The latest games need to be installed on the fast internal disks.
This award has also leaked in the past, but now it is official and completely correct.
1TB costs a few bucks
Because we knew 1TB of fast storage for Series X and S was going to be priced around $ 200: the launch price is $ 220.
Norwegian price is not available, but it will probably be around 2100 to 2200 kroner (Xbox Series S costs 3300 kroner, so this is not cheap).
Note that you can not play next-generation games on anything other than this type of official internal disk, or other NVMe PCIe 4.0 products, in order to maintain the speed and experience the developers have aimed for.
Sony's official NVMe list of supported products comes after launch
"Seagate - 1TB Game Drive for Xbox Series X and Series S External Custom PCI Express Gen4 x2 (NVMe) Solid State Drive" is the long product name. The model name is «STJR1000400«.
