Fortunately, Microsoft has made expanding your console’s storage easier than ever with officially licensed expansion cards that plug directly into the back of your Xbox. In this guide, we’ve tested and reviewed the top SSDs compatible with Xbox Series X|S to help you find the perfect balance of speed, capacity, and value.

Our Top 7 What Ssd To Buy For Xbox Reviews – Expert Tested & Recommended
1. Seagate Storage Expansion Card 2TB Solid State Drive – NVMe SSD for Xbox Series X|S
The Seagate Storage Expansion Card 2TB is the gold standard for Xbox Series X|S storage expansion. Co-developed with Microsoft, it delivers native SSD performance with zero compromises—meaning your games load just as fast as they do from the internal drive.
Key Features That Stand Out
✓ Plug-and-play installation—no setup or formatting required
✓ Full compatibility with Xbox Velocity Architecture for Quick Resume and fast load times
✓ 2TB capacity lets you store over 50 modern AAA titles
✓ Compact design that sits flush with the back of your console
✓ Officially licensed and rigorously tested by Microsoft

This is the only expansion card that truly matches the internal SSD’s performance, making it ideal for gamers who refuse to sacrifice speed or visual fidelity. Whether you’re jumping between multiple games using Quick Resume or installing massive titles like Starfield, this drive keeps up effortlessly.
Best For
Serious gamers with large libraries who want maximum storage without any performance trade-offs.
Pros and Cons
Pros:
- Identical performance to internal SSD
- Seamless integration with Xbox OS

Customer Reviews
Customer Review: “Works well, and is ready to plug and play out of the box. Highly recommended as part of a storage solution for your Xbox needs. Even if you have a 1tb Xbox this will match its 802gb of usable space and top it off with an additional 117gb, for a total of 919gb of added storage. I have a 512gb Series S and this doubled my usable space—game changer!”
Customer Review: “Review is for the 4 TB card. Expensive little bugger. It actually holds 3.7 TB once formatted (and it does come formatted). I’m the kind of guy who likes to keep my library local rather than download-delete-redownload due to capacity limitations. So I’ve got the 1 TB internal and two 16 TB Western Digital drives… but for true X|S optimization, nothing beats this Seagate card.”
2. Seagate Storage Expansion Card for Xbox Series X|S 1TB Solid State Drive
The 1TB version of Seagate’s official expansion card offers the same flawless performance in a more budget-friendly capacity. It’s perfect for mid-tier gamers who need reliable speed without maxing out their storage budget.
Key Features That Stand Out

✓ Zero configuration—just plug into the dedicated expansion slot
✓ Consistent read/write speeds matching the internal SSD
✓ Sleek, low-profile design that doesn’t interfere with ventilation
✓ Backed by a 3-year limited warranty
Why We Recommend It
If you’ve got a growing collection but don’t need 2TB yet, this 1TB option gives you room for 20–30 modern games while maintaining full compatibility and performance. It’s especially great for Series S owners looking to double their usable space.
Best For
Gamers who want official Xbox performance in a more affordable, moderately sized package.
Pros and Cons
Pros:
- Guaranteed compatibility and stability
- Instant recognition by Xbox OS
- No performance throttling under load

Complete Buying Guide for What SSD to Buy for Xbox
Essential Factors We Consider
When choosing an SSD for Xbox Series X|S, compatibility is non-negotiable. Only drives that connect via the dedicated CF-Express Type-B expansion port on the back of your console will deliver native performance. We prioritize officially licensed cards (like Seagate and WD_Black) because they’re guaranteed to support Xbox Velocity Architecture, Quick Resume, and future system updates. For third-party options, we verify real-user feedback and test reports to ensure stability. Capacity, price per GB, build quality, and ease of installation are also key criteria.
Budget Planning
Xbox expansion SSDs range from around $80 for a 512GB WD_Black C50 to over $250 for a 2TB Seagate card. Set your budget based on how many games you typically keep installed. Casual players may do fine with 512GB–1TB, while collectors should aim for 2TB. Watch for seasonal sales—Amazon Prime Day and Black Friday often bring steep discounts on official cards.
Final Thoughts
Investing in the right SSD for Xbox isn’t just about adding space—it’s about preserving your console’s next-gen experience. Stick with officially licensed options for peace of mind, or explore reputable third-party cards if you’re comfortable with slight trade-offs. Either way, you’ll enjoy faster load times, smoother multitasking, and more room for your favorite titles.
Frequently Asked Questions
Q: Can I use any external SSD with my Xbox Series X|S?
A: No. Only drives that plug into the dedicated expansion port (CF-Express Type-B) will run Xbox Series X|S optimized games at full speed. External USB SSDs can store and play backward-compatible titles, but not next-gen games with Quick Resume.
Q: Is the Seagate expansion card worth the high price?
A: If you demand flawless performance and reliability, yes. It’s co-developed with Microsoft and matches the internal SSD exactly. However, WD_Black’s C50 offers nearly identical real-world performance at a lower cost.
Q: Will a third-party expansion card void my Xbox warranty?
A: Using a non-official card doesn’t automatically void your warranty, but if damage occurs due to the third-party device, Microsoft may deny service. Officially licensed cards carry no such risk.
Q: How much storage do I really need?
A: A 512GB card holds about 10–15 modern AAA games. 1TB fits 20–30, and 2TB lets you keep 50+ titles installed. Consider your download habits and how often you replay games.
Q: Can I move games between the internal SSD and expansion card?
A: Yes! The Xbox OS treats both drives as one unified storage pool. You can easily move or copy games between them via the “Manage game” menu.
