## Long description

The Western Digital Black SN8100 4 TB M.2 PCIe 5.0 SSD delivers PCIe Gen5 performance for gaming, content creation, and AI workloads. This NVMe M.2 drive uses advanced TLC 3D CBA NAND and nCache 4.0 to provide high sequential and random throughput, while a custom low-profile heatsink with anodized aluminum construction and customizable RGB supports passive cooling without extra fans. Available up to 4TB capacity, the SN8100 combines high performance, power efficiency, and endurance for demanding systems.
Advantages
PCIe® Gen5 x4 NVMe™ interface enables extremely high sequential read and write speeds, with peak sequential read speeds up to 14,900 MB/s and write speeds up to 14,000 MB/s on higher-capacity models. The drive uses TLC 3D CBA NAND and nCache™ 4.0 to balance speed and reliability. It offers improved power efficiency compared with PCIe Gen4 designs, with typical operating power around or under 7W, and endurance up to 2,400 TBW (4TB model). The integrated anodized aluminum heatsink provides passive thermal management and customizable RGB lighting while keeping noise and additional power needs to a minimum.
Suitable for
High-level gaming and fast game library loading
Professional content creation and video editing
AI model loading and inference workloads
Large datasets, caching, and workstation applications
