Hey there, Xbox Series S gamers! Are you constantly running into that “storage full” message? You’re not alone. The Xbox Series S is an incredible little console, but its 512GB internal SSD fills up surprisingly fast, especially with today’s massive game files. To keep your gaming marathon going without constantly uninstalling and reinstalling games, an external SSD is practically a must-have.
But which one should you choose? Many folks are searching for the Sabrent best external SSD for Xbox Series S, wondering if Sabrent offers the ultimate solution. While Sabrent makes fantastic storage, there’s a crucial distinction when it comes to playing optimized Xbox Series X|S games. In this article, we’re going to dive deep into the top 5 external SSD options, including a look at Sabrent’s offering, to help you find the perfect storage upgrade for your console. We’ll break down what makes each one stand out, their pros and cons, and real-world user impressions, so you can make an informed decision and get back to gaming!
Understanding Xbox Series S Storage Needs
Before we jump into the reviews, let’s quickly clarify how external storage works with the Xbox Series S. For games specifically optimized for Series X|S (those with the X|S logo), you must run them from either the internal SSD or an officially licensed Xbox Storage Expansion Card. These expansion cards plug directly into a dedicated slot on the back of your console and leverage the Xbox Velocity Architecture for blazing-fast load times and seamless next-gen performance.
Regular external SSDs (like many from Sabrent) are excellent for storing older Xbox One, Xbox 360, and original Xbox games, or for archiving Series X|S games. You can play older titles directly from them, but to play Series X|S optimized games stored on a regular external SSD, you’ll need to transfer them back to your console’s internal drive or an expansion card first. This is a critical point when considering the “best external SSD for Xbox Series S.”
Now, let’s explore our top picks!

Conclusion: Finding Your Best Xbox Series S External SSD
So, what’s the Sabrent best external SSD for Xbox Series S? If your main goal is to seamlessly play Xbox Series X|S optimized games directly from external storage, then an officially licensed expansion card from Seagate or WD_Black is undeniably the best choice. These cards leverage the Xbox Velocity Architecture to deliver identical performance to your console’s internal SSD.
However, if you have a massive library of older Xbox One, Xbox 360, or original Xbox games, or you want a super-fast external drive primarily for PC/Mac use that can also store Series X|S games for archival purposes (requiring transfer back to internal storage to play), then a high-performance portable SSD like the Sabrent Rocket XTRM Plus could be an excellent, versatile option.
Ultimately, the “best” SSD for your Xbox Series S depends on your specific gaming habits, your budget, and whether you prioritize playing next-gen titles directly from external storage or simply need more space for older games and archiving. No matter your choice, expanding your storage will definitely enhance your Xbox Series S gaming experience!
FAQ Section
Q1: Can I use any external SSD with my Xbox Series S?
A1: Yes, you can use almost any external SSD with your Xbox Series S. However, there’s a crucial distinction: only officially licensed Storage Expansion Cards (like those from Seagate and WD_Black) can run Xbox Series X|S optimized games directly. Standard external SSDs can store these games, but you’ll need to transfer them to the console’s internal SSD or an expansion card to play them. They work perfectly for playing older Xbox One, Xbox 360, and original Xbox games directly.
Q2: What’s the difference between an external SSD and an expansion card for Xbox Series S?
A2: An external SSD connects via a USB port and is typically a universal storage device. It’s great for older games and archiving. An expansion card is a proprietary device that plugs into a dedicated expansion slot on the back of your Xbox Series S. It’s specifically designed to integrate with the Xbox Velocity Architecture, offering identical performance to the internal SSD and allowing direct play of all Xbox Series X|S optimized games.
Q3: Why are Xbox Series S expansion cards so expensive?
A3: The higher cost of expansion cards is due to their proprietary technology and specific design requirements. They need to perfectly match the speed and performance of the console’s internal NVMe SSD and integrate with the Xbox Velocity Architecture. This ensures seamless performance for next-gen games, which off-the-shelf external SSDs cannot provide.
Q4: How much storage do I really need for my Xbox Series S?
A4: It really depends on your gaming habits. The Xbox Series S has about 364GB of usable space. If you play a lot of large AAA titles, even 1TB can fill up quickly. Many find 1TB to 2TB to be a good balance. If you’re a serious collector or want to download every game that piques your interest, 4TB might be worth the investment.
Q5: Can I play Xbox Series S/X optimized games directly from a regular external SSD?
A5: No, unfortunately, you cannot. Xbox Series X|S optimized games require the ultra-fast data transfer speeds and specific architecture provided by the console’s internal SSD or an officially licensed expansion card. A regular external SSD can store these games, but you’ll need to move them to the internal drive or an expansion card to actually play them.
Q6: Is it worth getting an expansion card for my Xbox Series S?
A6: If you frequently play Xbox Series X|S optimized games and find yourself constantly deleting and re-downloading titles, then yes, an expansion card is absolutely worth it. It provides a truly seamless, “no-compromise” experience, allowing you to build a larger library of next-gen games ready to play instantly.
Q7: Does using an external SSD or expansion card affect Quick Resume?
A7: When using an official Storage Expansion Card, Quick Resume works exactly as it does with games on the internal SSD. You can switch between multiple titles in seconds, regardless of whether they are on the internal drive or the expansion card. For older Xbox One games stored on a regular external SSD, Quick Resume also typically works well.
