I was asked what I used to extend my Retina Macbook storage. Mine still has an SD-card slot so the sit flush solutions below work fine.
I could have used USB-3 to micro-SD card adapters that sit flush.
There are no USB-C to micro-SD adapters that sit flush, so they do not work for more modern Retina MacBook devices.
