Next generation of CinemaStar debuts
Hitachi proudly presents the next in the series of hard drives designed specifically for the role of storage in digital video and surveillance applications. The CinemaStar P7K500 hard drive provides customized features, high capacity and power efficiency making it an ideal solution for surveillance systems and consumer electronics (CE) devices like digital video recorders and set-top boxes.
Customized features support on-demand digital video solutions
An exceptional blend of audio/visual (AV) features fine tunes the CinemaStar P7K500 for digital video storage needs. Optimized to record multiple, simultaneous video streams, Hitachi SmoothStream technology is enabled to support the ATA-7 streaming command set, and SCT
provides time-limited error recovery and thermal monitoring capabilities. Because IT data and video streams have different throughput demands, AV-Zoning allows the definition of various error recovery procedures for predefined ranges of data blocks, or zones. This feature enables the system to effectively deliver critical system data and time-sensitive video content from a single drive. Other features that help tailor this drive for streaming video applications include Read Continuous mode, which helps manage error recovery for video streams, and Media Maintenance enhancements, which help prevent track wear-out from around-the-clock operation.
Power efficient for cooler operation and longer life
Leveraging six generations of power management technology, this new breed of video drive delivers best-in-class power management and thermal emissions. HiVERT technology was pioneered on 2.5-inch drives to help maximize battery life, but also works for this 3.5-inch hard drive to help minimize power consumption. These standard features on the CinemaStar P7K500 enable manufacturers to develop video systems that run cooler and require less power which ultimately leads to longer product life.
