Xbox Series X might finally get a cheaper storage expansion card

A new storage expansion card for Xbox Series X and S was spotted over the weekend at Best Buy, but has since been removed from the store. This option from Western Digital's WD_Black brand would be the first official competitor to the Seagate Expansion Card, which has been available since the earliest days of the console.

The Seagate Expansion Card is by far and away the best Xbox Series X hard drive because it's the closest thing the platform has to an additional internal SSD. The card slots into a small port in the back of either console, resembling the design of a PS2 memory card, and offers more storage for new-gen and last-gen games.

Perhaps most interestingly, the WD_Black card was priced cheaper than Seagate's, which you'll struggle to find any cheaper than $210. The removed listing said the WD_Black C50, which hasn't been officially announced, would cost $179.99 - a whole $40 less for the 1TB model.

It's not clear at the moment when this storage expansion will be available for purchase, and what capacities will be on offer. The Best Buy listing was for the 1TB version, and we've seen 500GB and 2TB variants of the Seagate Expansion Card.

A new manufacturer creating a competitive price battle is just what the Xbox storage market needs, however, as the cost of Seagate's Expansion Card hasn't shifted much since launch. This is despite the fact that the best SSDs for gaming have been seeing record-low offers for more than a year now.

That said, since the C50 listing was spotted over the weekend, Best Buy has reduced the Seagate model to only $189.99.

The Xbox Series X and S do not have internal M.2 slots for PCIe Gen 4 SSDs like the PS5 does. This means beyond the Seagate card, only the best external hard drives will work as additional game storage for Xbox users. Since even external SSDs aren't able to launch new-gen games, having only one option for additional storage makes things more difficult.

Meanwhile, the best PS5 SSDs are all internal and come from a range of manufacturers, making it easy for Sony's adopters to get storage solutions for cheap prices.

Ever since playing Journey at the age of 15, I’ve been desperate to cover video games for a living. After graduating from Edinburgh Napier University with a degree in Journalism, I contributed to the Scottish Games Network and completed an Editorial Internship over at Expert Reviews. Besides that, I’ve been managing my own YouTube channel and Podcast for the last 7 years. It’s been a long road, but all that experience somehow landed me a dream job covering gaming hardware. I’m a self-confessing PlayStation fanboy, but my experience covering the larger business and developer side of the whole industry has given me a strong knowledge of all platforms. When I’m not testing out every peripheral I can get my hands on, I’m probably either playing tennis or dissecting game design for an upcoming video essay. Now, I better stop myself here before I get talking about my favourite games like HUNT: Showdown, Dishonored, and Towerfall Ascension.
