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 environments of NAS and RAID can reach intense temperatures. WD Red Plus drives are designed and tested to perform under those extreme conditions.
  • 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.

Tackle Intensity with WD Red Plus

Packed with power to handle NAS environments in home offices up to medium-sized businesses, WD Red Plus is ideal for helping protect, archive, and share valuable data in NAS systems with up to 8 bays. WD Red Plus NAS drives give you the flexibility, versatility and confidence you need for your important home and work files.

For Small or Medium Businesses

WD Red Plus drives deliver the speed and capacity business customers require to store, protect, and share increasing amounts of data with a growing number of NAS users. For NAS systems with up to 8 bays, WD Red Plus drives deliver uncompromising performance and unwavering assurance backed by a 3-year limited warranty.

For Home Office and Power Users

Whether you’re a power user looking to store high-resolution videos or running a home office with thousands of electronic documents, WD Red Plus drives are designed to help you effortlessly organize, protect and share your digital content.

Exclusive NASware™ Technology

Built into every WD Red Plus hard drive is Western Digital’s exclusive NASware 3.0 technology. NASware is advanced technology that improves your NAS system by increasing compatibility, integration, upgradeability, and reliability. WD Red Plus drives with NASware technology take the guesswork out of selecting a drive for your NAS system.

Built for Optimum NAS Compatibility

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.

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 hours9, the WD Red Plus drive is engineered to tackle 24/7 environments.

Premium Support and a 3-year Limited Warranty
