Microsoft has confirmed that Seagate will be releasing new versions of its storage expansion cards with different capacities for Xbox Series X|S owners who think 1 TB is too much or too little. Available for pre-order now at select retailers, Seagate’s 512 GB and 2 TB Storage Expansion Cards will cost $139.99 and $399.99, respectively. The former will launch in mid-November, while the latter will be available in early December.
From Microsoft:
To use the Seagate Storage Expansion Card, just plug the card into the Storage Expansion port on the back of your Xbox Series X or Xbox Series S console, and you can use it just as you would any external storage solution. You can choose to install games to the expansion card by default, play games directly from it, move or copy games between local and external storage, or do anything you already do today with an external hard drive. The only difference is that the expansion card is designed to match the exact performance of the internal storage of the Xbox Series X|S.
Leveraging the Xbox Velocity Architecture, Seagate’s storage expansion cards offer 2.4 GB/s of raw I/O throughput (more than 40x the throughput of Xbox One) just like the Xbox Series X|S’ internal SSD. The 1 TB version carries an MSRP of $219.99.
