Good evening everybody, I'm very new here but have done a decent amount of searching before coming to ask you guys this question. I bought my 2014 11 inch MacBook Air 128GB back in August with the intention of upgrading the SSD at a later date. I am beginning to run low on space on my hard drive. Jetdrive's MBA SSD Upgrades confirm compatibility only with the 5, 1 and 5, 2 models. Is anybody aware if there is an actual hardware change between 5, 1/5, 2 and 6,1 which would prevent compatibility with these upgrades? Thank you in advance and if anybody does have any testimonies please let me know!
