With the addition of more and more great high-end games to the Amazon Fire TV’s app library, the number one complaint from users has always been the device’s lack of expandable storage. The Fire TV’s 8 GB internal storage fills up in no time when popular games like GTA: San Andreas and NBA 2K15 require nearly 3 gigs of space each. Good news, because Amazon has heard your complaints and the Fire TV development team is finally addressing the issue in the next software update.
A trusted source at Amazon tells me the theme of the next Fire TV update is “connectivity”. He says Amazon is “finally going to put the Fire TV’s USB port to good use”. He didn’t explicitly say it, but I’m interpreting that to mean the next software update will add official support for expanded storage to the Fire TV via the device’s USB port. I expect you will be able to install and run apps from a connected drive. I do not expect the same functionality to be added to the Fire TV Stick since the micro-USB port on the Stick is used to power the device.
