0B32284 WD Ultrastar SSD1600MR 1TB SAS 2.5" Server SSD

High-Performance 2.5-inch Enterprise SAS SSD for mixed-workload tiering with the 0B32284

The 0B32284 is a 1.0TB 2.5-inch hot-swap SAS SSD engineered for servers with SAS backplanes where low-latency datastore acceleration and predictable QoS matter. Built on MLC NAND and tuned for mixed workloads, it supports read caching and tiering layers that reduce pressure on primary storage while keeping virtualised clusters responsive during consolidation and peak IO windows.

With SAS connectivity optimised for enterprise controllers and expander topologies, the 0B32284 sustains high throughput and consistent 4K performance for metadata-heavy operations, log streams, and VM boot storms. Its endurance profile at 2.63 DWPD and 4800 TBW aligns with sustained write workloads, while 24x7 duty rating and a 2.0M-hour MTBF support dense deployments where swap cycles and continuous operation are expected. For data-at-rest protection in regulated environments, the 0B32284 integrates a self-encrypting architecture with 256-bit AES and TCG Enterprise management, enabling policy-based key control without sacrificing hot-swap serviceability.

Why Choose the 0B32284?

The 0B32284 delivers an efficient density-to-performance ratio for SAS-based server fleets, enabling straightforward drop-in upgrades without changing controller standards or chassis wiring. It scales cleanly across hosts and nodes, supports predictable operation under mixed read/write pressure, and reduces operational risk through enterprise-grade reliability, endurance, and security controls suited to multi-tenant infrastructure.

WD designs Ultrastar-class storage with a focus on lifecycle consistency, validation against enterprise interoperability requirements, and operational stability in modern data centres. The platform is engineered for controlled latency, sustained write behaviour, and security features that align with standardised compliance and key-management practices.

Key Applications:

• Mixed-workload read caching and tiering
• Virtualisation datastore acceleration
• Database and transaction logs
• HCI and clustered storage nodes
• Power-loss-sensitive write environments
