0F22795 WD Ultrastar 7K6000 4TB SAS 128 MB 3.5" Server HDD

High-Performance 3.5in Enterprise SAS HDD for Tier-2 Disk Pools and RAID with the 0F22795

The 0F22795 is a WD/HGST Ultrastar 7K6000 4TB 3.5in internal HDD engineered for 24x7 duty cycles in server and storage-array architectures where predictable throughput and operational consistency matter more than ultra-low latency. With a 7200 RPM mechanical platform and CMR recording, the 0F22795 supports steady sustained write behavior, making it suitable for RAID groups and bulk capacity nodes that must maintain rebuild stability and long-term data integrity.

Architecturally, the 0F22795 integrates through a single-port SAS interface to align with enterprise backplanes and expander topologies, enabling controlled queueing, robust error handling, and streamlined integration into shared storage shelves. Support for 4Kn with 512e emulation provides deployment flexibility across modern and transitional operating environments, while the 128MB cache helps optimize command coalescing and sequential transfer efficiency for backup-to-disk, log, and archive repositories. The 0F22795 also includes Instant Secure Erase (ISE) to simplify decommissioning workflows and reduce operational friction in lifecycle management.

Why Choose the 0F22795?

The 0F22795 delivers a practical density-to-performance balance for scale-out capacity, allowing IT teams to expand Tier-2 pools without shifting to higher-cost media tiers. With an MTBF rating of 2.0M hours and continuous operation design targets, the 0F22795 supports predictable fleet behavior, consistent RAID operation, and straightforward capacity scaling across server nodes and storage enclosures.

WD’s Ultrastar engineering focuses on datacenter reliability, sustained duty-cycle operation, and interface compatibility aligned with enterprise SAS standards, supporting repeatable deployments in heterogeneous rack and array environments.
