About the WD Blue SN5100 4TB M.2 PCIe Gen4 NVMe SSD
Part number WDS400T5B0E delivers 1,600 TBW endurance, making this Western Digital enterprise SSD a proven choice for write-intensive storage workloads. The WD Blue SN5100 combines PCIe Gen4 x4 speed with 3D NAND architecture to meet the demands of data centers, virtualization platforms, and high-throughput applications. With sequential read speeds up to 5,150 MB/s and write speeds up to 4,900 MB/s, this 4TB M.2 2280 form factor drive accelerates database operations, content delivery, and real-time analytics without sacrificing reliability.
Storage architects and IT procurement teams will appreciate the Host Memory Buffer (HMB) cache architecture—eliminating the need for dedicated DRAM while maintaining performance. Western Digital engineered this drive to operate across 0°C to 70°C, with storage capability from -40°C to 85°C, ensuring compatibility with diverse enterprise environments. NVMe 1.4 protocol support and M-key connector design guarantee seamless integration into modern server and workstation platforms. Windows 10/11 and Linux support, coupled with WD Dashboard management software for health monitoring and firmware updates, simplify deployment and lifecycle management. The single-sided PCB design reduces board complexity while the M.2 bus-powered interface eliminates external power requirements.
Enterprise Deployment Scenarios
- High-performance virtual machine datastores requiring sustained write throughput and endurance rated for multi-year operation
