If your Xbox 360 needs more storage space for downloaded games, movies and other content, a new, bigger hard drive is on the way. The new HDD will connect to your game console easily. The drive is also priced reasonably at $129.99 (USD) MSRP.
Upgrading the hard drive in your Xbox 360 or PS3 can get pricey. The upcoming Datel Space Dock lets you expand your storage by as much as 1TB using an off-the-shelf hard drive.
There are two versions coming out, one for PS3 and the other for Xbox 360.
