WD_BLACK SN850 2TB Gen4 NVMe SSD Alternatives: 6 Similar Picks Compared

How these alternatives compare

WD_BLACK SN770 2TB Gen4 NVMe SSD

The WD_BLACK SN770 2TB Gen4 NVMe SSD shares the same M.2 2280 form factor and 2TB capacity as the SN850. It targets gamers who do not require the absolute highest tier of speed. While it lacks the specific 3D NAND specification listed for the SN850, it offers a practical balance of capacity and value. You should pick this drive if you prioritize storage space and cost efficiency over maximum throughput. It fits standard desktop and laptop builds without requiring extra cooling components. This model is ideal for users who want reliable Gen4 performance without paying for peak bandwidth that many games do not fully utilize.

WD_BLACK SN850X 2TB NVMe SSD with Heatsink

The WD_BLACK SN850X 2TB NVMe SSD with Heatsink offers a convenient built-in cooler, distinguishing it from the bare SN850. It retains the high-speed Gen4 performance expected from the SN850 line but adds thermal management in a single package. The physical dimensions are larger due to the heatsink, measuring 4 inches in width and 1 inch in height. You should choose this option if you want high performance without sourcing a separate cooling solution. It is particularly useful for systems with limited airflow or for users who prefer a cleaner installation. The included heatsink helps maintain consistent speeds during intensive gaming sessions or large file transfers.

Sandisk WD_Black SN7100 2TB Gen4 SSD
