Best Wi-Fi mobile storage devices(Updated December 10, 2013 1:55 AM PST)
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. That includes the operating system and apps; the remaining space for digital content is even less than that. 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.
The SanDisk Connect Wireless Media Drive makes up for its slow USB speed by offering an excellent feature set and an SD card slot that will make most casual mobile users happy, especially photographers.
