www.hardwarezone.com? Hitachi 7K400 Review. First review of the incredible 400GB drive from Hitachi.
Seems like it is super for AV applications. Main issue is that it will run *hot* with 5 platters of 80GB each. Cost is about $400 in limited quantities and there is also a 400GB DVD recorder called the Hitachi MS-DS400 that uses it for consumer electronics applications.
