A/V Streaming Feature Set

The Deskstar 7K80 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 record and play multiple standard definition and high definition video streams.

Why Serial ATA 3.0Gb/s?

>3.0Gb/s (300 MB/s) interface data rate

>NCQ (native command queuing)

>Staggered (delayed spin-up
