Looking to upgrade the storage in your desktop PC? Our favorite internal M.2 SSD is marked down with a healthy discount at Walmart, with the 2-TB model marked down to $109, and the 1-TB model marked down to just $64. Those prices are both a fair amount off their regular price, and are even slightly lower than the sale prices at some other retailers. With storage prices at a premium lately, it might be a good time to expand.
WIRED contributor Scott Gilbertson put the SN770 through a battery of tests and found that it reached an impressive 5,100 MB/s. That kind of speed will be perfect for gaming and regular use, and should handle large file transfers with ease. Scott used the drive in his XPS 13 (7/10, WIRED Review) and appreciated that it also managed to keep relatively cool during use, helping offset the slightly older laptop’s otherwise warm operating temperature under load.
Before you click to purchase, you should double-check that your system supports the SN770. This drive uses the M.2 form factor, which is almost like a big flat stick of gum, and it comes in a variety of sizes, with the numbers after indicating the SSD’s dimensions. This particular drive is 2280, which means it’s 22 millimeters wide and 80 millimeters long, which is a common size for both desktops and full-size laptops, but may not fit in all tablets or on smaller motherboards.
If you’re hunting for external drive options, I recommend checking out our very thorough roundup of the best portable hard drives for storage or everyday use, which includes speed and practical testing for a variety of drives.
If you’re in need of a system to put the SN770 inside, the WIRED PC building guide can walk you through every step of the process, complete with product recommendations and tips for making the most of your new system. That said, this is a fantastic deal on one of our favorite hard drives, so it’s great for anyone who needs a few terabytes of solid-state storage.
