0T00167 WD s846 2TB SAS 2.5" Server SSD

Enterprise 2.5" Hot-Swap SAS SSD for Read-Intensive Tiers and Secure Boot with the 0T00167

The 0T00167 is a 2TB 2.5" SAS SSD engineered for server boot volumes and read-intensive data tiers where predictable latency and serviceability matter. As a hot-swap internal drive, the 0T00167 aligns with enterprise backplanes and RAID/HBA architectures, enabling online replacement and streamlined maintenance windows without disrupting operational continuity.

Built on MLC NAND, the 0T00167 targets consistent performance under mixed I/O patterns, delivering up to 520 MB/s sequential read and 65K 4K random read IOPS for metadata-heavy access. The SAS interface provides robust command queuing and multi-initiator-capable storage topologies, supporting dense virtualisation clusters and log or cache tiers. With endurance rated at 2.767 DWPD over 5 years (10,100 TBW), the 0T00167 is suited for sustained write activity in journaling, logging, and acceleration roles while maintaining lifecycle control in standardised fleet deployments.

Why Choose the 0T00167?

The 0T00167 delivers a practical density-to-performance balance for enterprise platforms that require SAS-managed reliability, hot-swap operations, and controlled endurance for 24x7 duty cycles. The 0T00167 simplifies scaling by fitting into existing 2.5" bays and SAS storage domains, supporting consistent provisioning across nodes and reducing variance in boot, cache, and tiering configurations.

WD designs this drive family around data centre requirements for predictable behavior, long service life, and integration with standard server storage stacks. The architecture is validated for continuous operation and aligns with modern operational practices for secure, serviceable, high-availability infrastructure.

Key Applications:

• Server boot and OS volumes
• Read-intensive data tiers
• Virtualisation cache and metadata acceleration
• Database log and journal storage
• Edge and branch 24x7 internal storage
