About WD WD20EFRX

The WD WD20EFRX Red 2TB NAS hard drive is designed and tested for compatibility in the unique 24x7 operating environment and demanding system requirements of home and small office Network Attached Storage (NAS). Built in NASware optimizes power use resulting in significant power savings and lower hard drive operating temperatures. This improves the overall reliability and performance of the drive and reduces the NAS of ownership.

WD WD20EFRX Features

  • Compatibility: Desktop hard drive is not always tested for compatibility in NAS and can present problems during integration
  • Reliability: Most desktop drive is not designed for the high operating temperatures or for 24x7 operating environments making them less reliable when used in a NAS system
  • Error recovery controls: Desktop drive is not traditionally designed for RAID environments and have controls that prevent the RAID controller from assisting in the event of an error which can cause the hard drive to drop off the RAID after a period of time
  • Noise and vibration: Typically designed for single drive applications, average desktop drive is not optimized for multi-drive systems which have higher noise and vibration levels. When these drives are added to a NAS, the additional vibration can reduce the reliability and life span of the drive
  • Enhanced reliability: Your NAS systems is always on, a highly reliable drive is essential. With a 35% MTBF improvement over standard desktop drives, this WD WD20EFRX Red drive is designed and manufactured to be a more reliable and robust solution
  • Energy efficient: Reduce your electricity bill and carbon footprint with the WD WD20EFRX Red drive. Innovative technology reduces power consumption and lowers the operating temperature, resulting in a more reliable and affordable solution for always on 24x7 NAS environments

The right tool for the right job.

By

This is the perfect product for heavy data users that can't afford enterprise grade HDDs, such as the WD RE4. It has a range of features that make it better suited than any other consumer HDD for RAID arrays or ZFS pools, especially for multi-user network environments. I'm replacing several aging WD Greens with these WD Reds.

Product good but Adorama service bad

By

Well, the hard disks were excellent. very quiet... But what I can say about Adorama shipping quality. I bought 2 hard disks which were wrapped in a thin non static plastic and thrown in a box along with 1 piece of void fill air pouch. The hardisks were free to move inside the box.The hard disks are working as of now but I have no idea how this has damaged the magnetic disks and heads affecting the life of product.
