http://forum.xda-developers.com – I have a USB-powered Western Digital hard drive that works with my N7 using an OTG cable. I was curious as to how heavy the battery usage would be when powering a spinning drive so I did a small test, playing the same movie from the hard drive and then from a flash drive. Here’s what I saw (I charged the N7 between tests, usage number from battery monitor measure of charge level): Stock 16GB N7 Play movie with MX Player Pro through Nexus Media Importer Duration of 1 hour, screen at 100% brightness Video: 832 x 352 1503 kbps h264 MP4 Results -- Sandisk Cruzer 64GB Thumb Drive, F (HowTos)
