Product details
High-performance hard drives designed for performance, reliability, and energy efficiency in small to medium NAS environments.
WD Red Plus hard drives are ideal for power user workloads and NAS environments of small to medium-sized businesses. They deliver the necessary speed and capacity to efficiently store, protect, and share growing amounts of data in mid-sized RAID-optimized NAS systems.
Optimized for NAS with NASware
The exclusive Western Digital NASware technology optimizes the hard drive parameters for NAS system workloads to enhance performance and reliability.
Designed for continuous operation
Your NAS system runs around the clock. Therefore, highly reliable storage is essential. WD Red Plus hard drives are designed for continuous operation, giving users the confidence that they can reliably access their data.
Tested for reliable compatibility
Western Digital collaborates with many different NAS system manufacturers to conduct extensive testing and ensure compatibility with most NAS enclosures.
Optimized for lower total cost of ownership
WD Red Plus hard drives consume less power than previous models and run cooler, reducing operating costs and minimizing heat in hard-to-cool NAS enclosures.
Lower power consumption, strong performance
Despite consuming less power, the hard drives have a significant bandwidth to meet the mixed performance demands of multi-drive NAS systems.
Balanced for increased reliability
Hard drives without proper mass balancing can cause excessive vibrations and noise in multi-drive systems, reducing the lifespan of the drives and leading to performance degradation over time.
