WD Black SN850X 4TB M.2 PCIe 4.0 Gen4 x4 NVMe SSD
The WD Black SN850X 4TB M.2 PCIe 4.0 Gen4 x4 NVMe SSD is a high-performance solid-state drive designed for use in high-end computing systems such as gaming PCs, workstations, and servers. It is built using the latest PCIe 4.0 interface and NVMe protocol, which allows for faster data transfer rates than traditional SATA-based SSDs.
With a capacity of 4TB, this drive offers ample storage space for large files, such as high-resolution images, videos, and games. It also features advanced technologies such as Western Digital's own controller and firmware, which help to optimize performance and improve reliability.
The SN850X uses a M.2 form factor, which makes it easy to install in compatible motherboards and laptops that support this form factor. It also features a sleek and stylish design with a black heatsink, which helps to dissipate heat and keep the drive cool under heavy loads.
