The Xbox Series X is the successor to the Xbox One. This Series X has a disc tray, which allows you to play all your games on CD. This also applies to most of your Xbox One games, because the Xbox Series X is backwards compatible. This Xbox has a lot of new features compared to its predecessor. The Xbox Series X uses NVMe SSD storage, so the loading times are shorter than ever. In addition, the console supports DirectX ray tracing, so games look even better. The refresh rate is now 144 fps when you game in Full HD or Quad HD. If you game in 4K, it has a maximum refresh rate of 120Hz. As a result, there are no lags and the gameplay looks smooth. This depends on the game you're playing. In addition, you can easily expand the console's memory with an expansion card. This is a card that you plug into the Xbox and expand the storage with the size of the expansion card. This gives you more space to save your games and download updates.
