0TS1841 WD Ultrastar DC SN620 1.6TB U.2 NVMe 2.5" Server SSD

High-Performance 2.5in U.2 NVMe Datacenter SSD featuring hot-swap serviceability with the 0TS1841

The 0TS1841 is a WD Ultrastar DC SN620 1.6TB NVMe datacenter SSD engineered for PCIe-based storage planes where predictable latency, controlled endurance, and operational security are primary design requirements. Deployed as a boot and application device in NVMe backplanes, the 0TS1841 supports 24/7 duty cycles and aligns well with read-intensive server storage patterns found in virtualized hosts and cache-tier architectures.

Architecturally, the 0TS1841 leverages an enterprise NVMe controller and MLC NAND to balance write amplification control with consistent response under mixed I/O. Sequential throughput up to 1700 MB/s read and 1100 MB/s write, combined with 4K random performance up to 250K read IOPS, makes the 0TS1841 suitable for database caching, metadata services, and dense VM fleets where queue depth and parallelism are critical. Power Loss Protection safeguards in-flight data, while the 2.5in U.2 hot-swap form factor streamlines replacement without disrupting front-access service procedures.

Why Choose the 0TS1841?

The 0TS1841 delivers an efficient density-to-performance profile for NVMe backplanes, pairing 1.6TB capacity with 1.7 DWPD endurance and a 2.0M-hour MTBF to support standardized enterprise lifecycle planning. By combining hot-swap maintainability, consistent read-centric performance, and integrated security controls, the 0TS1841 scales cleanly from single-node boot roles to multi-node virtualization clusters with uniform operational behavior.

WD designs Ultrastar datacenter media with a focus on reliability engineering, firmware validation, and interoperability for modern rack server and storage platforms. The 0TS1841 follows enterprise standards for secure deployment, serviceability, and continuous operation in controlled data centre environments.
