0T00835 WD Ultrastar SN100 800GB NVMe 2.5" Server SSD

High-Performance 2.5in U.2 NVMe Enterprise SSD for mixed-IO tiers with the 0T00835

The 0T00835 is a WD Ultrastar SN100 800GB 2.5in U.2 NVMe hot-swap SSD engineered for enterprise server boot volumes and accelerator-tier storage where predictable latency matters. By using an NVMe protocol stack over PCIe, it reduces command overhead versus legacy SATA/SAS designs, improving queue-depth efficiency for mixed read/write workloads typical of virtualised infrastructure and container hosts.

Architecturally, 0T00835 aligns to PCIe-based backplanes and U.2 hot-swap bays to support serviceability without downtime. Its MLC NAND and 3 DWPD endurance profile target write-intensive caching, metadata, and log streams, while Power Loss Protection helps preserve in-flight data during power events. With up to 2600 MB/s read and 1400 MB/s write throughput and 4K performance up to 634K read and 80K write IOPS, 0T00835 is suited for consolidating boot, journal, and cache tiers while keeping expansion slots available for NICs, HBAs, and accelerators.

Why Choose the 0T00835?

The 0T00835 provides a strong density-to-performance ratio in a standard 2.5in U.2 footprint, enabling scale-out nodes to standardise on hot-swap NVMe without sacrificing maintainability. For 24x7 deployments, 0T00835 supports consistent service levels with enterprise endurance, a 2.0M-hour MTBF, and PLP-driven resilience, making it a pragmatic building block for repeatable server configurations and fleet-wide lifecycle management.

WD’s enterprise storage engineering emphasises sustained workload behaviour, qualification for modern data centre backplanes, and reliability features designed for continuous operation, helping infrastructure teams align media choice with operational risk controls and platform standards.
