I read up before on using a 128GB SD card for my Gateway when i was thinking of upgrading from my 16GB card. It seems like quite a lot of people encountered problems getting 128GB to work properly. You can probably do a search on it in Google to read what those people encountered. In the end, i got for myself a 64GB card which didn't seem to work.... Then i bought again another 32GB one which worked fine. So i'm on the 32GB card for now...
Can you link some sources please?
