I have the macBook pro 15 in my sig. Can I buy a hdd tray on ebay for the DVD drive and put in another SSD in addition to my current SSD and then run them in RAID 0? Will my motherboard support that? If yes, how do I tell it to run it in raid 0? If yes, do I have to use the exact same SSD (because it is discontinued) or can any 2 SSDs work? Or do they have to be the same size?
