I'm using Class 10 Gskill 64GBx2 I bought from newegg.ca for $30 each. That Sandisk is double the price per GB!
I'm not sure I'd be comfortable paying an extra $131 convenience fee for having 128x2 vs 64x4.
That's also a risk failure of 120GB+ at once. Wouldn't it be better rotating 64's?
Would be, but I'm lazy and I like to spend money . I already have 64gb cards but I can use them in my camera gear as well so it's a no brainier for me.
