Xbox Storage Just Got Bigger: Seagate Launches Official 4TB Expansion Card
Seagate has officially launched its largest-ever Storage Expansion Card for the Xbox Series X|S , offering a massive 4TB of dedicated storage space — perfect for gamers who are tired of constantly juggling game installations. Priced at $499.99 , this new high-capacity card is now available to purchase, promising a serious boost in onboard storage without compromising speed or performance.
Previously, Seagate offered 1TB and 2TB variants of its official expansion cards, which have been popular among Xbox users looking to extend their console’s internal storage. However, with modern AAA games now regularly exceeding 100GB — and some titles like Call of Duty: Black Ops 6 approaching 400GB — having more space is no longer just a luxury; it’s a necessity.
Why the 4TB Expansion Card Matters
The new 4TB model gives Xbox owners the freedom to:
- Install dozens of next-gen games without worrying about running out of space
- Avoid the hassle of frequently uninstalling and re-downloading titles
- Keep automatic game updates running smoothly , preventing interruptions caused by low storage
Unlike standard external drives, Seagate’s Xbox Velocity Architecture-compatible cards plug directly into the console’s proprietary expansion slot, ensuring full compatibility and maintaining the same ultra-fast load times as the internal SSD.
So while $499 might seem steep compared to traditional NVMe SSDs, the plug-and-play convenience and seamless integration with the Xbox Series X|S ecosystem make this a compelling option for serious gamers.
Just like its smaller predecessors, the new 4TB Seagate Storage Expansion Card is fully optimized for the Xbox Series X|S , delivering the same speed and performance as the console’s internal SSD. This seamless integration allows gamers to play titles directly from the expansion card without needing to transfer them to the system’s internal storage — something that sets it apart from standard external hard drives or even generic NVMe SSDs.
Thanks to compatibility with Microsoft’s Xbox Velocity Architecture , games load faster, textures stream more efficiently, and overall gameplay feels smoother and more immersive. Additionally, many backward-compatible titles run better on this expansion card than they did on their original consoles — offering improved frame rates, shorter load times, and enhanced visuals in some cases.
Same Design, Bigger Capacity
The 4TB model maintains the same compact form factor as the 1TB and 2TB versions, making it just as easy to install and use with either the Xbox Series X or S. It also features the same 128MB cache , ensuring consistent performance across all variants of the expansion card line.
However, this upgrade doesn’t come cheap. The 4TB model is priced at $499.99 , though select retailers like Best Buy are currently offering a $70 discount for a limited time. You can also find it on Amazon (U.S.) , as well as UK-based stores such as Argos, ebuyer, and Scan .
When compared to the price of the base Xbox Series X (1TB) or Series S (1TB) models, the 4TB expansion card costs as much as or more than the console itself — which might give budget-conscious buyers pause.
Is It Worth the Investment?
Despite the high cost, the 4TB Seagate Expansion Card offers a compelling solution for players who:
- Want to keep dozens of large AAA titles installed at once
- Value fast load times and smooth game streaming
- Prefer plug-and-play simplicity over tinkering with external drives
For serious Xbox fans, especially those invested in next-gen gaming, the convenience and performance benefits may justify the expense — making it a worthwhile investment for an uninterrupted gaming experience.
