Apple holds their card quite tight so I doubt anyone can answer what some of the numbers on the SSD. Keep in mind there are the Apple P/N’s and then the manufactures P/N’s and the lot number and lastly the logic board its self has a number too!
Buying off stuff from Amazon, eBay or AliExpress can be a bit of a gamble. I would recommend going to a specialty store that specialize on these custom SSD’s I would recommend BeetsTech as a good source.
