Apple Silicon Soldered SSD Upgrade Thread

Has anyone been able to upgrade a 256gb M4 MacBook Air NAND yet? Unable to find out which chips I need to get

I've done multiple m3 airs and had no issues using the K5A8 for the 2TB upgrade. However I keep running into issues with the m4 air's.

I suspected its an issue I was causing but kept having the same after 2 attempts. very frustrating working on this particular machine!

I'd used the SDSFGKLKH Nand but would suggest trying to use the K6B2 instead as they have a smaller footprint on the board and the air uses 01005 sized components around then Nand instead of 0201's. unfortunately the price isn't great at the moment on those (on Ali express)

m4 air requires K8A5 nand chip for the 2TB Config

well this is a pleasant surprise, I had no idea that is what I should have been using all along! I shall give that another try as I have some K5A8 chips on hand! thanks for the info.

Beware, it is K8A5 not K5A8…
K6b2 / SDSF / K5A8 are not working with M4 MBA - from my experience

ahhh I was thinking that was tooo simple and easy. I assumed there was a typo and it was supposed to be K5A8.

but now its back to the drawing board to source some of these chips.... open to recommendations


thanks of the additional clarifying response pal!
