Packed with power to handle the small- to medium-sized business NAS environments and increased workloads1 for SOHO customers, WD Red™ Plus is ideal for archiving and sharing, as well as RAID array rebuilding on systems using ZFS and other file systems. Built and tested for up to 8-bay NAS systems, these drives give you the flexibility, versatility, and confidence in storing and sharing your precious home and work files.

For Small or Medium Businesses 

Stream, backup, share, and organize your digital content with a NAS and WD Red™ Plus drives designed to effortlessly share content with the devices at your home or business. NASware™ 3.0 technology increases your drives’ compatibility with your existing network and devices. For larger businesses with up to 24 bays, count on WD Red™ Pro drives to deliver exceptional performance.

Exclusive NASware 3.0

Not just any drive will do. Get up to 112TB of capacity in your 8-bay NAS system and with Western Digital's exclusive NASware 3.0 technology, you can optimize each and every drive. Built into every WD Red™ Plus hard drive, NASware 3.0’s advanced technology improves storage performance by increasing compatibility, integration, upgradeability, and reliability.

Built for Optimum NAS Compatibility

WD Red™ Plus drives with NASware™ technology takes the guesswork out of selecting a drive. Optimized for NAS systems, our unique algorithm balances performance and reliability in NAS and RAID environments. Simply put, a WD Red™ Plus drive is one of the most compatible drives available for NAS enclosures. But don’t take our word for it. WD Red™ Plus drives are a reflection of extensive NAS partner technology engagement and compatibility-testing. 

WD Red™ Pro for Big Business

If you’re looking for heavy duty performance for NAS, WD Red™ Pro drives deliver exceptional performance for the medium to large business customer with extreme demands. For NAS environments with 9 to 24 bays, WD Red™ Pro drives deliver uncompromising performance and unwavering assurance backed by a 5-year limited warranty. 

3D Active Balance Plus

Our enhanced dual-plane balance control technology significantly improves the overall drive performance and reliability. Hard drives that are not properly balanced may cause excessive vibration and noise in a multi-drive system, reduce the hard drive life span, and degrade the performance over time.

24/7 Environment 

Since your NAS system is always on, a reliable drive is essential. With an MTBF of up to 1 million hours, the WD Red™ Plus drive is engineered to tackle 24x7 environments. 

Premium Support and a 3-year Limited Warranty

Confidently upgrade your NAS performance with the assurance of a 3-year limited warranty, coupled with world-class support services included with every WD Red™ Plus drive. 

Desktop Drives vs. WD Red™ Plus

Do right by your NAS and choose the drive purpose-built for NAS with an array of features to help preserve your data and maintain optimum performance. Take the following into consideration when choosing a hard drive for your NAS:  

  • Compatibility: Unlike desktop drives, these drives are specifically tested for compatibility with NAS systems for optimum performance.  
  • Reliability: The always-on environment of a NAS or RAID is a hot one, and desktop drives aren’t typically designed and tested under those conditions like WD Red™ Plus drives are. 
  • Error Recovery Controls:  WD Red™ Plus NAS hard drives are specifically designed with RAID error recovery control to help reduce failures within the NAS system. 
  • Noise and Vibration Protection: Designed to operate solo, desktop drives typically offer little or no protection from the noise and vibration present in a multi-drive system. WD Red™ Plus drives are designed to thrive in multi-bay NAS system environments. 

1 Workload Rate is defined as the amount of user data transferred to or from the hard drive. Workload Rate is annualized (TB transferred ? (8760 / recorded power-on hours)). Workload Rate will vary depending on your hardware and software components and configurations.

Q: how does this differ performance wise to the green?
Answer by Website User on 11th March 2015
Generally speaking, Greens are eco-friendly oriented with less power consumption, whereas Reds are performance oriented drives that spin at variable rates and are suited to 24/7 operation in a RAID array. Therefore the Reds have a higher performance rate than the Greens. -Jake

Q: On the spec this says, 3D Active Balance Plus....does this mean if I have a 3d film on my drive I can watch it in 3D
Answer by CCL on 12th October 2013
Western Digital that 3D Active Balance Plus technology equates to the fact that "Our enhanced dual-plane balance control technology significantly improves the overall drive performance and reliability. Hard drives that are not properly balanced may cause excessive vibration and noise in a multi-drive system, reduce the hard drive life span, and degrade the performance over time." -* RH

Excellent next day delivery - less than 24 hours from order

Just plugged it in and started using it. Seems to be quiet, and plenty fast for my needs. I haven't tested the extra movement protection thingy, but it's a nice to have.


2 months ago

good deal, great drive for my Nas


10 months ago

I purchased this as an additional drive to be added to an existing RAID group. The drive sits beside other WD Red drives with an earlier version of NASware and they get on with the job they're there to do.

Plug into the storage network and forget them. Great drives that go on and on.

This is the third Western Digital Red 4TB HDD I have purchased and so far, the first 2 being proved to be very reliable and have not had any issues or faulty sectors over 4 years in a NAS drive. Of my many Western Digital HDD's bought over many years; I have had one failure which was speedily replaced under warranty.


August 2019

What can you say, it's a disk drive, but classic WD quality, they just work and keep on working


December 2018

This disk with its godlike mechanically spinning platter was easily installed into my NAS' raid and the RAID rebuilt successfully, I can now sleep peacefully knowing my state of the art RAID5 is back to it's top notch self. 10/10 will see you again soon WD

This is a great product. I previously bought 2 of these drives from Amazon which failed within 3 months. Both drives came from Amazon loose in a large box with no protection. I bought the same from CCL computers and it came packed in proper hard drive padded protection case. We are now well past the three month mark and its working fine. It is clear CCL Computers treats these drives with the care they deserve.
