About This Product
The WD_BLACK SN8100 is a 1TB M.2 PCIe 5.0 x4 NVMe SSD with 1GB of cache. It offers high-speed storage suitable for demanding applications and gaming. While it utilizes the PCIe 5.0 interface, its performance may not significantly exceed high-end PCIe 4.0 drives in typical consumer workloads, especially given current CPU and motherboard limitations. This drive is a premium option for users building new systems with PCIe 5.0 support or those seeking future-proof storage.
