Here's an interesting one. A modder has claimed to have transformed an internal SSD into a handy expansion card for the Xbox Series X|S. While they've only been able to replicate the theory once, they believe other SSDs could be used similarly.
As spotted by VGC, an author on the Chinese website known as BiliBili has come forward with how they've managed the impossible. The idea came when watching a teardown video of the next-gen systems, which showed the system used two PCIe 4.0 x2 slots - one was for the internal NVMe SSD storage, while the other operated the Seagate expansion card.
Using a 1TB Western Digital SN530 m.2 2230 SSD, it was connected to a CFe to NVMe adapter. The reason being is that this particular SSD is said to be the same used internally within the Xbox Series X|S console. The end result seems to have been a success.
Once the connections were all completed, the site claims the console recognised the SSD once it was inserted into the back of the console, offering an extra 867GB worth of storage in the process. Although, it is worth pointing out that the site isn't sure whether SSDs that aren't used in the console internally will work.
BiliBili claims "someone tried inserting their camera card (CFexpress Type B, PCIe 3.0 x2, 2000MB/s) into the Xbox and got an incompatible pop-up", so it's clear it doesn't connect with everything. While the process of doing this perhaps isn't ideal for most people, it is an interesting sight into what can be done if you have the means to do so.
