0TS1963 WD Ultrastar DC SN640 7.68TB U.2 NVMe 2.5" Server SSD

High-Density U.2 NVMe Datacenter SSD for Read-Optimized Server Storage with the 0TS1963

The 0TS1963 is a WD Ultrastar DC SN640 enterprise datacenter SSD engineered for PCIe NVMe storage tiers where consistent latency and predictable read performance are critical for boot, application, and virtualization volumes. In a 2.5in U.2 form factor, the 0TS1963 supports hot-swap serviceability in modern server backplanes, enabling maintenance without disrupting clustered workloads.

Built on TLC NAND with power-loss protection, the 0TS1963 targets read-optimized deployment profiles while maintaining controlled endurance at 0.8 DWPD for 5 years. NVMe parallelism and queue depth efficiency translate into strong sequential throughput up to 3,250 MB/s read and responsive 4K access up to 467K read IOPS, aligning well with hypervisor boot storms, catalog lookups, and application-heavy VM images. AES-256 hardware encryption and Secure Erase support secure lifecycle management across multi-tenant or regulated environments.

Why Choose the 0TS1963?

The 0TS1963 delivers an enterprise-ready density-to-performance balance for U.2 NVMe platforms, combining hot-swap operational continuity with reliability characteristics suited to 24x7 infrastructure. With power-loss protection and consistent QoS behavior, the 0TS1963 scales cleanly from single-server boot pools to dense VM datastore tiers without introducing complex controller dependencies.

WD designs Ultrastar datacenter SSDs with a validation-first engineering philosophy focused on predictable behavior under sustained load, long service life, and integration with current server storage standards. The 0TS1963 aligns with enterprise requirements for security, endurance governance, and fleet reliability, backed by a 2.0 million hour MTBF specification.
