Random freezes, missing sound and display glitches usually trace back to one bad driver. Find and replace yours safely.Free scan · under a minuteChoose an Xbox Series X|S expansion card if you want to play optimized Series X|S games directly from added storage. Choose a USB external drive if you mainly want a larger game library, a place to store games, or to play supported Xbox One and earlier titles. A USB drive can hold many optimized games, but most must be moved to the console’s internal storage or an expansion card before you can play them.
Expansion cards and USB drives solve different storage problems
An expansion card connects through the console’s dedicated Storage Expansion port and provides added storage for playing optimized Series X|S games. Microsoft says the Seagate Storage Expansion Card is designed to match the console’s internal SSD performance; Western Digital describes its WD_BLACK C50 as supporting Xbox Velocity Architecture. A USB external HDD or SSD is better treated as a library or transfer drive: it can store games and run supported older titles, but it is not a general substitute for an expansion card when playing optimized games.

Can you play Series X|S games from an external hard drive?
You can store most optimized Series X|S games on a USB drive, but storage does not guarantee that a game can launch from that drive. Seagate’s guidance says optimized games on USB need to be moved back to the internal storage or a Seagate Storage Expansion Card to play. Microsoft’s Xbox technology glossary likewise points to the internal SSD or an expansion card for optimized titles.

When a USB drive is the better option
A USB external HDD or SSD makes sense if you want more room for a broad library without paying specifically for direct-play storage for optimized games. It can also be a practical choice for supported Xbox One and earlier titles. Xbox hardware leader Jason Ronald described moving an existing compatible USB 3.1 drive from Xbox One to Series X|S as a way to get playing immediately; that statement concerns compatible games and does not mean every optimized Series X|S game launches from USB. Xbox Wire podcast transcript.
Seagate specifies USB 3.0 or newer and a minimum capacity of 128 GB in its Xbox Series X|S USB-drive guidance.

- Decide what you need to play from the added storage. If you want direct play for optimized Series X|S games, prioritize a compatible expansion card. If you mainly need space for supported older games or a library to keep and transfer, consider USB.
- Check USB requirements if you choose a drive. Seagate’s guidance calls for USB 3.0 or newer and at least 128 GB.
- Compare capacity, total price, and transfer convenience. A USB drive may suit bulk storage, but most optimized games on it require a move before play. A card is more convenient for those games; compare current prices and capacities where you live.
- Set the install location you want. Microsoft says the Seagate card can be selected as an install destination. Games can be played from it or moved or copied between storage locations. Xbox Wire setup and product details.
What the performance figures do—and do not—mean
Microsoft’s October 2021 Seagate-card announcement gives 2.4 GB/s raw I/O throughput for the custom internal SSD and says that is more than 40 times Xbox One’s throughput. This is a platform figure used to explain the storage design, not an independent benchmark comparing a retail expansion card with a USB HDD or SSD. Xbox Wire.
