0TS1639 WD Ultrastar DC SN630 3.2TB PCIe Gen 3 2.5" Server SSD

High-Density 2.5in U.2 NVMe Datacenter SSD for Read-Intensive Tiers with the 0TS1639

The 0TS1639 is a 3.2TB internal datacenter NVMe SSD in a 2.5in U.2 form factor, designed for servers requiring consistent low-latency storage without sacrificing bay density. Using a PCIe Gen3 NVMe interface, the 0TS1639 aligns well with established enterprise platforms where predictable queue handling and efficient parallel I/O matter more than peak Gen4 bandwidth.

Built on 3D TLC NAND, the 0TS1639 targets read-intensive and mixed boot/data tiers with an endurance profile of 2 DWPD over 5 years and a rated 11,680 TBW. Performance up to 2,500 MB/s sequential read and 332,510 4K read IOPS supports VM datastore acceleration and high-density caching, while power-loss protection helps maintain in-flight data integrity during unexpected events. For controlled decommissioning and security operations, AES-256 and Instant Secure Erase provide practical safeguards at the drive level.

Why Choose the 0TS1639?

The 0TS1639 delivers a balanced density-to-performance ratio for enterprise nodes that must scale storage across many bays while keeping latency stable for virtualization and database tiers. The architecture favors predictable read responsiveness, operational endurance headroom, and integration into PCIe Gen3 backplanes, enabling straightforward expansion and standardized sparing across fleets.

WD engineers Ultrastar-class datacenter SSDs around reliability metrics and long service lifecycles, aligning firmware behavior, NAND management, and qualification processes with modern rack-scale deployment standards and uptime expectations.

Key Applications:

• Server boot and mixed data tiers
• Virtualization VM datastores
• NVMe caching layers
• OLTP and indexing workloads
• Analytics staging and scratch
