The Deskstar 7K500 sustains the leadership momentum with a 25 percent capacity increase over the previous generation and double the capacity in the same space as a 250GB drive. A 2TB (terabyte) system can now be achieved with just four standard form factor ATA drives. This capacity milestone enhances system reliability by reducing the number of drives needed to support the most demanding applications. The Deskstar 7K500 is the second generation Deskstar drive to enable the host system to optimize storage of data. This is achieved by Hitachi's “Smooth Stream” technology which gives the host control over the drive's error recovery process. This important ATA-7 Standards feature fine tunes the Deskstar to capture long audio or video data streams.The Streaming Feature Set has features that enable an AV system to maximize performance of the disk drive.
