WD Red Pro NAS Storage NAS Hard Drive
The next generation of hard drives for medium to large business network attached storage systems.
Storage for 8 to 16 bay NAS solutions
Joining the original color of NAS, WD Red Pro continues the formula of success that has led the WD Red product family by adding support beyond consumer, SOHO, and small business markets into medium and large 8-16 bay business storage systems. WD Red Pro hard drives integrate WD's exclusive technology, NASware 3.0, to provide unparalleled support for drive compatibility, reliability, and performance.
Designed specifically with SMB customers in mind the WD Red family has expanded with the addition of WD Red Pro, which is available for the 8 to 16 bay medium to large-scale NAS environments. With capacities up to 4 TB, WD Red Pro carries a 5-year limited warranty and was engineered to handle the increased workloads from your business.
Exclusive NASware 3.0 technology
Our exclusive advanced firmware technology built into every WD Red Pro drive, NASware 3.0 enables seamless integration, robust data protection and optimal performance for systems operating in the demanding NAS environment.
Experienced in NAS
WD Red is a reflection of the most extensive NAS partner compatibility- testing list that is available on the market.* That means when you buy a NAS enclosure, you can trust that WD Red will be the most compatible drive available. Our pride is in our product and our vision is shared with our customers.
*Data reflects products in production as of April 2014.
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.
The right choice
WD Red Pro is designed specifically for medium to large business NAS systems and PCs with RAID.
Enhanced Accuracy for NAS
For overall enhanced accuracy for NAS, WD Red Pro is also equipped with dual actuator technology which improves positional accuracy over the data tracks and head positioning. StableTrac technology then secures the motor shaft at both ends to reduce system-induced vibration and stabilize the drive platters for accurate tracking during read and write operations. Both technologies are important for larger 8 to 16 bay NAS environments.
Upgrading your drive is easy
WD Acronis TrueImage, available as a free download on the WD Support site, enables you to copy all your data to a new drive so you don't have to reinstall your operating system to get all the benefits of a new drive.
All WD drives purchased from Amazon.com are shipped in WD-certified hard drive packaging. It is designed and fully tested to provide WD products with the highest of safety while in transit. With WD-certified packaging, you can rest assured that your WD hard drive will arrive safely, fully protected, in a non-descript, easy-open package.
WD Red Pro NAS hard drives are recommended for use in medium to large 8-16 bay NAS systems. For systems that use less than 8 bay NAS solutions, please consider WD Red hard drives.***
***WD hard drives are designed and tested for use in specific applications and environments. This ensures that your hard drive is compatible with and functions properly in your application. Our hard drives are warranted against defects in materials and workmanship in the system for which they were designed. Use in systems other than for what the hard drive was designed could result in compatibility problems that affect proper function, unrelated to material and/or workmanship defects.
Features at a glance

Since your NAS system is always on, a highly reliable drive is essential. With a 35% MTBF improvement over standard drives, the WD Red drive with NASware 3.0 is designed for the 24x7 environment.
Extended Drive Testing
The 8 to 16 bay NAS environment is very demanding on a hard drive with added vibration, heat and other factors. This is why every WD Red Pro drive is shipped with extended thermal cycle burn-in testing which ensure each drive for extended reliable operation.
Error Recovery Prevention
Built specifically for RAID and NAS environments, WD Red Pro drives come equipped with time-limited error recovery (TLER) as part of NASware 3.0, which prevents drive fallout and is caused by the extended hard drive error-recovery processes common to desktop drives.
