0TS1879 WD Ultrastar DC SN840 7.68TB U.2 NVMe 2.5" Server SSD

High-Density 2.5in U.2 NVMe Data Center SSD for 24/7 Server Storage with the 0TS1879

The 0TS1879 is a WD Ultrastar DC SN840 enterprise SSD engineered for server boot/media and general-purpose NVMe tiers where predictable latency and continuous duty cycles are mandatory. Built on TLC NAND with a 7.68TB capacity point, the 0TS1879 targets virtualised hosts and cloud nodes that need a balanced read/write profile without sacrificing endurance or operational consistency.

As a 2.5in U.2 NVMe, the 0TS1879 attaches directly to PCIe NVMe backplanes to minimise protocol overhead and improve queue-depth scaling versus legacy SATA/SAS designs. Its hot-swap architecture supports serviceable storage planes and rolling maintenance windows, while sequential throughput up to 3311 MB/s read and 3057 MB/s write aligns well with VM boot storms, log-intensive services, and mixed enterprise application patterns. For transactional workloads, up to 780k IOPS 4K read helps consolidate virtualisation density, and integrated Power Loss Protection protects in-flight data during unexpected power events.

Why Choose the 0TS1879?

The 0TS1879 delivers an efficient density-to-performance ratio for U.2 NVMe bays, enabling higher VM and container consolidation per server while preserving enterprise reliability. With 24/7 operating design, 2.5M hours MTBF, and endurance rated at 1 DWPD for 5 years, the 0TS1879 scales cleanly from single-node boot devices to clustered NVMe capacity pools, simplifying standardisation across mixed workload domains.

WD designs Ultrastar data center media with a focus on sustained performance, controlled power behaviour, and platform compatibility aligned to modern server storage standards. The 0TS1879 integrates Secure Erase capabilities and predictable power states to support operational security and data lifecycle management in enterprise environments.

Key Applications:

• Server boot and OS media
• Virtualisation datastores
• Cloud infrastructure nodes
• Mixed read/write enterprise applications
• Tiered NVMe storage pools
