SSD Western Digital Ultrastar DC SN650 U.3 NVMe 7.68 TB PCIe 4.0 (6500/1900 MB/s)

The Western Digital Ultrastar WUS5EA176ESP5E3 is a high-capacity NVMe SSD in a U.3 2.5" form factor that uses PCIe Gen 4.0 and Western Digital BiCS5 TLC 3D NAND to deliver up to 7.68 TB of usable storage. Designed for cloud and scale-out data centers, this drive supports disaggregated storage architectures and is intended to accelerate access to large unstructured datasets for applications such as big data, AI, and machine learning. The drive is built to fit standard U.2/U.3 backplanes and provides enterprise-grade features including power-loss protection and secure erase options.

Advantages

The Ultrastar WUS5EA176ESP5E3 combines PCIe Gen 4.0 performance with high-density BiCS5 TLC 3D NAND to increase storage capacity and throughput while remaining compatible with standard 2.5" U.2/U.3 infrastructures. It offers sustained performance for larger workloads, consistent quality-of-service for multi-host environments, and integrated data protection features such as Power Loss Protection and Secure Erase. The SSD is optimized for maximizing GB-per-watt efficiency in scale-out deployments.

How to use

Install the SSD into a compatible U.3/U.2 bay or adapter on a server or workstation that supports PCIe Gen 4.0 to obtain maximum throughput. Configure the drive at the system or hypervisor level as block storage, or integrate it into object or file storage tiers within a disaggregated or tiered storage architecture. For multi-host environments, ensure your host and backplane firmware and drivers support NVMe and the chosen form factor. Follow your operating system’s standard procedures for initializing, partitioning, and formatting the drive before first use.

Usage recommendations

Use this SSD in scale-out or cloud storage nodes where high capacity, consistent QoS, and fast data movement are required. Maintain current firmware and controller drivers, and perform secure erase when decommissioning the drive. For best endurance and performance, align workload patterns to the drive’s intended use (large sequential and mixed I/O typical for analytics, AI, and ML datasets).
