Hitachi Deskstar E7K1000 HDE721050SLA330 - hard drive - 500 GB - SATA-300

The Deskstar E7K1000 delivers value to the enterprise and innovative technologies like Rotational Vibration Safeguard (RVS). Systems with multiple drives installed are at risk for rotational vibration disturbance, which results from simultaneous operation of neighboring drives. To mitigate any adverse impact on system performance, Hitachi-patented RVS technology works to counteract this disturbance ensuring drive performance and data integrity. With a SATA 3Gb/s interface which utilizes the same physical connector as Serial Attached SCSI (SAS) drives, the Deskstar E7K1000 is ideal for use in mixed-drive enterprise environments. The Deskstar E7K1000 hard drive provides an exceptional blend of power efficiency and performance making it an ideal solution for power-conscious enterprises. Leveraging seventh-generation power management technology, as well as power-saving innovations pioneered on the popular 2.5-inch line of notebook hard drives from Hitachi, this breed of drive delivers best-in-class power management and thermal emissions to help manufacturers meet energy compliance targets and extend drive life.
