What makes the Optimus GX C50 different
The key point is that the Optimus GX C50 isn’t positioned as a standard external USB storage drive. Instead, it’s meant to sit in the console’s dedicated expansion slot, where it can be used with Xbox Velocity Architecture.
That matters because many games built for the current generation can’t be run directly from typical external USB SSDs or hard drives. With a proper expansion card, you can install those titles and launch them from the added storage without moving everything back to the internal SSD first.
Direct install, no console opening
Installation is straightforward: you connect the Optimus GX C50 to the expansion slot on Xbox Series X|S, and the system recognizes the added capacity. There’s no need to open the console or perform any internal hardware installation.
SanDisk also bundles two subscription perks with the card: a month of Xbox Game Pass and a month of Discord Nitro.
Competition heats up in Xbox expansion storage
SanDisk’s entry widens the list of manufacturers in a market that has historically had few options. For a long time, Seagate dominated the space, and Western Digital later joined with its WD_BLACK C50.
At €299.99 for 2TB, the Optimus GX C50 is still a serious purchase, but it’s also designed to bring a large capacity bump—effectively doubling available storage on a standard Xbox Series X—while preserving the benefits of internal-like expansion support.
With modern releases often exceeding 100GB, extra room for simultaneously installed games can make a noticeable difference for players who want fewer uninstall/reinstall cycles.
