Who ever thought that 8 gb of storage for app's on the Fire tv, should be shot. The latest Firmware for the Amazon Fire TV box, now allows you to connect USB storage. I now have my 300 gb drive, which is in a Startech USB/eSATA enclosure up and running. That box does need external power for the Fire TV to recognize it.

With just a SSD and SSD to USB adapter, did not need external power to use that. I do not think that Amazon has given a specific limit for external storage.

Now I can at least play Bard's Tale and some other games that use add-on Packs.
