One of the most welcome features of the Xbox Series X/S is the ability to easily add more solid-state drive capacity with simple plug-and-play expansion cards. Unfortunately, thus far there hasn’t been much (or any) choice when it comes to these cards – a $220 Seagate 1 TB SSD Expansion Card is your only option at the moment. Thankfully, that’s about to change.

Microsoft has announced that 512 GB and 2 TB Seagate SSD Expansion Cards will be available this holiday season. The 512 GB card will offer a bit of a price break, as it will only cost $140. Meanwhile, the 2 TB card is only for you high rollers, as it will cost $400 – a hundred bucks more than an Xbox Series S!
