Western Digital (WD / HGST) 3.84TB NVMe U.2 PCIe Gen3 x4 RI SFF 2.5" SSD Ultrastar DC SN640 WUS4BB038D7P3E3
Cisco UCS Compatible (Cisco UCS Drive Tray Included)
The Western Digital Ultrastar DC SN640 WUS4BB038D7P3E3 is a high-performance enterprise NVMe SSD engineered for cloud computing, virtualization, software-defined storage, content delivery networks, and modern data center deployments.
Featuring 3.84TB of enterprise storage capacity, the Ultrastar DC SN640 delivers exceptional reliability, ultra-low latency, and consistent performance for read-intensive workloads. Built with advanced 96-Layer BiCS4 3D TLC NAND Flash, this U.2 SSD utilizes a PCIe Gen 3.1 x4 NVMe 1.3 interface to provide the speed and responsiveness required for mission-critical server applications.
With sequential read speeds of up to 3,100 MB/s, sequential write speeds of up to 1,800 MB/s, and up to 434,000 random read IOPS, the SN640 is optimized for virtualized environments, cloud infrastructure, enterprise databases, and high-density storage platforms.
Designed for enterprise reliability, the drive includes advanced features such as Power Loss Protection (PLP), End-to-End Data Path Protection, Hot-Swap Support, and Instant Secure Erase (ISE). With a 2 million hour MTBF, 0.8 DWPD endurance rating, and 5,744 TBW, this SSD is built to deliver dependable long-term performance.
