Capacity Leadership
The Deskstar 7K500 is the second generation
Deskstar drive to enable the host system
too ptimize 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
