    Looking at the 13" it has an added benefit I see which is the SD card slot. I am wondering if the speed of this (given a fast card of course) can act as a second hard drive and thereby compensate for the relatively small 128Gig SSD?
    I know it is way slower regardless than a 256 SSD but significantly cheaper too...;)

    I was thinking data files, media etc. Or would this be too slow compared to like an external USB based HD? I would think it would be faster but I don't know.

    There is another thread already, use search:

    Short version: Not fast enough, reliability issues, doesn't fit flush, way more expensive in terms of storage space. ($100+ for 64GB)
