I am a student networking with wireless tech. My old p4 won't handle virtualization very efficiently. So I ordered what can with under 400$. I am an intel man but I went with the amd 8120 and an asus 990fx chipset. Issue arise at I have a bunch of old drives. I am not working so money will be an issue. I have not even purchased a video card yet. I have a ton of externals for back up so I am not worried about redundancy. I found 2 laptop drives and I have a 500 gig drive. The 2 laptop drives are 160gig and 320gig. What the best raid configuration ? I was thinking about raid 0 + 1. Put the 2 laptop drive in raid 0 and the 500 gig for parity or what ever they call it. As I can afford it I would like to replace the mechanical with 2 ssd drives. I do have a separate raid pci controller card. As I get upgrade parts can I pull drives out of the array and eventually run 2 ssd drives in raid with external back ups?
