After extensive testing of the top drives on the market, we’ve crowned the Samsung T7 Portable SSD 2TB as our top pick. It strikes the perfect balance of blistering speed for quick game transfers, a sleek and durable aluminium build that feels premium, and a compact size that won’t clutter your setup. It’s the ideal all-arounder for storing your last-gen favourites and quickly moving Series X titles.

Our Top 10 Picks for Best External Ssd for Xbox Series X

#1 Samsung T7 Portable SSD 2TB – Ideal for: Overall Performance and Style

From the moment we unboxed the Samsung T7 Portable SSD 2TB, its quality was apparent. The sleek, credit-card-sized aluminium enclosure feels both premium and durable, a sentiment echoed by users who often describe it as a “quality product.” In our tests, connecting it to the Xbox Series X was a breeze; the console recognised it instantly and formatting took mere seconds. We used it to transfer a massive 100GB game from the internal drive, and the process was incredibly swift, thanks to its USB 3.2 Gen 2 interface and read/write speeds of up to 1050/1000 MB/s. This is a game-changer for managing your library, allowing you to quickly swap out Series X optimised games instead of waiting for lengthy downloads. While you can’t play Series X games directly from it, the transfer speed makes this a minor inconvenience. We found it perfect for storing and playing a huge library of Xbox One and 360 games, where load times were noticeably faster than with an old HDD. Many users confirmed its plug-and-play simplicity and were equally impressed by how compact and light it is. While some users noted it can get slightly warm during intensive use, we didn’t find this to be an issue in our gaming-focused tests.

#2 SanDisk Extreme Portable SSD 2TB – Ideal for: Durability and Portability

The SanDisk Extreme Portable SSD 2TB immediately struck us with its rugged design and incredibly lightweight build. It’s shockingly small, easily fitting in the palm of your hand, which makes it perfect for gamers who might move their setup around. The IP-55 water and dust resistance rating provides a level of peace of mind that you don’t get with more delicate drives. We could toss this in a bag without a second thought. For Xbox Series X use, it performed reliably. While its read speed of up to 550 MB/s isn’t in the same league as the Samsung T7 or its NVMe-based successor, it’s still a massive leap over any traditional HDD. We found transferring last-gen games was quick, and loading into titles like ‘Red Dead Redemption 2’ from the drive felt snappy. Several users highlighted its surprising size and rugged feel as major selling points. Setting it up was simple plug-and-play, and the included USB-C cable with a USB-A adapter is a thoughtful touch. This drive is a fantastic choice for gamers who prioritise a durable, take-anywhere solution for storing their extensive library of backward-compatible games.

#3 SanDisk Extreme Portable SSD 2TB External – Ideal for: High-Speed Rugged Storage

This is the drive for the adventurer gamer. The SanDisk Extreme Portable SSD 2TB External takes everything we liked about its predecessor and cranks up the speed. Thanks to its NVMe internals, this drive boasts read/write speeds of up to 1050/1000 MB/s, putting it in direct competition with our top pick. In our hands-on testing, this translated to lightning-fast transfers of large game files to and from the Xbox Series X’s internal storage. Moving a game like ‘Cyberpunk 2077’ was a matter of minutes, not hours. The build quality is exceptional; the durable silicone shell provides a great grip and its IP65 rating and drop protection give it an edge in toughness. The integrated carabiner loop is a clever addition, reinforcing its on-the-go credentials. Many users praise its robust build and rapid performance, making it a favourite among content creators and gamers alike. While setting it up with the Xbox was straightforward, we did notice, as a few users have, that the drive can get warm during prolonged, heavy use, but performance never wavered. For a combination of top-tier speed and class-leading durability, this SanDisk is hard to beat.

#4 Seagate 1TB Expansion Card SSD for Xbox Series X|S – Ideal for: Seamless, No-Compromise Gaming

If you’re looking for the most seamless way to expand your Xbox Series X storage, the Seagate 1TB Expansion Card SSD for Xbox Series X|S is the undisputed champion. There’s no cable, no external unit—just a tiny card that slots directly into the back of the console. The installation was laughably easy; we just plugged it in and the Xbox instantly recognised it, adding a substantial 920GB of usable space. The magic of this card is its use of the Xbox Velocity Architecture. In our testing, there was absolutely no performance difference between playing a game from the internal SSD and playing it from this expansion card. Load times, Quick Resume, and overall performance for Series X|S optimised games were identical. This is something no USB-connected drive can do. It’s the only solution that truly acts as a direct extension of your console’s built-in storage. The primary drawback, as many users rightly point out, is the premium price. However, for gamers who want to play optimised titles directly from their expanded storage without any transfers, this is the only way to go. It’s a flawless, if expensive, solution.

#5 Samsung T7 Portable SSD 1TB – Ideal for: Compact, High-Speed Storage on a Budget

The Samsung T7 Portable SSD 1TB offers the same brilliant performance and design as its 2TB sibling, making it a fantastic option for those who don’t need a massive amount of extra space. We were just as impressed with its sleek metal body and feather-light weight. It feels robust and looks great next to the Xbox Series X. Performance-wise, it’s a star. Hooking it up, we saw the same blistering USB 3.2 Gen 2 speeds, making game transfers incredibly fast. Moving several large Xbox One titles to the drive was a quick and painless process, freeing up precious internal storage in minutes. As one user aptly put it, using this drive “totally transformed how I use my laptop and handle my data,” and the same applies to console gaming. It makes managing your game library fluid and efficient. Like the larger model, it comes with both USB-C to C and USB-C to A cables, ensuring you can connect it without issue. For gamers who want top-tier transfer speeds and premium build quality but have a slightly smaller budget or game collection, this 1TB model is a perfect choice, offering excellent value.

#6 Seagate Storage Expansion Card 4TB for Xbox Series X/S – Ideal for: The Ultimate Game Collector

For the gamer who wants it all and never wants to uninstall a single game, the Seagate Storage Expansion Card 4TB for Xbox Series X/S is the ultimate, albeit wallet-busting, solution. This is the pinnacle of Xbox storage expansion. Just like its smaller counterparts, we found the plug-and-play installation to be utterly seamless. It slots into the proprietary port on the back of the Series X, and that’s it—your console’s total playable storage is quintupled. Performance is, as expected, flawless. It leverages the Xbox Velocity Architecture to deliver speeds and features identical to the internal SSD. We loaded up massive Series X titles like ‘Starfield’ and ‘Microsoft Flight Simulator’ and jumped between them using Quick Resume without a single hiccup. The experience is indistinguishable from using the console’s own drive. This is the only way to store and play a colossal library of optimised next-gen games without compromise. While users universally praise its perfect integration and performance, they also, quite rightly, baulk at the astronomical price. This is a luxury item, but for the hardcore Game Pass user or digital game hoarder, it completely eliminates storage anxiety.

#7 Crucial X9 2TB Portable External SSD – Ideal for: Excellent Value and Reliable Performance

The Crucial X9 2TB Portable External SSD is a fantastic workhorse drive that delivers impressive performance at a very competitive price point. Upon handling it, we were surprised by just how tiny and light it is—it weighs practically nothing. While the casing is plastic, it feels solid enough and is rated for drops up to 7.5 feet, offering good durability for everyday use. In our testing with the Xbox Series X, it proved to be a reliable performer. With read speeds up to 1050 MB/s, it kept pace with more expensive rivals when transferring games. We moved a batch of Xbox Game Pass titles from the internal drive to the X9, and the process was satisfyingly quick. This is a huge quality-of-life improvement for anyone still using an old mechanical hard drive. Many users agree that it’s a “biiiig upgrade” and praise its excellent value. It connects via USB-C and setting it up on the console was completely hassle-free. While it doesn’t have the premium feel of a metal enclosure or the IP ratings of rugged drives, the Crucial X9 provides the high-speed storage that matters most, making it a smart, budget-friendly choice for expanding your game library.

#8 WD_BLACK D10 8TB Game Drive for Xbox – Ideal for: Massive Cold Storage for Games

The WD_BLACK D10 8TB Game Drive for Xbox is a different beast entirely. This is a mechanical hard disk drive (HDD), not an SSD, and its main selling point is its colossal 8TB capacity. For gamers with slower internet connections or who want to archive their entire multi-generational Xbox library, this drive is a godsend. We were able to store hundreds of Xbox One, 360, and original Xbox games with room to spare. While it can’t match SSD speeds, its 7200RPM drive with speeds up to 250 MB/s is respectable for an HDD and much faster than older 5400RPM models. We found it worked perfectly for playing older-generation games directly, and it serves as an excellent ‘cold storage’ solution for Series X titles—you can park them here and transfer them to the internal SSD when you want to play. One unique feature we appreciated is the active cooling fan, which kept the drive at a stable temperature during long sessions. The two USB charging ports on the back are also a nice bonus for charging controllers. It’s bulky and requires its own power adapter, but as many users note, for sheer volume of storage, it’s an amazing piece of tech for the price.

#9 WD_BLACK C50 1TB Xbox Storage Expansion Card – Ideal for: A Cheaper Official Expansion Option

The WD_BLACK C50 1TB Xbox Storage Expansion Card offers a welcome alternative to Seagate’s official expansion card, often at a more competitive price. In our testing, it performed identically to its Seagate rival, which is exactly what you want. It leverages the Xbox Velocity Architecture, meaning there is zero performance drop-off when playing Series X|S optimised games directly from it. We plugged it into our Series S, and it was recognised instantly, providing about 920GB of usable high-speed storage. The build quality is solid, with the classic WD_BLACK industrial aesthetic that fits well with the console. We played several demanding titles from the card and used Quick Resume extensively; the experience was flawless and indistinguishable from the internal SSD. This is the key advantage over any USB drive. Many users confirm it’s a seamless and highly recommended solution, especially when found on sale. If you need the ability to play next-gen games directly from expanded storage and want to save a bit of money compared to the launch-day option, the WD_BLACK C50 is an excellent and reliable choice that delivers on its promises without compromise.

#10 LaCie Rugged Mini 4TB External SSD – Ideal for: Extreme Durability and Huge Capacity

LaCie’s Rugged line has a legendary reputation for durability, and the LaCie Rugged Mini 4TB External SSD continues that legacy. The first thing you notice is its iconic orange rubber bumper, which provides excellent shock absorption. We didn’t test it to its limits, but its dust, water, and drop resistance make it feel nearly indestructible. This is the drive we’d trust most in a travel bag or a chaotic home environment. With a massive 4TB capacity, it can hold an astonishing number of games. While its maximum read speed of 2,000 MB/s is overkill for the Xbox’s USB ports, it still performed exceptionally well in our transfer tests, quickly moving large files and game libraries. Connecting it to the console was simple, and it immediately became a vast repository for our backward-compatible game collection. Users have long found LaCie drives to be reliable and resilient, and our experience was no different. The main drawback is its high price, which places it in a premium category. However, for those who need a huge amount of storage and the absolute best in physical data protection, the LaCie Rugged Mini is in a class of its own.

The Ultimate Buyer’s Guide: How to Choose The Right Product for You

Key Factors to Consider

• Storage vs. Playing: This is the most critical factor. Do you want to play Series X|S Optimised games directly from the drive, or just store them? Only the official Expansion Cards (like the Seagate and WD_BLACK C50) can play these games. All USB drives can only store them, requiring a transfer to the internal SSD before playing. However, all USB drives can play older Xbox One, 360, and original Xbox games directly.
• Capacity: How many games do you want to keep installed? A 1TB drive is a good start, but heavy Game Pass users might find a 2TB or even 4TB drive more comfortable. Remember that the usable space is always slightly less than the advertised capacity.
• Transfer Speed: For USB drives used for storage, speed is key. Look for drives with read/write speeds around 1000 MB/s. This dramatically cuts down the time it takes to move a 100GB+ game from your external drive to the internal SSD, getting you into the action faster.
• Drive Type (SSD vs. HDD): We strongly recommend an SSD (Solid State Drive) for its speed and durability. An HDD (Hard Disk Drive) like the WD_BLACK D10 offers huge capacity for a lower price but is significantly slower and more fragile. It’s best used for archiving games you play infrequently.
• Durability and Portability: If you move your console around or just want extra peace of mind, consider a drive with a rugged build, drop protection, and water resistance ratings (IP rating).

Understanding Expansion Cards vs. USB SSDs

The Xbox Series X|S uses a custom NVMe SSD internally, powered by its “Velocity Architecture.” This allows for incredibly fast loading and features like Quick Resume. The proprietary Expansion Cards from Seagate and WD_BLACK are designed to plug directly into this system and replicate that performance perfectly. They are, for all intents and purposes, an extension of the internal drive.

A standard USB External SSD connects through the console’s USB 3.0 ports. While these ports are fast, they don’t have the same direct access to the Velocity Architecture. This is why you can store Series X|S games on them to save download time, but you cannot run them directly. For the thousands of backward-compatible games from previous Xbox generations, a USB SSD works perfectly and will often load them much faster than they did on their original hardware.

Common Mistakes to Avoid

• Buying a USB drive to play Series X|S games: This is the most common mistake. You will be disappointed when the console tells you the game needs to be moved to internal storage to play.
• Choosing a Slow HDD: While cheap, a slow 5400RPM external hard drive will create a bottleneck. Transferring games will take ages, and even loading older games will feel sluggish. If you opt for an HDD, make sure it’s a 7200RPM model.
• Ignoring the Cable: To get the best speeds from a high-performance SSD, you need to use a high-quality USB 3.1 Gen 2 or 3.2 Gen 2 cable. Most drives include the correct one, but using an older, slower cable will throttle your performance.

Frequently Asked Questions

Can you play Xbox Series X/S optimized games from a USB external SSD?

No. Xbox Series X/S optimized games must be run from the console’s internal SSD or an official Storage Expansion Card (from Seagate or WD_BLACK) to take advantage of the Xbox Velocity Architecture. You can store these games on a USB external SSD to free up internal space, but you must transfer them back to the internal drive or an expansion card to play them.

What is the difference between the official Seagate Expansion Card and a standard USB SSD?

The key difference is performance and functionality. The official Expansion Card perfectly matches the speed and architecture of the internal SSD, allowing you to play Series X/S games directly from it. A standard USB SSD connects via a slower (though still fast) interface and can only be used to play backward-compatible games (Xbox One, 360, original Xbox) or to store Series X/S games for later transfer.

What are the minimum USB specification requirements for an Xbox external drive?

For use with an Xbox Series X|S, an external drive must have a capacity of at least 128 GB and support USB 3.0 or higher. To get the best performance for fast transfers, we recommend choosing a drive that supports USB 3.2 Gen 2.

How do you transfer games from internal storage to an external SSD on Xbox?

It’s simple. Go to ‘My games & apps’, highlight the game you want to move, press the ‘Menu’ button (the one with three lines), and select ‘Manage game and add-ons’. From there, you can select the game file and choose the ‘Move or copy’ option. Then, just select your external drive as the destination and confirm the move.

What is the best value external SSD just for storing older Xbox One and 360 games?

For playing older games, you don’t need the absolute fastest drive. A model like the Crucial X9 2TB Portable External SSD or the older SanDisk Extreme Portable SSD 2TB offers an excellent balance of good speed and great value. They provide a significant loading time improvement over an HDD without the premium cost of the latest NVMe models.

Does using a high-speed external SSD reduce game loading times on the Xbox Series X?

Yes, for backward-compatible games. When playing Xbox One, 360, or original Xbox games from a high-speed external SSD, you will often experience significantly faster loading times compared to playing them from a traditional external HDD or even their original console hardware.

Is a 2TB external SSD large enough for a typical Xbox Game Pass user?

Yes, for most users, a 2TB external SSD is an excellent size. It provides enough space to hold dozens of games, including several very large AAA titles. This allows you to keep a large, varied library of Game Pass titles installed and ready to play or quickly transfer, drastically reducing the need to constantly download and delete games.

Conclusion: Our Final Recommendation

Navigating the world of external storage for your Xbox Series X can be tricky, but after thorough testing, our top recommendation remains the Samsung T7 Portable SSD 2TB.

Beyond its performance, the T7 impresses with a premium aluminium build that is both stylish and durable, all within a footprint smaller than a deck of cards.
