Bulk data encryption
Hitachi's bulk data encryption uses a miniature processor directly on the hard drive to encode and decode the data, which frees the host computer's CPU for other tasks, enabling users to protect data without impairing system performance, effectively putting data 'under lock and key'
SMART command transport protocol
Our latest drives have been designed to improve data integrity and meet the deadlines in streaming applications. The SMART command transport protocol minimizes disruptions in stream delivery by adapting buffer management behavior and error recovery timing to match the characteristics of typical streaming applications.
SmoothStream™ technology
Because AV systems play and record streams of data, they place very different demands on a hard drive from traditional IT and computing applications. If the stream is interrupted, audio or video information can be lost, creating an unacceptable delay. Our patented SmoothStream technology, which delivers an integrated set of features and functions, helps Hitachi hard disk drives perform their best in audio/video applications.
Hitachi SmoothStream technology enables a host device to control the drive's error recovery processes. This feature tunes the drive to capture video data streams on a command by command basis, allowing integrators to mix different AV and IT applications on the same platform.
AV-Zoning
Some of our drives offer a special feature called AV-Zoning, which allows data recovery procedures to be defined differently for multiple partitions on the same drive. In this way, critical system data can be differentiated from time-critical video content, which may not require the same stringent data recovery measures. As a result, AV-Zoning helps ensure smooth video experience.
Native Command Queuing
Native Command Queuing (NCQ) helps to increase performance of SATA hard disks by allowing the individual hard disk to internally optimize the order in which received read and write commands are executed. In Hitachi GST drives which feature NCQ, fast data transfer rates and up to 16MB cache are made possible.
