Tuned for NAS with NASware

Western Digital’s exclusive NASware technology fine tunes drive parameters to match NAS system workloads which helps increase performance and reliability.

Designed for Continuous Operation

Since your NAS system is always on, a reliable drive is essential. The WD40EFZZ is designed for systems that operate 24x7, giving users the confidence of knowing they can reliably access their data.

Tested for Dependable Compatibility

Western Digital partners with a wide range of NAS system vendors for extensive testing to ensure compatibility with most NAS enclosures.

Optimised for Lower TCO

The WD40EFZZ is engineered to use less power (versus previous models) and run cooler, which reduces operating costs and helps reduce heat in thermally challenged NAS boxes.

Powered for Strong Performance

Despite using less power, the WD40EFZZ has plenty of bandwidth to handle the mixed performance demands of multi-drive NAS systems.

Balanced for Increased Reliability

Hard drives that are not properly balanced may cause excessive vibration and noise in multi-drive systems, which could reduce hard drive life span and degrade the performance over time. WD's enhanced dual-plane balance control technology significantly improves balance and increases overall drive performance and reliability.

Desktop Drives vs. WD Red Plus

It is important to choose a drive purpose-built for RAID-optimised NAS systems to ensure optimum performance and preserve your valuable data. Take the following into consideration when choosing a hard drive for your NAS:

• Compatibility
  Unlike desktop drives, this drive is specifically designed and tested for NAS and include NASware technology which fine tunes drive parameters to match NAS system workloads for optimum performance.

• Reliability
  Desktop drives aren’t typically designed for the demands of an always-on NAS environment. The WD40EFZZ Red Plus hard drive is designed to perform under tough conditions encountered in high-intensity 24x7 multi-user NAS environments.

• RAID Ready:
  This WD Red Plus NAS hard drive is engineered with RAID error recovery control to help reduce failures within multi-bay NAS systems, unlike most desktop drives that are configured for generic use.

• 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. This WD Red Plus drive includes Rotation Vibration (RV) sensors that anticipate and proactively counteract disturbances caused by increased vibration often found in multi-bay NAS systems.
