My mom's 2010 MBP (7,1) hard drive has basically failed. She's looking to get a replacement for around $115 at the most. I'd like to find her a decent SSD, since I know those are faster. I found one on Amazon: the SanDisk SDSSDHP-128G-G25. 128 GB is plenty for her, but idk whether this will work with her model. I've heard there's an issue with 3Gb/s and 6Gb/s something or other, but I'm not sure as to the details since I've never replaced a hard drive before. Optionally, does anyone have any other reliable and fast hard drives they recommend? Hybrids maybe if you know of any in that price range.
