The WD Black SN850X is an M.2 SSD designed for laptops and desktops, and if you've been avoiding upgrading your PC due to high SSD costs, now is the perfect time to buy. Right now at Best Buy, you can save 65% on the 4TB model, bringing the price to $600. That's a discount of over $1,100, bringing the cost closer to pre-AI pricing.

Is there a catch? Sort of. Not every store has the SSD in stock for shipping, so you'll have to check your nearby locations to see if it's available for pickup. I checked the inventory for various cities throughout the U.S, and still seeing a few available. 

Don't need that much storage space, or do you need more? The SN850X is also available in 1TB, 2TB, and 8TB capacities, each with its own steep discount, so you can choose the version that best suits your needs now and gives you room to grow. 

Each version features read and write speeds of 7300 and 6600 MB/s, respectively, giving you much faster loading times in games, quicker app launches, and easier access to your most-used files. 

Also: Amazon is selling a 2TB Samsung SSD for almost 40% off - and it's seriously fast for PC

The WD Black SN850X is tailor-made for premium gaming, featuring predictive loading to keep the most-used assets ready for faster load times. The SSD is rated for read and write endurance up to 2400TB, which means you can completely fill your drive 600 times over before you have to worry about hardware failure. 

How I rated this deal 

Whether the AI bubble has finally popped or Best Buy is simply trying to move stock, a 65% discount on a 4TB SSD is a deal too tempting to pass up. Especially if your PC or laptop has been in desperate need of a storage upgrade, put off by eye-popping SSD prices. While the price may still be a bit rich for some, at $600, it's much closer to pre-AI costs than I've seen in a very long time. That's why I gave this deal a 5/5 Editor's rating.
