0TS1875 WD Ultrastar DC SN840 1.92TB U.2 NVMe 2.5" Server SSD

High-Performance U.2 NVMe Datacenter SSD for Hot-Swap Server Storage with the 0TS1875

The 0TS1875 is a WD Ultrastar DC SN840 1.92TB 2.5in U.2 NVMe SSD engineered for enterprise server boot, cache, and mixed read-intensive tiers where consistent latency matters more than peak burst. Built on TLC NAND with power-loss protection, the 0TS1875 supports 24/7 duty cycles and predictable behavior under virtualization metadata and OS-heavy footprints.

By using the NVMe protocol over PCIe connectivity via the U.2 interface, the 0TS1875 integrates cleanly into modern rack server backplanes and storage nodes designed for hot-swap serviceability. Sequential throughput up to 3311 MB/s read and 2181 MB/s write, combined with strong 4K random read performance, enables fast VM boot storms, responsive hypervisors, and efficient metadata caching while maintaining controlled write amplification at 1 DWPD endurance.

Why Choose the 0TS1875?

The 0TS1875 delivers an enterprise density-to-performance profile suited for scaling boot and cache media across clusters without overprovisioning higher-endurance drives. With hot-swap U.2 deployment, the 0TS1875 supports streamlined maintenance windows and inventory standardization, while features such as Secure Erase and power-loss protection reinforce operational reliability in multi-tenant and always-on environments.

WD designs the Ultrastar datacenter portfolio around sustained workload integrity, qualification for server platforms, and alignment with contemporary data center requirements for predictable endurance, thermal behavior, and fleet manageability. The 0TS1875 reflects this engineering approach through balanced performance, high MTBF targets, and enterprise security controls.
