I need advice about Mac SSD compatibility


I'm trying to figure out whether the SSD part number 655-1816B is compatible with MBP 13" Early 2015. I know according to iFixit, the 655-1816A is compatible. Is there much difference between the 2 revisions. It seems very tricky to navigate the various identifying numbers and their compatibility with the various models. Both versions seem to share another identifying character string, which is THNSN2128GSPS if that helps. Hopefully someone can shed some light on this, as it has me pretty much beaten.

Thank you in advance,

The best way I know to figure this out is to hold it up to the screen and count the pins and compare it to the pictures.

Thank you for your response, however it’s not a question of them physically fitting, but whether or not they are compatible or run optimally eg the transfer rate may not be well matched etc. I know that they will physically fit & have the correct number of pins, but from what I understand this doesn’t necessarily mean they are suitable. It seems to be very difficult to be sure from what I have researched. I couldn’t find any definitive guide; it would be great if there was one.
