Xbox Series expansion card prices
An Xbox Series expansion card is a small storage drive that plugs into the dedicated expansion slot on your Xbox Series X or Xbox Series S. It gives you more room for games, and it's built to run them the same way the console's internal storage does. On PartsPrices we compare the 1 TB and 2 TB versions. Before you buy, check the form factor (this is a proprietary card, not a standard NVMe SSD), the interface (the dedicated expansion slot), and compatibility with your specific console.

Fits these devices
Before you buy
- Match the size to your habits. If you keep a large library installed at once and don't like deleting and re-downloading games, the 2 TB version gives you more breathing room. If you usually rotate through a handful of titles, the 1 TB version may be all you need.
- Double-check the form factor. This card is designed for one specific slot on Xbox Series X and Xbox Series S. It won't work in a standard NVMe slot in a PC, in a USB enclosure, or in any other console, so make sure you're looking at an expansion card and not a generic drive.
- Think about whether you need a card at all. Xbox Series X|S optimized games need to live on the console's internal storage or on one of these cards. Older Xbox, Xbox 360, and original Xbox games can usually run from a regular USB external drive, which may be all you need if that's what you play.
Questions
Will this expansion card fit my console?
It plugs directly into the dedicated expansion card slot on Xbox Series X and Xbox Series S—no cables and no tools. In our catalog, it's listed as compatible with Microsoft Xbox Series X|S. It will not fit a standard NVMe slot, a USB port, or any other device, so check that your console is one of these before you order.
Is an expansion card as fast as the internal storage?
It's designed to deliver the same experience as the console's internal storage, which is why you can run Xbox Series X|S optimized games straight from the card. You don't have to move games back to the console to play them, and you don't need a separate transfer step.
Should I buy new or used?
Both can work, so go with what you're comfortable with. If you buy used, check the item's condition, confirm it's a genuine card for Xbox Series X|S, ask whether any warranty still applies, and make sure you can return it if it doesn't work with your console. A new card gives you a clean start and full manufacturer support.
How much capacity do I need, 1 TB or 2 TB?
Count how many games you like to keep installed at the same time. Modern games often take up tens of gigabytes each, so a full library adds up quickly. If you routinely have a dozen or more large games installed, the 2 TB version will save you from constant deleting and re-downloading. If you play a small rotation, 1 TB is usually a comfortable fit.
