The Xbox Series X contains a UHD Blu-ray Disc drive. In truth, much of the confusion on this subject is due to similarities between the Series X and Series S. It is actually one of three fundamental differences between the two consoles. In addition to the disc drive, the Series X displays games in native 4K and has 1TB of custom SSD storage.

The Xbox Series X ships with a 1TB internal SSD drive, while the Xbox Series S features a reduced 512GB capacity out of the box. In reality, Xbox Series X has just 802GB of space usable for games, with Xbox Series S offering just 364GB.

Microsoft is planning to ditch the disc drive in the Xbox Series X console next year, instead offering gamers 2TB of internal storage for digital games. As The Verge reports, the new console was accidentally revealed in FTC v. Microsoft documents, and the changes to the console go well beyond just removing the drive.
