Capacities represented may not be combined. Designed for on-demand digital video solutions An exceptional blend of audio/visual (AV) features fine tunes the CinemaStar 7K1000.C for digital video storage needs. Optimized to record multiple, simultaneous video streams, Hitachi SmoothStream technology supports 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 to enable the system to effectively deliver critical data and time‑sensitive video content from a single drive. Other fea‑ tures 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, preventing track wear‑out from around‑the‑clock operation. Less power for cooler operation and longer life Leveraging eighth generation power management technology, as well as power‑saving HiVERT innovations pioneered on Hitachi 2.5‑inch notebook drives, this new CinemaStar hard drive provides up to 18% idle power savings over the previous model, delivering best‑in‑class power management and thermal emissions. These standard features on the CinemaStar 7K1000.C enable manufacturers to develop surveillance systems and home digital video recorders that run cooler and require less power which ultimately leads to longer product life. Robust technology for a more sustainable environment All CinemaStar products are enhanced with silent‑seek acoustics to deliver bedroom‑quiet operation, and the Hitachi patented load/unload ramp mechanism that helps prevent disk wear and protects the disk during non‑operation. The CinemaStar 7K1000.C demonstrates our ecological leadership with its halogen‑free design and power‑efficient operation. These features helped qualify the drive for Hitachi’s EcoTrac classification, identifying products that minimize environmental impact in areas of design, manufacturing, operation and disposal.
