Best Wi-Fi mobile storage devices(Updated May 15, 2013 2:55 AM PDT)
It's really a shame that the iPad, or any tablet or smartphone for that matter, comes with such a limited amount of internal storage -- usually around 64GB or less.

This is the reason a wireless storage expander is a must for savvy users who want to carry their entire digital library around with them. You'll find the best devices of this type currently on the market here.
