I would like a lot of storage for music and videos. For the price of a 32gb microSD , you only. can get a 16gb M2 card. I would love to be able to swap out cards if M2 cards were not so costly.
Given those sizes, it might be more appropriate to look for some kinda shim. Or maybe a mod to resolder a microSD slot into a PSP go, which would be epic if it were possible.
the best thing is make an effort and buy at least one 16 giga m2 even if have some adaptor for micro sd you shoud consider the fact of psp go work on magic gate card suportable too
