WD30EFAX WD Red 3TB SATA 256 MB 3.5" NAS HDD

Enterprise NAS 3.5in SATA HDD for efficient capacity tiers with the WD30EFAX

The WD30EFAX is a 3.5in internal SATA hard drive engineered for small NAS arrays where predictable, sequential access is the dominant pattern. In environments that prioritize dependable capacity over peak IOPS, the WD30EFAX supports steady file services and archive tiers without requiring a CPU or GPU platform dependency, making it a straightforward fit for appliance-based NAS and entry rack storage nodes.

Built on Advanced Format media with 4Kn and 512e emulation, the WD30EFAX integrates cleanly with common controller firmware expectations and OS storage stacks. SMR recording technology and a 5400 RPM design emphasize density and power efficiency, while a 256MB cache and Native Command Queuing help maintain smooth command handling under multi-user access. For expansion planning, SATA connectivity enables broad compatibility across HBA and chipset ports, supporting incremental scale-out without consuming PCIe lanes reserved for high-speed networking or NVMe tiers.

Why Choose the WD30EFAX?

The WD30EFAX is positioned for cost-controlled NAS capacity where reliability, acoustics, and 24x7 duty cycle matter more than sustained random-write performance. With NAS-oriented firmware behavior and ERC, the WD30EFAX aligns to RAID environments that favor stable error recovery and predictable rebuild behavior, while its SMR profile is best deployed for low-change datasets, backups, and sequential-heavy storage pools.

WD designs Red NAS drives to balance compatibility, power draw, and service continuity in always-on enclosures. The platform focus on NASware tuning, controlled error handling, and long-life components helps maintain consistent operation across mixed SMB/SOHO workloads and modern data centre rack-edge deployments.

Key Applications:

• Small NAS arrays and SOHO file services
• Archive and tiered capacity storage
• Sequential backup repositories
• Media libraries and content staging
• Light virtualization datastores with low churn
