Overview
- SanDisk listed three Optimus GX C50 Expansion Cards on its website on Monday in 512GB, 1TB and 2TB sizes, but each page shows a “Notify Me” button rather than firm release dates.
- The product pages state the cards use Xbox Velocity Architecture to match the console’s internal SSD speeds so players can run optimized games directly from the cards.
- SanDisk published launch prices of $109.99, $199.99 and $339.99 for 512GB, 1TB and 2TB respectively while also showing higher struck-through MSRPs that suggest those lower figures could be temporary.
- SanDisk becomes the third branded supplier after Seagate and WD Black, which may ease stock shortages but is unlikely to force sustained price cuts because memory and storage component costs have risen.
- The route to this market matters: Xbox uses a proprietary expansion card form factor to preserve internal SSD performance, a constraint that keeps these officially licensed cards pricier than generic external drives and shaped the market since Seagate’s 2020 launch and WD’s 2023 entry.
