Western Digital Red 3TB NAS HDD (WD30EFRX): SATA 6Gb/s, 64MB cache, 5400 RPM class, and native CMR recording with NASware 3.0 for reliable 24/7 multi-bay RAID arrays.

Product Details

Overview

The Western Digital Red 3TB (WD30EFRX) is purpose-engineered from the ground up for connected home, SOHO, and small business network attached storage (NAS) environments operating up to 8 bays. Built utilizing proven Conventional Magnetic Recording (CMR) technology, the drive fundamentally avoids the RAID rebuild penalties and write-cliff slowdowns associated with SMR alternatives, ensuring deterministic and dependable performance across continuous 24/7 multi-user write cycles.

At the heart of the drive is Western Digital's exclusive NASware 3.0 advanced firmware technology. NASware 3.0 fine-tunes drive parameters to match NAS system workloads, addressing compatibility, integration, upgradeability, reliability, and total cost of ownership that standard desktop hard drives are not designed to handle.

Architecture & Performance

Operating on the SATA 6 Gb/s interface, the WD30EFRX features a 5,400 RPM class spindle speed paired with a 64MB multi-segmented DRAM cache buffer. This balance of rotational velocity and data caching delivers sustained internal data transfer rates of up to 147 MB/s, while maintaining exceptionally low thermal output and acoustic profiles.

To combat RAID degradation, NASware 3.0 integrates intelligent Time-Limited Error Recovery (TLER), preventing the drive from being prematurely dropped from a storage array during extended bad-sector recovery cycles. Additionally, the drive incorporates 3D Active Balance Plus—an advanced dual-plane balance control technology that drastically reduces rotational vibration and chassis resonance in dense multi-drive enclosures. Rated for a 1,000,000-hour Mean Time Between Failures (MTBF) and an annual workload rating of up to 180 TB/year, the WD30EFRX provides enterprise-grade reliability in an energy-efficient consumer NAS form factor.
