WD Red^™ Plus - 2TB

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.
