I do with them? The raptors are easy, I'll raid 0 them and install apps/windows on them But the 3 500's and the 320? I figure I have a few options. 1) Raid 1 two of the 500's for security and place important files on these two HDD's and leave the other 2 (320 and 500) for other documents 2) Buy another 500 and ditch the 320gb/ put it in a usb cage and throw it in my car and run 2 500gb raid 1's and have 1 terabyte of raid 1 security 3) Run a crazy raid setup with #2 and have 2 raid 0's mirrored (Is that raid 5?) 4) I dunno What should I do? The 320gb drive is killing me here. I know I have enough space, but I hate that my drives aren't matched. It's like the ugly duckling. Oh and I also run a Sata DVD drive so I'm going to need a Raid PCI-E card. Should I get one and plug my raptors into it? Or should I plug the storage HDD's into it?
