COMBO DEALS: Buy Together and SAVE!
Tackle Intensity with WD Red™ Plus
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.
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.

Brought This To Expand The Storage Of My Media Server PC
WD-Red never disappoints
have been using these on my QNAP NAS for the last 8 years, no fail but SMARTS detected potential error, so instead of waiting for a data loss I bought one more WD another, hope I can get another 8 years out of it.
Perfect price / performance for NAS
It's not the fastest but great price for the capacity - it's a DMSMR drive so it's the best choice for sequential performance for the price.
Unknown yet - Have had problems, still sorting it out
- The original purchase went okay, prompt delivery.
- The 8Tb disk failed when put into a Nastor device.
- A techie friend said it might have to be specially formatted because it was a large, 8Tb storage,
- I bought a cable and tried it in another PC, still failed. Just not seen by the PC, nor by the Nastor.
- So I conferred with a local PC shop, ModernPC, where there is a very smart techie friend. But he said it was defective, I should return it.
- There was quite a rigmarole reporting it for a replacement, but eventually that arrived.
- It also failed in the Nastor, so I will take it again, inside the Nastor, to see if we can get it...view more
Useful and fair priced
Bought 2 of these harddrives to start Off my own Home server. As a filmmaker, I needed some security, regarding the backing Up of my Files. I implemented them into an Unraid Environment, which works very well.
Delivery took about a week, Installing-process took me about 30 Minutes.
I know this probably isnt the cheapest Option (barracuda seems cheaper), but after Reading a bunch of Reviews and having Spoken to people With some experience With Servers, the REDs seem like a very solid option.
solid as always
solid as always
Always a safe choice
I bought two to replace my 20 year old disk. It was with some bad sectors so I will go with this new ones for other 20 years.
Didn't last even 12 hours
Failed before it had even 1TB written to it. USB enclosure may have been under rated or buggy/worn out, but Seagate Ironwolf Pro I got to replace it for an extra 20 bucks survived the same bad enclosure and has been rock solid in a new enclosure and I have high hope for that to last 2-4 years like usual for spinning rust.
