Description

The WD Black SN770 NVMe SSD 1TB is a compact M.2 2280 form factor drive with a formatted capacity of 1 TB. It utilizes a PCIe Gen4 x4 interface, enabling blazing-fast sequential read speeds of up to 5,150 MB/s and sequential write speeds of up to 4,900 MB/s. This drive is purpose-built to reduce game load times, minimize in-game stutter, and provide a smooth, responsive gaming and creative experience.

While it is a DRAM-less design, it compensates effectively by leveraging Host Memory Buffer (HMB) technology, which allows it to use a portion of the system’s RAM for essential mapping data, thereby maintaining high performance. The drive is also highly power-efficient, with WD claiming up to 20% more power efficiency at maximum speed compared to the previous generation, making it a good choice for gaming laptops. It supports Microsoft’s DirectStorage API, a key feature for future games that will further accelerate load times. The drive’s health and performance can be monitored using the downloadable WD Black Dashboard software. The SN770 is backed by a 5-year limited warranty and has a robust endurance rating of 600 TBW (Terabytes Written).
