WD Red Plus 4TB Internal NAS HDD – 3.5" SATA
The WD Red Plus 4TB Internal NAS HDD is designed for power users and small to medium business NAS environments. Optimized for RAID-ready, multi-bay NAS systems, it delivers the speed and capacity needed to store, protect, and share growing volumes of data with increased power efficiency.
Designed for NAS Performance and Reliability
- Purpose-built for small to medium NAS environments
- Handles demanding workloads for power users and businesses
- Delivers the speed and capacity required for mid-sized, RAID-optimized NAS systems
NASware Technology for Tuned Performance
WD Red Plus drives feature Western Digital’s exclusive NASware technology, which fine tunes drive parameters to match NAS system workloads. This helps:
- Increase performance in NAS applications
- Enhance reliability in multi-drive environments
Built for 24x7 Operation
Because NAS systems are typically always on, reliability is essential. WD Red Plus hard drives are designed for systems that operate 24x7, giving users confidence in dependable data access at any time.
Tested for Broad NAS Compatibility
Western Digital works with a wide range of NAS system vendors to conduct extensive compatibility testing. This helps ensure WD Red Plus drives work dependably with most NAS enclosures.
Optimized for Lower TCO
WD Red Plus drives are engineered to use less power (versus previous models) and run cooler, helping to:
- Reduce overall operating costs
- Lower heat generation in thermally challenged NAS enclosures
Strong Performance with Power Efficiency
Despite reduced power consumption, WD Red Plus drives provide ample bandwidth to support the mixed performance demands of multi-drive NAS systems.
Balanced for Increased Reliability
Improperly balanced drives can cause excess vibration and noise in multi-drive systems, which may reduce drive lifespan and degrade performance over time. WD’s enhanced dual-plane balance control technology helps:
- Significantly improve drive balance
- Increase overall performance and reliability
Backed by Support and Warranty
As an industry-leading hard drive manufacturer, Western Digital supports WD Red Plus NAS storage solutions with:
- A 3-year limited warranty
- World-class support services for hassle-free data storage
Why Choose WD Red Plus Over Desktop Drives
When selecting a hard drive for your RAID-optimized NAS system, it is important to choose one purpose-built for NAS. Consider the following:
Compatibility
- WD Red Plus hard drives are specifically designed and tested for NAS.
- NASware technology fine tunes drive parameters to match NAS workloads for optimum performance.
Reliability
- Desktop drives are not typically designed for always-on NAS environments.
- WD Red Plus drives are built to perform under tough conditions in high-intensity, 24x7, multi-user NAS environments.
RAID Ready
- WD Red hard drives are engineered with RAID error recovery control to help reduce failures in multi-bay NAS systems.
- Most desktop drives are configured for generic use, not RAID-optimized NAS.
Noise and Vibration Protection
- Desktop drives, designed to operate solo, usually offer minimal noise and vibration protection in multi-drive systems.
- WD Red hard drives include Rotation Vibration (RV) sensors that anticipate and proactively counteract disturbances from increased vibration often found in multi-bay NAS enclosures.
