I have managed to get my hands on a ridiculously cheap Crucial m4 256GB SSD. For some time now, I have wanted to replace the optical drive in my 4 year old MBP with more storage as I rarely use the optical drive and could use the extra disc space. My question is this; I know an SSD on a relatively old machine like this is a little overkill. I know it will increace perfomance, but i don't know how much the isnternal components will be able to utilize the speeds of the SSD. -Should I sell the drive (the box is sealed, so I can get a fairly good price for it) and buy an ordinary 7200rpm hard drive and save a little more than 100$ or should I just go for it and install the SSD?
