I'm looking for an SSD to speed up my wife's aging 13" MacBook Pro (Core i5 2.5 13" Mid-2012). I've never replaced a hard drive with an SSD before, so I'm not exactly sure what to look for. I don't need the highest end drive as we'll likely be replacing the computer in a year or so...I just need something to get her through until then. What do I need to look for to make sure the drive is compatible? Can you recommend any ~250GB drives that can be had cheap? How much should I expect to spend? I've seen a variety of prices from $45 to over $100. Thoughts? Thanks for your help!
