0TS2461

High-Performance 2.5-inch U.3 NVMe Datacenter SSD with dual-port HA connectivity using the 0TS2461

The 0TS2461 is a WD Ultrastar DC SN655 datacenter SSD engineered for U.3 NVMe backplanes where low-latency boot, caching tiers, and consistent mixed workloads are operational priorities. Designed around 3D TLC NAND and a dual-port enterprise NVMe architecture, the 0TS2461 supports resilient host connectivity for platforms that cannot tolerate single-path failure in clustered storage and virtualization stacks.

With PCIe NVMe throughput aligned to modern server I/O fabrics, the 0TS2461 sustains strong sequential and 4K performance while keeping write endurance predictable at 1 DWPD over 5 years. Its 3.84TB capacity fits dense 2.5-inch bays for scale-out nodes, and the U.3 form factor simplifies integration across mixed SAS/SATA/NVMe chassis designs. Power Loss Protection preserves in-flight data during unexpected outages, making the 0TS2461 suitable for write-intensive metadata, VM density improvements, and caching layers that must remain consistent under failure scenarios.

Why Choose the 0TS2461?

The 0TS2461 delivers a balanced density-to-performance profile for enterprise deployments that require dual-port NVMe high availability without expanding chassis footprint. It scales cleanly in NVMe SAN designs and HA storage nodes, while providing the reliability characteristics expected in always-on infrastructure, including predictable endurance behavior and robust data-path protection.

WD focuses on datacenter-grade engineering with controlled firmware behavior, qualification for enterprise platforms, and lifecycle alignment to modern data centre standards. The drive’s security features, including AES-256 encryption and Instant Secure Erase, support operational governance while maintaining serviceability in large fleets.

Key Applications:

Server boot and caching tiers
Mixed read/write databases
Virtualization storage
NVMe SAN
HA storage nodes requiring dual-port

At Happyware - Server Hardware you benefit from non-binding offers tailored to your environment, helping you standardize the 0TS2461 across clusters and refresh cycles, and you can extend the warranty up to 6 years to protect long-lived storage architectures.
