Right, so looking at the slowness of my computer, you've all made me want to buy an SSD. I can't afford one at the moment but I may as well do my research and find the right one for me. I have a mid 2012, 2.5Ghx 13" Macbook Pro. The SSD I think I need is this one: 512GB Crucial m4 2.5-inch SATA 6Gb/s (SATA III) I definitely want to match the 500GB I currently have on my mac. However, are there any other options, preferably cheaper, but equally as good on performance? My other question is, should I wait for the M500 to come out? I've read up on SSDs, but I get very confused as a newbie so any basic information/ help that you could give would be appreciated!
