0F30141 WD Ultrastar 12TB SATA 256 MB 3.5" Server HDD

High-Density 3.5in Enterprise SATA HDD featuring 4Kn CMR nearline architecture with the 0F30141

The 0F30141 is a 12TB 3.5in internal enterprise hard drive designed for capacity-centric server and storage array tiers where predictable throughput and continuous duty cycles matter more than low-latency flash. It aligns with modern x86 storage backplanes via a single-port SATA interface, enabling straightforward integration into scale-out nodes, backup targets, and general-purpose datacenter pools.

Architecturally, the 0F30141 combines 7200 RPM performance with CMR recording to maintain consistent write behavior under sustained ingestion and rebuild operations. Native 4Kn sector formatting supports efficient alignment for contemporary filesystems and object storage stacks, reducing write amplification risks compared with legacy emulation modes. A 256MB cache helps smooth burst workloads, while the helium-filled mechanical design is engineered for 24x7 operation with reduced turbulence and controlled power characteristics for dense enclosures.

Why Choose the 0F30141?

The 0F30141 delivers a balanced density-to-performance profile for enterprises expanding nearline capacity without changing chassis or controller architectures. With a 2.5 million hour MTBF and datacenter duty-cycle design, the 0F30141 supports predictable scaling across multiple drive groups, simplifying standardization for growth, replacement planning, and large-volume deployments in rack and storage-array environments.

WD designs Ultrastar-class drives around platform reliability, controlled acoustics and vibration tolerance, and consistent firmware behavior under storage workloads. The 0F30141 reflects WD’s focus on datacenter interoperability, supporting secure lifecycle processes such as Instant Secure Erase (ISE) and alignment with modern operational standards for continuous service.

Key Applications:

• Enterprise storage capacity expansion
• Backup and archive tiers
• Nearline storage pools
• General-purpose 24x7 HDD deployments
