Seagate's plans for a rare truly cable-free hard drive were uncovered through an FCC filing this week. Its GoFlex Satellite would have not just 802.11n Wi-Fi to serve storage on the local network but would have its own battery to operate completely cable-free for hours. An iOS app, GoFlex Media, would let iPad, iPhone, and iPod owners stream music or videos directly from the drive, presumably as a way of giving access to a much larger media library while travelling.
