Storage Size
Both of the new Xbox consoles will feature NVME Gen 4 SSDs that have theoretical read/write speeds of up to 3.75 GB/s. While it’s not as ridiculous as the PS5 target of 5 GB/s, the Xbox SSD read/write performance is still a massive improvement over the current generation of storage hardware that tops out around 100 MB/s.
Although the SSDs used in Xbox Series X and Series S have the same speeds, their storage sizes differ greatly. Series X gives you 1 TB of storage and Series S offers just over half that amount at 512 GB of storage. As games increase in size and digital sales expand, this difference may become a deal-breaker.
We already know that there will be proprietary external storage for Series S and Series X, but that starts to lessen the overall value of Microsoft’s all digital option. If you don’t mind having to uninstall titles regularly, then this storage size difference won’t be that big of an issue.
