0TS1930 WD Ultrastar DC SN640 7.68TB NVMe 2.5" Server SSD

High-Density 2.5in U.2 NVMe Enterprise SSD for Hot-Swap Server Storage with 0TS1930

The 0TS1930 is a WD Ultrastar DC SN640 7.68TB enterprise datacenter SSD engineered for NVMe server bays where low latency, predictable read performance, and serviceability are mandatory. In 2.5in U.2 form factor, 0TS1930 integrates cleanly into hot-swap backplanes and standard drive carriers, aligning with modern x86 server platforms that route storage through PCIe for reduced protocol overhead versus SATA/SAS.

Built on TLC NAND with an endurance profile of 0.8 DWPD over 5 years, 0TS1930 targets boot volumes, read-intensive application tiers, and mixed enterprise workloads that require consistent QoS under 24/7 operation. PCIe NVMe connectivity supports fast queueing and parallelism, translating to up to 3,250 MB/s sequential reads and up to 467k 4K random read IOPS for VM fleets and metadata-heavy services. Power Loss Protection helps preserve in-flight data during unexpected events, while AES-256 and Instant Secure Erase (ISE) support secure decommissioning workflows.

Why Choose the 0TS1930?

The 0TS1930 delivers an efficient density-to-performance ratio for 2.5in U.2 server slots, enabling capacity scaling without changing chassis or cabling. With enterprise reliability targets including 2.0M hours MTBF and hot-swap operability, 0TS1930 supports standardized spares strategy, rapid replacement, and predictable lifecycle management across clustered nodes.

WD designs the Ultrastar line for datacenter duty cycles, focusing on controlled latency behavior, power integrity safeguards, and security primitives aligned with enterprise compliance. This engineering approach helps the 0TS1930 remain stable under continuous workloads and integration into validated server storage architectures.
