User discovers that other drives can be converted to work in the card'
"A modder has managed to convert an internal SSD into an external Xbox Series X/S expansion card, and theorises that other non-proprietary SSDs could work too.
At the time of writing, the Xbox Series X/S only has two storage solutions for playing next-gen games: the consoles’ internal SSD, and a proprietary Seagate expansion card that fits into its own port on the back of the console.
A member of Chinese website BiliBili has written a detailed blog on how they managed to buy another external SSD and get it running on the console as if it were the Seagate card.
The user says they discovered while watching a teardown video of the console that it used two PCIe 4.0 x2 slots, one for the internal NVMe SSD storage and another for the Seagate expansion card.
They also noted that the expansion card was a CFExpress card, which also uses the NVMe protocol. They theorised that as long as they could find the right PCIe 4.0 SSD, they could convert it to fit into the expansion card port using an adapter.
The SSD they opted for was a 1TB Western Digital SN530 m.2 2230, because according to the user, this is the same internal SSD that’s actually used in the Xbox Series X hardware (as discovered on other forums in the past).
By connecting this SSD to a CFe to NVMe adapter, the user was able to plug the SSD into an Xbox Series S via the expansion card."
