Hello there, I have a 2015 MacBook air 13" (A1466) with a 128GB SSD but i need more storage. On the internet i saw a 256GB SSD from a 2012 MacBook air 13" (A1466). Will the SSD fit in my 2015 MacBook air? Or there are limitations?
No it won’t fit, you can use SSDs from 2013-2015 in the 2015 models, although the 2015 ones are slightly faster (average user will not notice a difference)
