From the basic specs it does appear to be a workable SSD replacing your current HDD. Its an older generation so its SMART services are limited and the I/O speed is not the greatest. Review this review Kingston-A400-240GB If you jump to this view you’ll see the better drives SSD BenchMarks. Personally I would stick with either Crucial or Samsung 2.5” SSD’s as they are more aggressive in supporting the newer version of SMART and have great performance. Yes, they will be a bit more but on the long haul are a better bet.

thanks for this. i just checked compatibility on the Crucial website for a 250 SSD and it said it was incompatible. is this because apple dont officially allow you to upgrade the HD or is it actually incompatible? Obviously i want to be sure i buy a compatible drive!


I know iFixit has checked out the Crucial drive they offer so I would recommend you go with that one.

This gets into the version of SMART services the drive supports. You system needs the current version.

Then I guess you'll need to go with Samsung 860 EVO SSD.
