About the Product
Ultrastar 7K6000 also delivers greater storage efficiency through high performance, achieving up to 3X higher random write performance, thanks to HGST media cache architecture, a diskbased caching technology, which provides a large non-volatile cache on the disk.
The new Ultrastar 7K4000 provides twice the data storage capacity of the prior generation Ultrastar 7K3000 drive, and does so using fewer watts. Hitachi BDE implementation encrypts all data.

  • HDD for enterprise applications. I used in RAID 5 NAS.

Hitachi Ultrastar 7K6000 6TB 7200 RPM SATA 3.5" Hard Drive
  • I split the power between two Sata power cables and everything is fine. Works like a charm.
  • I’m using it in a home Win10 PC in a non-RAID configuration. Sound is ok.
  • No bad blocks, no SMART errors, packaging was excellent. Lifetime power on time was a bit high.
  • They work perfectly in my new FreeNAS server. Quiet running, and fast response times.
  • This is a great product. Packaged well. Easy installation and setup.
Hitachi Ultrastar 7K4000 4TB 64MB Cache 7200RPM Internal Enterprise Hard Drive
  • Two of this HDD's running in my QNAP NAS with no errors.
  • This set I run in my NAS powered by Unraid. They work, no errors.
  • Installed in my snapraid/mergerfs server and going well so far.
  • I did not like this HDD. Very noisy and slow operating.
