On this page you'll find a ranking of the best WD products in this category. To give you a quick overview, we've already ranked the most important information about the products for you.
1. WD Red Plus
High-performance hard drives designed for performance, reliability, and energy efficiency in small to medium NAS environments. WD Red Plus drives are ideal for power user workloads and NAS environments in small to medium-sized businesses. They provide the necessary speed and capacity to efficiently store, protect, and share growing amounts of data in mid-sized RAID-optimized NAS systems.
The exclusive Western Digital NASware technology optimizes drive parameters for NAS system workloads to enhance performance and reliability.
Your NAS system runs around the clock. Therefore, highly reliable storage is essential. WD Red Plus drives are designed for continuous operation, giving users the assurance that they can reliably access their data.
Western Digital collaborates with various NAS system manufacturers to conduct extensive testing and ensure compatibility with most NAS enclosures.
WD Red Plus drives consume less power than previous models and run cooler, reducing operating costs and minimizing heat in hard-to-cool NAS enclosures.
Although they consume less power, the drives have a significant bandwidth to meet the mixed performance demands of multi-drive NAS systems.
Drives without proper mass balancing can cause excessive vibrations and noise in multi-drive systems, which can shorten the lifespan of the drives and lead to performance degradation over time.

2. WD Red Pro
WD Red Pro hard drives are designed for high-intensity workloads in commercial and enterprise NAS environments with continuous operation and multiple users. WD Red Pro drives deliver the performance, scalability, and reliability that businesses need to store, share, and collaborate on large amounts of data in RAID-optimized, multi-bay NAS systems.

3. WD Purple
WD Purple drives are designed to meet the challenges of 24/7 video surveillance. These drives are specifically engineered for monitoring and can withstand significant temperature fluctuations and device vibrations in NVR environments. An average desktop drive is only built for short intervals, not for the harsh 24/7 operational environment of a high-resolution surveillance system. With WD Purple drives, you get reliable surveillance-class storage that has been tested for compatibility with a variety of security systems. The exclusive AllFrame technology helps reduce frame loss and improve overall video playback.

4. WD Blue
The higher standard in storage
