Seagate has been producing high-quality SSDs for Xbox consoles for many years to help players create more storage space for their favorite Xbox titles.

One of company's most premium SSDs it has made in recent years is the Seagate 4TB Storage Expansion Card, the world's first 4TB expansion card made for Xbox Series X|S.

Aside from its massive storage space of four terabytes, this device is packed with all the advanced features that made the standard 1TB model one of the best SSD for Xbox consoles.

This features include easy-to-use plug and play operation via the CFExpress standard (just simply plug into the back of an Xbox dedicated SSD slot and it's ready for use) and PCIe Gen 4 technology so it can fast reading speeds to run games flawlessly from the card.

On top of that, the 4TB Seagate Storage Expansion Card for Xbox has a compact design that makes it easy to store in carrying bags, backpacks, or coat pockets while travelling.

What's more is that this device is currently the Seagate's 4TB Storage Expansion Card is the only one of its kind as this writing as other expansion cards like the WD_BLACK Xbox Series X|S Expansion Card can only go up to 2TB.

However, there is a major downside to having 4TB of storage space and advanced technology and is its MSRP of $499.99. With such a high cost, it would practically cost you an arm and a leg to a hold of one of these 4TB expansion cards.

Additionally, 4TB is too over-the-top if you're planning on only storing games instead of playing them directly from the card, in which you need one of the best Xbox external SSDs like the Western Digital Black P50 Game Drive.

Not to mention only a few games available right would require over 1TB of installation to warrant such storage space demands like Call of Duty: Black Ops 6 or Final Fantasy XVI.

FAQ

What is the Seagate 4TB Storage Expansion Card?

It’s an officially licensed NVMe SSD designed in partnership with Xbox to expand your Series X|S storage. It slots into the console’s proprietary expansion port and delivers the same speed, features, and responsiveness as the internal SSD.

Yes! Thanks to full support for Xbox Velocity Architecture, you can run optimized titles directly from the card with identical load times, Quick Resume functionality, and performance as the internal drive.

How much storage does the 4TB model actually provide?

After formatting and system allocation, usable capacity is slightly less than 4TB — but still enough to store hundreds of modern games, including large AAA titles that exceed 100GB each.

Is it portable between consoles?

Absolutely. The card is hot‑swappable, so you can move it between Xbox Series X and Series S consoles instantly, keeping your installed games and saves intact.
