Xbox Series X and Series S introduce significant changes to system storage, adopting custom solid-state drives (SSDs) under the hood. Microsoft has positioned this high-speed storage as fundamental to next-generation gaming, helping deliver shorter load times with support for complex game worlds. This SSD requirement guarantees the best from the latest Xbox consoles but can make storage expansions a little more complicated. You now have a few options when adding space to your Xbox Series X and Xbox Series S versus Xbox One, and it's essential to understand which works best for you.
Expanding Xbox Series X, Series S storage: The basics
Xbox Series X and Xbox Series S pack the same SSD storage, bringing up to 40 times speed increases over older Xbox One consoles. Microsoft opted for a custom solution based on NVMe SSD technologies, delivering best-in-class read and write speeds, albeit costly compared to the slower hard drives from the Xbox One era.
The Xbox Series X ships with a 1TB internal SSD drive, while the Xbox Series S features a reduced 512GB capacity out of the box. In reality, Xbox Series X has just 802GB of space usable for games, with Xbox Series S offering just 364GB. With new releases from franchises like Call of Duty, Halo, and NBA 2K now surpassing 100GB, it's easier than ever to outgrow the included storage.
When your games library eventually fills the internal drive, Microsoft provides two primary routes to increase your available storage on Xbox Series X and Series S. The best solution is the Seagate Storage Expansion Card for Xbox Series X|S, a compact memory card-style SSD developed in collaboration with Seagate, mimicking the internal SSD with identical performance. It also supports USB external hard drives like Xbox One consoles, albeit with major limitations.
In brief, the growing list of Xbox Series X and Series S Optimized games need high-speed storage, and only Microsoft's custom SSDs can deliver. Beyond the internal SSD included with Xbox Series X and Xbox Series S, the official Xbox Storage Expansion Card is the only seamless upgrade.
While USB hard drives work fine, they only store those games, and you will need to transfer them to the SSD to play. However, backward-compatible titles, including Xbox One, Xbox 360, and original Xbox games, work fine on USB drives. Here's a handy breakdown of how USB drives compare to the SSD expansion card.
|Internal SSD||Seagate Expansion Card||USB external drive|
|Xbox Series X/S games||✓||✓||Storage only|
|Xbox One games (upgraded)||✓||✓||Storage only|
|Xbox One games (not upgraded)||✓||✓||✓|
|Xbox 360 games||✓||✓||✓|
|Original Xbox games||✓||✓||✓|
The challenges around storage space only grow for Xbox Series X and Series S, with top titles larger than ever. The latest blockbusters demand more storage, with the added increased capabilities of the latest consoles unlikely to reverse that trend. While Microsoft states that Xbox Series S titles should sometimes clock in smaller than Xbox Series X, storage is far from plentiful on either device.
Xbox Series X, Series S Seagate Expansion Card
With Xbox Series X and Series S focused on delivering next-gen experiences, games designed for the consoles require the full bandwidth of their custom SSD technologies. Traditional USB external hard drives don't hit the mark, which saw Microsoft and Seagate cook up a custom "Storage Expansion Card." In short, it's a proprietary, high-speed SSD that's guaranteed to meet the standards for Xbox Series X and Xbox Series S.
The Xbox Expansion Card makes it simple, with three sizes available in 2021. Seagate Storage Expansion Cards are available in 512GB, 1TB, and 2TB flavors, with pricing proportional to their respective capacities. While Microsoft has also discussed storage from other manufacturers, the ongoing exclusivity period with Seagate means we're yet to see those materialize.
While undeniably a premium device, it's a result of the bleeding-edge hardware inside, falling in line with our previous predictions given the average pricing for current PCIe 4.0 SSDs. The card guarantees the best in internal and external storage, albeit with a higher cost than slower USB drives.

The Seagate Storage Expansion Card for Xbox Series X|S aims to deliver the best possible gaming experience, exactly matching Microsoft's baked-in solution. The cards deliver best-in-class technology without compromising convenience and you'll need to pay for the luxury.
The Xbox Storage Expansion Card, as expected, costs more than your everyday hard drive. Pricing starts at $139.99 for entry-level 512GB model, while the 1TB and 2TB versions cost $219.99 and $399.99, respectively.
Seagate Storage Expansion Card for Xbox Series X|S (512 GB)
Seagate's entry-level Xbox Storage Expansion over doubles available space for Xbox Series S consoles, while adding over 50% more room to Microsoft's Xbox Series X. This budget-friendly add-on means space for a few more games.
Seagate Storage Expansion Card for Xbox Series X|S (1 TB)
This 1TB expansion launched in tandem with Xbox Series X, exactly matching the internal hard drive, or tripling what's available for Xbox Series S. The ideal middle ground for most, accommodating larger game collections or Xbox Game Pass aficionados.
Seagate Storage Expansion Card for Xbox Series X|S (2 TB)
The latest and greatest Expansion Card clocks in at 2TB, and for many, provides ample overhead for dozens of extra titles. While that high price might be hard to justify, it's a one-stop storage companion primed for the next decade of Xbox gaming.
How to use the Xbox Seagate SSD Expansion Card
The Seagate Storage Expansion Card connects to Xbox Series X and Series S via a dedicated, proprietary connector on the console's rear. The rectangular port sits adjacent to the HDMI output on both consoles, labeled with "STORAGE EXPANSION." They come in only slightly larger than your average USB thumb drive, with a sliding plastic cover for safekeeping. Upon removing the included cover, the SSD slides into the port, slightly protruding from the back I/O panel.
Microsoft also allows external SSD cards to be inserted with the console turned on, enabling those with multiple expansion cards to hot-swap on the fly. When inserted, the Xbox Series X or Xbox Series S will automatically recognize and configure your external storage.
- Remove the protective sleeve included with the Xbox Storage Expansion Card.
- Insert the Expansion Card into the Storage Expansion port.
- Firmly press the Expansion Card until it emits a distinct click. Your Xbox console will automatically detect and configure the Xbox Storage Expansion Card, coupled with an on-screen notification.
Once configured to work with your Xbox Series X or Xbox Series S console, the Xbox Storage Expansion Card will add its respective capacity to your pool of available Xbox storage. However, a small fraction of storage will be reserved for the system. For example, the 1TB Storage Expansion Card actually adds 920GB, with around 100GB locked down out of the box. Following set-up, you can copy, move, and install content between the internal SSD and the external Storage Expansion Card.
Does Xbox Series X, Series S support USB external hard drives?
Microsoft supports almost all Xbox One accessories with Xbox Series X and Series S, extending to the existing storage ecosystem. That guarantees partial compatibility for external hard drives from the Xbox One era via USB connectivity. It makes them an ideal, budget-friendly alternative to the official Seagate Storage Expansion Card, especially when offloading titles from the internal drive.
However, USB drives don't match Microsoft's custom SSD speed, imposing significant limitations on their capabilities. Xbox One, Xbox 360, and original Xbox titles all run on an external USB hard drive with Xbox Series X and Series S. And provided previous-generation software doesn't receive Xbox Series-geared upgrades, it also runs on USB storage.
But Xbox Series X and Series S titles won't run on external hard drives due to slow transfer speeds, failing to meet next-generation demands. An internal SSD or an external expansion card is required for upcoming releases or older games updated for Xbox Series X or Series S.
But with the high price of the SSD expansion card, it's worth stressing that all Xbox Series X and Series S titles can be offloaded to an external USB hard drive. While some titles may not be playable from the slower storage, it's still possible to shift data between an SSD where your games can be playable and a USB for storage. Your USB hard drive's transfer speeds will determine how fast they move back and forth, but it's a useful way to cycle games from the internal SSD without investing in the $220 expansion card.
Best Xbox Series X, Series S external hard drives
If the SSD Expansion Card isn't for you, a vibrant ecosystem of USB-connected hard drives will meet demands for Xbox One, Xbox 360, and original Xbox titles. These storage solutions all function with Xbox Series X and Series S today, multiplying your console's capacity, with plug-and-play access also guaranteed for older Xbox One consoles.
The best Xbox Series X hard drives start as cheap as a video game, with Toshiba offering reliable storage within performance demands below $50. That 1TB expansion can over triple your room across some consoles like Xbox Series S.

While SSDs are incredibly costly in these sizes, slower hard drives remain affordable right now.
Opting for an SSD will boost your read and write speeds over a traditional hard drive, cutting load times across your favorite titles on Xbox One consoles. And while even the best external SSDs for Xbox Series X and Series S don't meet the demanded speed for Xbox Series X|S Optimized titles, that boost still comes in handy for backward compatibility or fast transfers to your internal SSD.

Samsung's T7 500GB external drive packs top-tier speed below $100. You're getting an over 50% boost in capacity with Xbox Series X while over doubling Xbox Series S. That speed won't match what's inside either console, but it's still a vast improvement over other USB drives. Encased in a shock-resistant metal finish; it fits stealthily beside any console.
How to use a USB external hard drive with Xbox Series X, Series S
Most modern external hard drives work on Xbox Series X and Series S consoles, expanding your capacity for games, with speedier load times also obtainable via compatible SSDs. You'll need a USB 3.0 external drive to meet the requirements, ensuring high data transfer rates to run backward-compatible games over a USB connection. Compatible drives must also have at least 256GB of storage, although we recommend shopping for at least 1TB for future peace of mind. Don't forget that the best Xbox One hard drives and SSDs are also compatible with new Xbox consoles if you've recently made the upgrade.
The Xbox Series X and Series S feature USB-A ports, making it important to check whether an external hard drive uses the correct connector to hook up to the console. That's especially important with modern SSDs, more commonly using USB-C connectors to achieve the highest possible transfer speeds. The two consoles feature twin rear-facing USB-A ports, ideal for hiding external hard drives while freeing up the front port.
You'll also need to permit your console to format the drive, losing all data currently stored onboard. It's crucial to back up ANY stored files to avoid losing existing documents and data. Your Xbox console will automatically detect external storage when connecting a USB external drive, with on-screen prompts to ease the setup process.
This external hard drive can be used to store Xbox Series X|S games, although you'll need to transfer them to the internal SSD, or an official Xbox Storage Expansion Card, when it's time to play. However, older Xbox One, Xbox 360, and original Xbox games still work as normal with these USB drives.
A caveat: Play Xbox Series X|S games via USB drives
Titles developed with upgrades for Xbox Series X and Xbox Series S need Microsoft-approved SSD storage, but diving into the technicalities, that's not always the case. The way Xbox Series X|S Optimized games are developed means that some don't require the full benefits of SSD storage and operate via USB-based storage devices. Under the hood, these titles essentially run as standard Xbox One games, only with some enhancements when booted on Xbox Series X and Xbox Series S systems.
In reality, that means some Xbox Series X|S Optimized titles can be on USB hard drives, even if not formally intended. While entirely functional, this may impact performance or load times when running these titles on your system. You can identify these games through the following steps.
- Open My games & apps on your Xbox console.
- Navigate to your chosen game.
- Press the Menu button.
- Select Manage game and add-ons.
- Select the File info tile.

Seagate Expansion Card vs. USB: Which is for you?
When your Xbox Series X or Xbox Series S runs low on storage, your decision to expand primarily hinges on whether to invest in the official Seagate Storage Expansion Card for Xbox. With fast storage fundamental to titles designed for the next generation, this external SSD offers a seamless solution at a high price. The cost may deter some but reflects the reality of the hardware, pushing the best from either console.
While Microsoft first launched its Storage Expansion Card with just one 1TB model from Seagate, we're now seeing additional capacities hitting the market, spanning a variety of price points. Pricing now starts at $140 for the entry-level 512GB model, while those with larger game collections can invest considerably more with 1TB and 2TB variants.
USB external drives may yield more gigabytes for your dollar, but the functionality posed by official Xbox Expansion Cards helps justify the cost. It might be a significant investment, but with years of Xbox Series X and Xbox Series S games ahead, it's a solid companion for the latest console generation. It delivers the most seamless extension of the console's internal SSD, avoiding the pain of shuttling games between drives on the regular.
Investing in a USB external hard drive may be more appropriate when looking for an affordable alternative, especially in the short term. Connecting USB devices is an easy way to store your games, even if the limitations mean you can't play without moving them to your internal SSD. It saves redownloading titles, provided you're happy to cycle them back and forth.
