Hello, I just upgraded the HDD to an SSD in a 2010 macbook pro. Everything is working fine (or not?). I ran the "black magic disk speed test" to see if I got the results that I should get. To my knowledge, the write speed should be ~400 Mb/s and the read speed should be ~500 Mb/s. I'm only getting 257 and 270?? Is something wrong, and is it possible to fix?
