A swanky new SSD is a vital bit of kit for any PS5 owner looking to expand their console's storage capacity, and Western Digital has been right up there as one of the most popular choices right from the off. The company was the very first to announce a PS5-ready SSD back in October 2020, and its WD_Black SN850 range has proven to be such a solid choice that Sony has officially endorsed it for its new-gen system.

While the SN850 has always been one of the most popular picks in our full guide to the Best PS5 SSDs, Western Digital is taking things a step further with the SN850X, an upgraded model of the SN850 that looks to be yet another fantastic option.

In a blog post, WD_BLACK product marketing manager Luis Tenorio says, "The first thing we did for the 850X is we squeezed a little bit more performance out of the drive. This is a PCIe Gen 4 dive, so we can theoretically get to an 8000 MB/s read speed. We are so close to the limits of PCIe Gen 4, and we can’t really push [the drive] much farther than we have with the 850X, so we’re looking to add features."

You can grab one below if you're interested – the 1TB and 2TB versions can be purchased with or without a heatsink included, while the 4TB model only comes without. We'll drop some product info for you just below these links:
