WD100EFAX WD Red Plus 10TB 256 MB Server HDD

High-Capacity 3.5-inch NAS HDD featuring CMR reliability and 24/7 duty cycle with the WD100EFAX

The WD100EFAX is a 10TB WD Red Plus internal HDD engineered for small and medium business NAS platforms and RAID arrays where sustained sequential throughput and predictable rebuild behavior matter. As a CMR drive, WD100EFAX maintains consistent write performance under multi-bay contention, supporting file services and shared storage pools that run continuously.

In modern NAS architectures, controller CPUs and network interfaces accelerate ingest and client concurrency, but array stability depends on storage media behavior. WD100EFAX complements these platforms with 512e formatting for broad RAID compatibility and a 256MB cache tuned for mixed read/write patterns. Its helium-filled design targets higher areal density with controlled vibration characteristics in populated enclosures, aligning with expansion via additional bays rather than PCIe-attached flash, and providing a cost-efficient nearline tier for backups and archive repositories.

Why Choose the WD100EFAX?

WD100EFAX fits deployments that prioritize capacity density per U and operational continuity over peak IOPS, making it a pragmatic building block for RAID-protected NAS volumes. WD100EFAX supports scalable growth by standardizing on a CMR profile that reduces risk during parity operations, while its 1,000,000 hours MTBF rating and low power envelope help maintain predictable service levels in always-on environments.

WD designs the Red Plus family around NAS duty cycles, emphasizing validated firmware behavior, interoperability across common NAS controllers, and mechanical engineering that supports multi-drive chassis. This approach aligns with data centre expectations for consistent performance, manageable thermals, and long service life under 24/7 operation.

Key Applications:

• SMB NAS file services
• RAID arrays and rebuild-sensitive volumes
• Backup targets and retention repositories
• Nearline archive storage
• Media libraries and shared content stores
