Product information

Description

The Western Digital Ultrastar DC SN861 is a U.2 PCIe Gen5 NVMe SSD designed for enterprise servers and data centers. With a capacity of 7.68 TB and PCI Express 5.0 performance, it delivers very high read and write throughput, low latency, and optimized power efficiency for compute‑intensive workloads such as AI and machine learning.

Advantages

This Ultrastar DC SN861 offers PCIe Gen5 speeds, high random read performance, and multiple enterprise features including Power Loss Protection, End-to-End Data Path Protection and TCG security/encryption. It provides high performance per watt to reduce operational power costs, consistent quality of service (QoS) under heavy mixed workloads, and support for modern NVMe standards and OCP 2.0 for scalability.

Suitable for

  • Hyperscale and cloud data centers
  • Enterprise servers and storage arrays
  • Compute‑intensive AI and machine learning workloads
  • Workloads that require low latency and high IOPs/Watt

Key specifications

  • Form factor: U.2
  • Capacity: 7.68 TB (7680 GB)
  • Interface: PCI Express 5.0 (NVMe)
  • Maximum read speed: up to 13,700 MB/s
  • Maximum write speed: up to 7,500 MB/s
  • Enterprise features: Power Loss Protection, End‑to‑End Data Path Protection, TCG security/encryption
  • Standards: NVMe 2.02, NVMe MI 1.2c, OCP 2.0 support
  • Endurance options: 1 & 3 DWPD (device writes per day)
  • Warranty: 5‑year limited warranty

How to use

Install the Ultrastar DC SN861 into a compatible U.2 slot or U.2 carrier on a server or storage chassis that supports PCIe Gen5. Ensure the host platform firmware and drivers support NVMe 2.02 and PCIe 5.0 for optimal performance. Configure the drive in the operating system or storage controller according to your deployment (raw device, RAID, or software-defined storage) and apply any vendor‑recommended firmware updates and security settings.

Usage recommendations

For sustained AI and mixed enterprise workloads, pair the drive with a platform that provides adequate cooling and a PCIe Gen5 host to realize advertised speeds. Use the enterprise features (Power Loss Protection, encryption) and follow vendor guidelines for firmware and QoS tuning to maintain performance and data integrity.
