HUC109045CSS601 WD Ultrastar C10K900 0.45TB SAS 64 MB 2.5" Server HDD

Enterprise 2.5in SAS 10K HDD for secure primary storage with the HUC109045CSS601

The HUC109045CSS601 is a WD Ultrastar C10K900 2.5in enterprise HDD engineered for legacy and mixed-generation server platforms that standardise on SAS backplanes. Designed for consistent low-latency IO, it provides 10,000 RPM performance with CMR recording and a 64MB cache, supporting predictable behaviour under sustained transactional pressure in always-on environments.

With a 12Gb/s SAS single-port interface, the HUC109045CSS601 aligns to enterprise RAID controllers and expander architectures where deterministic queueing and error recovery policies matter more than peak burst rates. Capacity is optimised for boot/OS, logging, and hot data tiers, while the 2.5in form factor supports higher spindle density per chassis and straightforward serviceability in front-access drive bays. For compliance-driven deployments, the HUC109045CSS601 integrates Self-Encrypting Drive capabilities with TCG Enterprise support, enabling hardware-based encryption enforcement without shifting CPU cycles away from application workloads.

Why Choose the HUC109045CSS601?

The HUC109045CSS601 delivers a balanced density-to-performance profile for SAS infrastructures that still rely on rotating media for predictable steady-state throughput and controlled operational cost. It is well suited for scale-out drive populations, where consistent firmware behaviour, 24x7 duty-cycle readiness, and encryption policy alignment reduce deployment friction across server and array fleets.

WD Ultrastar engineering focuses on datacentre reliability, validated interoperability with enterprise controllers, and operational consistency across large drive counts. The platform is designed to integrate cleanly with modern monitoring and lifecycle processes, supporting disciplined change control in production environments.

Key Applications:

• Boot and OS volumes on SAS backplanes
• Database logs and journal tiers
• Primary storage for legacy servers and arrays
• Encrypted data-at-rest compliance deployments
