So I purchased a 128GB ssd off ebay to put in my 64Gb model. They look identical, the only way the tech would be able to tell is go into system settings. I have a genius bar appointment, would you guys exchange the 128gb model with the 64gb model just to be safe?
Technically, the SSD is considered non-user upgradable by Apple, but unless you are taking it in for a repair of the SSD or the logic board, chances are it won't matter.
I would change it back if you ever need to bring it into service. Some techs are really anal about this stuff, others don't care at all. I remember when I was a genius and if someone did an upgrade like a hard drive to a non-unibody and I could tell they made a mess of the machine, I'd deny service. If it was done and I otherwise couldn't tell, I let it slide. Official policy is "not covered period".
Fair enough answer. Ill change it back when I go to service the trackpad. They couldnt tell as replacing the SSD in the MBA is so easy.
