Western Digital WD_BLACK SN770 1TB M.2 PCIe 4.0 x4 NVMe SSD

The WD_BLACK SN770 is an internal NVMe solid-state drive that utilizes the PCIe 4.0 x4 interface to provide high-bandwidth data transfers. It is constructed in the standard M.2 2280 form factor, ensuring physical compatibility with modern desktop motherboards and portable laptop systems. The drive employs four lanes of PCIe connectivity to facilitate faster system boot times and accelerate the loading of large applications. This storage solution is designed for users requiring consistent throughput for intensive computing tasks without the need for additional cooling hardware.

The drive handles sustained workloads by managing heat through its controller firmware while maintaining a stable connection to the host system. With a slim physical profile of 2.2mm and a total weight of 5.5 grams, it fits into compact builds such as thin laptops or small form factor PCs. The dimensions of 80mm in depth and 22mm in width ensure that the component provides internal storage while maintaining the original cooling airflow of the host machine. Its hardware design is configured for power efficiency and internal temperature regulation during operation.
