With both the Xbox Series X and the PlayStation 5 using proprietary SSD solutions for internal storage, there has been some question as to how players can expand the available space. For the Xbox Series X at least, Microsoft has a solution, and it's working with hard-drive manufacturer Seagate to do it.
The Xbox Series X ships with a 1TB internal SSD, but can be expanded using proprietary SSDs encased in small metal cartridges. Microsoft explained to Digital Foundry how these small SSDs will work as part of their new "Velocity Architecture"--a new way for developers to utilize SSD memory as standard RAM to store game assets on the fly, and access them with minimal speed compromises.
Microsoft was displeased by the speed compromises of most SSDs when heating up, and worked with Seagate to produce a form factor that provided thermal dissipation while also ensuring a steady 2.4GB/s throughput that developers can depend on. This works in tandem with custom hardware within the console that allows developers to use the SSD to access game files instantly at any point during rendering.
