High SSD prices got you down? Right now at Best Buy, you can save up to $2,800 on the WD Black SN850P storage drive — perhaps in a bid to compete with Amazon’s Big Spring Sale. And while it’s officially licensed for use with PlayStation 5 consoles, it’s easy to reconfigure for use in gaming laptops and desktops for a boost in storage capacity.

Available in capacities from 1TB to 8TB, the WD Black SN850P can double, or even quadruple, your available storage space, giving you plenty of room for large game downloads, save files, screenshots, highlight reels, and more. With read and write speeds up to 7300 and 6600 MB/s, respectively, you’ll get much faster loading times than traditional HDDs as well as quicker access to your favorite apps, games, and programs.

The integrated heatsink helps keep everything running at optimal temperatures to prevent data loss or corruption due to overheating. It can also be removed for easier installation in smaller PCs. 

By using flash memory rather than traditional mechanical platters, the WD Black SN850P can provide you with years of reliable data access with much less risk of internal damage due to shocks and bumps.

How I rated this deal 

Prices for RAM and SSD storage drives have skyrocketed as AI companies buy up available stock to power LLMs. And while this particular model is licensed for use with the PS5, you can quickly reconfigure it for use in laptops and desktop PCs. The 2TB model is marked down to $400, bringing it closer to pre-AI pricing, and the 8TB version is almost $2,800 off. While it’s still very expensive, it’s the lowest price I’ve seen on a high-end SSD in a long time. That’s why I gave this deal a 5/5 Editor’s rating.
