0B32043 WD Ultrastar SSD800MH.B 800GB SAS 2.5" Server SSD

High-Performance 2.5" SAS Enterprise SSD for Write-Intensive Tier-1 Storage with the 0B32043

The 0B32043 is a WD Ultrastar / HGST SSD800MH.B 800GB enterprise SAS SSD designed for 24x7 hot-swap server bays where consistent write latency and sustained durability are operational priorities. As a dual-port SAS device, the 0B32043 aligns with redundant controller architectures and high-availability backplanes, supporting predictable service behavior during path failover events.

Built on an MLC NAND architecture, the 0B32043 targets write-intensive tiers such as database logging/journaling, metadata, and cache layers that benefit from high 4K IOPS and stable performance under mixed queues. With up to 1100 MB/s read and 765 MB/s write throughput, the 0B32043 integrates cleanly into SAS storage stacks without requiring PCIe slot consumption, preserving expansion lanes for network, accelerator, or HBA growth. Security is addressed through SED capability with TCG Enterprise SSC compliance, enabling drive-level encryption integration into enterprise key management policies.

Why Choose the 0B32043?

The 0B32043 delivers a balanced density-to-endurance profile for Tier-1 write-heavy volumes, pairing 25 DWPD and 36.5 PBW durability with hot-swap serviceability to reduce operational risk in clustered storage and virtualisation datastores. For infrastructure teams standardising on SAS, the 0B32043 supports scalable deployment across chassis and shelves while maintaining enterprise reliability characteristics suited to continuous duty cycles.

WD engineers the Ultrastar portfolio for data centre predictability, focusing on consistent performance envelopes, rigorous qualification, and long-life validation aligned with common server and storage platform standards. With a 2.0M hours MTBF target and efficient power behavior, the 0B32043 is designed for controlled thermals and stable operation in dense rack environments.

Key Applications:

• Database logging and journaling
• Write-intensive Tier-1 storage
• Virtualisation datastores
• Cache and metadata acceleration
• 24x7 server storage deployments
