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?
Feature s and B e n e f i t s
Feature / Function Benefits
Performance High interface transfer rate Faster system boot-up
Quicker screen refreshes
8MB buffer size (80GB SATA) Faster data processing
“Smooth Stream” technology Improved performance for AV storage applications
Capacity 80 GB and 40 GB Most popular capacity points
Reliability Low power mode Cooler system operation
Enables lower cost power supply and fan
Head load/unload Protects disk during non-operation
Reduces power during idle periods
ECC and CRC protection Data integrity enhanced throughout drive circuits
Optional low-power mode Further reduces power requirement
Reduces system heat / cooling requirement
Internal thermal sensor Improves data integrity
Acoustics Low acoustic levels Quieter system operation
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.
