That mystery port on the back of Xbox Series X is for expandable storage - report

It looks like Xbox Series X will support expandable storage.

That's according to a report from Thurrott which cites sources close to Microsoft's plans for Xbox Series X.

Initially, it was thought the rectangular port which sets between the HDMI and digital audio port was for diagnostics.

It's unknown at present the technology Microsoft will use for the expandable storage, but the report suggests it will require high-speed hardware.

Digital Foundry's Richard Leadbetter suggested when the back of Xbox Series X first popped up the mystery port was an "expandable storage bay for NVMe PCI Express drives."

Hopefully, Microsoft will reveal more information on the console soon so we'll know for sure.

Until then, here's everything we know about Xbox Seies X at present.
