0TS1842 WD Ultrastar DC SN620 1.92TB NVMe 2.5" Server SSD

Enterprise 2.5-inch U.2 NVMe Datacenter SSD with Power-Loss Protection and Encryption using the 0TS1842

The 0TS1842 is a WD Ultrastar DC SN620-class enterprise NVMe SSD designed for consistent low-latency storage tiers in rack servers and HCI nodes, where predictable QoS matters more than peak burst throughput. Built on a PCIe NVMe architecture in a 2.5-inch U.2 hot-swap form factor, it integrates cleanly into modern backplanes and service models, enabling rapid replacement without taking a node out of production.

With 1.92TB of MLC NAND and a read-optimised endurance profile, the 0TS1842 aligns to boot, cache, and read-heavy mixed workloads that require moderate write capability over a 5-year service life. Power Loss Protection preserves in-flight data during unexpected power events, while SED with 256-bit AES and Instant Secure Erase supports controlled decommissioning and secure reuse within enterprise governance. The platform-level benefit of the 0TS1842 is simplified expansion via standard U.2 NVMe bays, keeping PCIe lanes available for accelerators, NICs, and other I/O while maintaining efficient storage density.

Why Choose the 0TS1842?

The 0TS1842 delivers a pragmatic density-to-performance ratio for datacenter boot and caching tiers, combining hot-swap serviceability with enterprise reliability for 24x7 operations. It scales cleanly across homogeneous server fleets, supports repeatable deployment images, and reduces operational risk through PLP and hardware-based encryption, making it suitable for clustered nodes where downtime and data exposure are unacceptable.

WD designs Ultrastar-class storage with a focus on sustained datacenter duty cycles, qualification for standardized server and backplane environments, and predictable lifecycle behavior. The 0TS1842 follows this engineering approach by pairing controlled endurance characteristics with security and data-protection features aligned to modern operational and compliance requirements.

Key Applications:

• Server boot and OS volumes
• Read cache tiers for virtualisation
• HCI node caching and metadata
• Content delivery and edge caching
• Secure decommissioning workflows
