Ok so I just received 2 used OCZ Vertex 2 120g SSDs. I know they are old and outdate but I got a real good deal on them and cant afford the new stuff. I am attempting to install them in raid 0 for my boot drive and my games. I have completed the raid, the install of windows 7 and what not but for some reason it is showing I only have 148g of space on the raid. Is this normal?
