Data centres that need fast access to data in Tier 2 environments need look no further. The HGST Ultrastar 7K2 delivers fast data access in capacity optimized, enterprise-class storage systems. Enhanced RAFF technology in the 7K2 includes sophisticated electronics to monitor the drive and correct both linear and rotational vibration disburbances in real time - especially helpful in multi-drive arrays and rack-mounted systems maintaining high read/write performance. Designed to handle workloads up to 550TB per year, the Ultrastar 7K2 delivers up to 2TB of affordable storage capacity for high-intensity applications in enterprise class environments. Data centres face growing pressures to store more with flat-to-shrinking budgets. Keeping systems operational for as long as possible to maximize investments can be an effective part of the strategy, but supporting those legacy applications becomes even more challenging as drive technologies move to next generation formats and interfaces. The 7K2 has a SATA 6Gb/s interface and native 512-byte (512n) sector size to provide consistent, high performance and compatibility with legacy data centre applications. Dual-stage actuator technology provides a head positioning system that improves positional accuracy over the data tracks, enabling data to be written to and read from the drive more reliably. Trust HGST to deliver storage options that allow data centres to get the most from their hardware investment.
