We tested two external USB SSDs on Microsoft’s Xbox Series S. How do these drives stack up against the console’s next-gen internal SSD?

Fast next-gen console storage is precious and with Microsoft’s entry-level console only sporting 512GB of space (of which only 364GB is actually usable), many Xbox players will be looking out for fast additional storage to play their backward-compatible titles from. Microsoft has partnered up with Seagate for its officially-licensed Xbox Series X|S Storage Expansion Card. This NVMe storage card, however, doesn’t come cheap and while users will also be able to play next-gen Xbox Series X|S titles from it, there are plenty of Xbox players who are looking for extra space to only play their backward-compatible titles from.
