0TS2458

Enterprise 2.5in U.3 Dual-Port NVMe SSD optimised for low-latency mixed workloads with the 0TS2458

The 0TS2458 is a WD Ultrastar DC SN655 enterprise NVMe SSD designed to accelerate mixed read-intensive tiers in modern servers and workstations where predictable latency and deterministic data paths matter. Built on 3D TLC NAND and a PCIe NVMe architecture, it enables high queue-depth efficiency and fast metadata operations that improve database and virtualisation responsiveness without overprovisioning capacity.

With a 2.5in U.3 form factor and dual-port capability, 0TS2458 supports high-availability designs by maintaining access continuity across redundant paths, aligning with enterprise backplanes and NVMe-oF target configurations. The 3.84TB capacity is paired with endurance rated at 1 DWPD for 5 years, positioning 0TS2458 as a balanced NVMe tier for transactional datasets, VDI images, and consolidated storage pools where write bursts exist but sustained write duty remains controlled.

Why Choose the 0TS2458?

The 0TS2458 delivers a strong density-to-performance ratio in a serviceable 2.5in footprint while providing the reliability profile required for always-on infrastructures. Dual-port connectivity improves scalability for clustered platforms and reduces single-path exposure, enabling cleaner deployment logic for HA nodes, shared flash pools, and mission-critical boot or caching layers.

WD engineers the Ultrastar portfolio around data centre operational continuity, focusing on consistent QoS, power-fail protection, and validation against enterprise storage standards. For 0TS2458, this translates into predictable behaviour under load, long service life targets, and integration readiness for secure lifecycle management across heterogeneous server fleets.

Key Applications:

Database NVMe tiering
Virtualisation and hyperconverged infrastructure
VDI and workspace infrastructure
NVMe caching and acceleration
Secure compliant storage deployments
