New York - Seagate today introduced its first 3TB external hard drive, the FreeAgent GoFlex Desk.

The drive is available immediately for $249.

The drive can attach to a PC via a USB 2.0, 3.0 or FireWire 800 port.

Seagate said home-storage demands will rapidly grow in the coming years. The company cited a Parks Associates report that stated household digital media requirements alone will hit the 900GB level by the end of 2014, driven by HD video and Blu-ray.
