today’s demanding computing needs.
Why Serial ATA II 3.0Gb/s?
The newly approved SATA-II specification has
standardized three important features:
>
3.0 Gb/s (300 MB/s) interface data rate
>
NCQ (native command queuing)
>
Staggered (delayed) spin-up
The 7K80 provides all of these enhancements
to enable faster data access and better power
management to the system. The drive is also
backward compatible for those wishing to
upgrade their storage of SATA 1.0 systems.

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 capture long audio or video data streams..
