Overview

The WD Black SN850X is an M.2 SSD rated for use in laptops and desktops. Right now at Best Buy you can save 53 % on the 4 TB model, bringing the price down to $800—a discount of over $900 and closer to pre‑AI pricing.

Also: The best M.2 SSDs you can buy

The SN850X is also available in 1 TB, 2 TB, and 8 TB capacities, each with its own steep discount. All versions feature read and write speeds of 7,300 MB/s and 6,600 MB/s, respectively, delivering faster game loading, quicker app launches, and snappier file access.

Also: SSD vs. HDD

Tailored for premium gaming, the WD Black SN850X includes predictive loading to keep frequently used assets ready for faster load times. It is rated for read and write endurance up to 2,400 TB, meaning the drive could be filled roughly 600 times before any reliability concerns arise.

How I rated this deal

Whether the AI bubble has finally popped or Best Buy is simply moving stock, a 53 % discount on a 4 TB SSD is a deal too tempting to pass up. If your PC or laptop needs a storage upgrade but has been held back by high SSD prices, this $800 price point is much closer to pre‑AI costs than we’ve seen in a long time. For that reason, I gave this deal a 5/5 Editor’s rating.
