"The Seagate FreeAgent GoFlext Ultra-Portable hard drive is more than just a portable 2.5" SATA HDD. key to the system's brilliant usefulness is that Seagate designed this hard drive to interface with a series of modular cable interface adaptors, docks and a media player. It's what you'd call, really very flexible. But that's not all... Seagate made the core FreeAgent GoFlex hard drive so it will slot into the companies' TV HD Media Player product, interfacing via the drives native SATA port. Sliding a hard drive into the Media Player is a quick and simple way to open up access to hundreds of gigabytes of digital content on the spot.
