HGST Ultrastar HUA721010KLA330

The Ultrastar A7K1000 features a 3 Gb/s SATA interface supporting key features in the Serial-ATA specification including Native Command Queuing (NCQ), staggered spin-up and hot-swap capability. The Ultrastar A7K1000 allows for configuration scalability and with the same physical connector as Serial Attached SCSI (SAS) drives, it's ideal for use in mixed-drive environments.
In multi-drive environments, rotational vibration, which results from the vibration of neighboring drives in a system, can degrade hard drive performance. To aid in maintaining high performance, the Ultrastar A7K1000 incorporates enhanced Rotational Vibration Safeguard (RVS) technology providing up to 50% improvement over the previous generation against performance degradation, leading the industry.

  1. Hitachi HDD 1 tb 5 Star Review

    Posted by on Aug 8th 2017

    Tested ok with Hitachi HDD utilities, seem to work ok

  2. Working perfectly 5 Star Review

    Posted by on Feb 13th 2017

    The disk came perfectly clean. It did need partitioning but anyone buying this should know the basics. Used Parted magic to write gpt partition table, then partitioned for a Linux EFI install. All went well and have been using it for two weeks with no issues.
