Modern gaming motherboards make it easy to install M.2 SSDs and instantly gain high-performance storage. However, Microsoft's restrictions severely limit Xbox Series X upgrade options. Only a handful of approved expansion cards permit gamers to install and boot the most recent titles. Otherwise, players must first transfer archived games from an external SSD or hard drive to internal storage.
Best PCIe 5.0 SSDs in 2024
Ready to upgrade your NVME M2 storage? These top-tier PCIe 5.0 SSDs are the best you can find!
With Microsoft recently announcing a new Xbox Series X Digital console, there will undoubtedly be demand for expanding its 1 TB capacity. Even owners of current Xbox consoles are searching for solutions, as games with cutting-edge graphics eat away at internal drives. When looking for speedy and spacious storage, buyers should first decide whether loading games directly from an SSD is a requirement. External USB drives aren't as convenient, but they can boot Xbox One games and are considerably cheaper than Microsoft-approved products. Other critical factors include the type of storage technology, which affects both read and write rates and portability.
Game ZXC's Best SSDs and Expandable Storage for the Xbox Series X
Seagate Storage Expansion Card for Xbox Series X|S 1TB
The Seagate Storage Expansion Card for Xbox Series X|S is a proprietary add-on storage slot. It clips on the back of both current-generation consoles using a connector that resembles a CF Express card but supports PCI-E 4.0 Speeds for data transfer to the Xbox.

- Fairly compact
- Faster than USB-connected drives
- Not quite as speedy as internal storage in some tests
- More expensive than higher capacity storage options
The Seagate Storage Expansion Card is one of the most popular ways to expand the storage of Xbox Series X consoles. This expansion card slots into the back of consoles as one of only a few solutions that can play Series X-optimized titles directly. Within minutes, gamers can expand their internal storage by up to 2 TB, depending on the version purchased. Although it's pricey compared to USB alternatives, the Seagate Storage Expansion Card appeals to buyers looking for a no-compromise Xbox Series X storage solution.
Seagate's expansion works so seamlessly in the Series X because of its support for Xbox Velocity Architecture. Essentially, the technology both shrinks the size of the files installed games use and employs asset streaming to reduce load times. Consequently, without first transferring large games from external drives, the Seagate drive boots games nearly as quickly as the console's internal storage.
As NVMe storage, gamers can expect this drive's performance to be on par with faster gaming SSDs. That said, in some tests, load times for certain games were slightly faster with the Series X's native drive. Also, there is adequate shielding, but if durability when traveling is the priority, it likely won't outlast a reinforced external SSD like the Samsung T7 Shield.
With the release of the Xbox Series X Digital looming, stock levels will likely run thin with the Seagate Storage Expansion Card. Until Microsoft supports a wider range of more affordable drives, it remains the preferred way to accommodate more game installs and downloads.
WD_BLACK C50 Storage Expansion Card for Xbox
The WD_BLACK C50 Storage Expansion Card for Xbox presents excellent value for those looking for an SSD that can run games optimized for the Xbox Series X|S. It's slightly more affordable than the Seagate expansion card and comes in a 512GB capacity option.
- Storage capacity
- 1TB
- Hardware Interface
- Proprietary
- Compatible Devices
- Xbox Series S, Xbox Series X
- Brand
- Western Digital
- Warranty
- 5 years
- Officially licensed by Microsoft
- Durable exterior
- Often available for less than its Seagate rival
- Speedy and silent
- No 2 TB version available
- Marginally longer than Seagate Expansion Card
The arrival of the WD_Black C50 in 2023 was a welcome relief to Xbox gamers desperate for more storage. Previously, the Seagate Storage Expansion Card was the only way to expand the capacity of Xbox Series X and S consoles without transferring from USB drives. With added competition usually comes lower prices, and especially in its 512 GB variety, the WD_Black C50 is the most affordable answer to storage space dilemmas.
There are few differences between the C50 and Seagate cards in terms of architecture and performance. Both are compatible with the expansion slot on the rear of Xbox consoles and play games directly with minimal hassles. However, there are huge visual contrasts, with the C50 having a black exterior with ridges. The WD card is a bit longer, but it's also chunkier and seems less prone to drops from damage. Gamers will also appreciate the open slot towards its base, making it easier to grab securely.
The Best Budget Gaming Controllers in 2024
Looking for gaming controllers that deliver great value for a steal? Then check out Game ZXC's top picks!
The WD_Black C50 embraces Xbox Velocity Architecture and supports Microsoft's Quick Resume. As a result, gamers can hop between titles without repeatedly enduring a lengthy booting process. The C50 may not match the Xbox's internal storage speed, but it's doubtful that most gamers will notice a difference.
For buyers needing a modest amount of extra storage, the C50 is the best Xbox Series X SSD. At 512 GB, the drive also won't break the bank after already investing in a gaming TV or other accessories vital to a setup. The only disappointment for buyers with more demanding needs is that there is no 2 TB version.
Seagate Game Drive Hub for Xbox 8TB
The Seagate Game Drive Hub is one of the most cost-efficient ways to build a large collection of Xbox titles. Using a USB 3.2 Gen 1 connection to the console, gamers can play Xbox One titles directly from the Game Drive Hub. After a high-speed transfer from the external drive, the latest games become ready to play on the Xbox Series X/S. The Game Drive Hub perfectly matches the look of the Xbox Series X, complete with LED lighting.
- Storage Capacity
- 8 TB
- Compatible Devices
- Xbox One, Xbox Series X/S, PC
- Dimensions
- 8.11in/206mm x 1.937in/49.2mm x 5.039in/128mm
- Brand
- Seagate
- More storage for a lower cost compared to SSDs
- Looks like an Xbox accessory
- USB-C and USB-A ports on front to charge accessories
- LED lighting customizable on PCs
- Requires external power adapter
- Slower than SSDs
SSDs have become the ideal storage components for desktops, laptops, and gaming consoles. However, 3.5-inch internal mechanical and external USB hard drives remain more cost-effective storage methods. The Seagate Game Drive Hub is a USB 3.2 Gen 1 hard drive that isn't blazingly fast but generously sized and a surprisingly versatile Xbox accessory.
Unlike the Seagate Storage Expansion Card, the Game Drive Hub connects to a USB port on the Xbox Series X. Also, it can only be used to play Xbox One-era games, while users must first transfer titles over to Series X or S internal storage to play them. Adding external storage is still relatively easy, thanks to guiding prompts on the Xbox dashboard. Buyers do need to keep in mind that the Game Drive Hub requires an external power adapter.
What the Game Drive Hub lacks in read and write speeds, it makes up for in convenience and an attractive design. With some USB hub capabilities, Seagate's drive has USB-C and USB-A ports on its front panel, which can recharge Xbox controllers and other peripherals. Another less functional aspect of the Game Drive Hub is its stripe of LED lighting. The effects are green by default, but Seagate provides PC software that can change their color. If gamers would rather use the drive for PC storage, the drive can even sync with Razer RGB keyboards and mice through the Synapse app.
Ultimately, the Game Drive Hub is the best Xbox Series X storage option to fit in with the aesthetic of a console setup. If looking for the most storage per dollar, it's also hard to argue against the value the 8 TB version offers.
Samsung T7 Shield
Compact and durable, the Samsung T7 Shield is perfect if you want something to use while on the go. Its tough and water-resistant exterior can keep your games and media files safe while at home or out and about.
- Storage capacity
- 1TB, 2TB, 4TB
- Compatible Devices
- Playstation, Xbox, PC, Mac
- Brand
- Samsung
- Hardware Interface
- USB 3.2 Gen.2
- Transfer rate
- 1,050MB/s
- Warranty
- 3 years
- Withstands harshest weather conditions
- Consistent transfer speeds
- Available in several different colors
- Compact form factor
- Not as fast as some competing external SSDs
- Extra shielding adds to its weight
Xbox gamers who travel back and forth to college or live in different locations during the year find durable external SSDs advantageous. The Samsung T7 Shield's thick rubberized shell can withstand rain, wind, and extreme heat. Inside the casing is an NVMe SSD that connects to the Series X with USB 3.2 Gen 2, exceeding the console's specs.
Despite the reinforced exterior of the T7 Shield, it remains reasonably compact, particularly compared to traditional USB hard drives like the Seagate Game Drive Hub. At the same time, it adds to its weight, which owners may notice when hauling the drive in backpacks. Still, the T7 can survive drops and almost any calamity besides being completely submerged in water. This SSD also keeps its temperature in check, so Xbox gamers won't have to worry about overheating even after transferring an entire drive filled with titles.
The T7 Shield doesn't require a power adapter and connects to any of three USB 3.0 ports on consoles. Gamers may find that some competing drives boast superior speeds, but the T7 exhibits consistent write rates without throttling. The T7 Shield also thrives with PCs and Macs, where users can benefit from powerful software and hardware encryption. Having a choice of Black, Blue, and Beige enables the SSD to blend in with Series X consoles, even those with custom skins.
The Best Xbox Series X Skins for 2024
It's easy to give the Xbox a makeover, but which Xbox Series X skins are the best options for players?
Not every console can enjoy a permanent home on the same TV stand year-round. The resilient Samsung T7 Shield is the best Xbox Series X storage solution for buyers with more fluid gaming setups.
Avolusion HDDGear Pro X External Gaming Hard Drive
Console gamers looking for the most storage space possible at an affordable asking price should look no further than the Avolusion HDDGear Pro X. This external USB 3.0 hard drive is available in sizes up to 12 TB and offers versions pre-formatted for Xbox and PlayStation file systems. The HDDGear Pro X also looks like a sleek gaming accessory while being heavily shielded to keep it quiet during long file transfers. With an intelligent, fanless design, the external drive stays cool while handling the heaviest workloads.
- Storage Capacity
- 2TB, 3TB, 4TB, 6TB, 8TB, 10TB, 12TB
- Compatible Devices
- Xbox Series X/S, PC
- Dimensions
- 8"(L) x 5"(W) x 1.6"(H)
- Brand
- Avolusion
- Very affordable for massive amount of storage
- Pre-formatted with Xbox file system
- Stays quiet and cool
- Modern look fits in with gaming setups
- Some reliability concerns
- Large form factor
SSDs have obvious appeal for speed and efficiency but are less practical for demanding storage needs. The Avolusion HDDGear Pro X can stand vertically or horizontally on or near the Xbox Series X without looking out of place. A heavy-duty exterior keeps the normally noisy 7200 RPM hard drive inside reasonably quiet.
With some LED lighting to attract attention, the HDDGear Pro X is clearly geared toward console gamers, and it's pre-formatted for the Xbox file system. Even though the formatting process is usually painless, this alleviates some of the anxiety novices face when dealing with new drives. Unlike the PS5, the Xbox Series X welcomes external hard drives larger than 8 TBs, so buyers can connect a 12 TB HDDGear Pro X USB 3.0 cable to an available port.
Buyers will have to devote considerable space to the HDDGear Pro X but are rewarded with near-silent operation. It's also well-ventilated, negating the need for any annoying fans. As with all storage of this type, gamers won't be able to launch Series X titles directly from the HDDGear Pro X, but they can build a virtually limitless archive of games and files.
It's always somewhat risky to purchase external storage without knowing exactly what hard drive is inside. Buyers who have opened their cases have found various branded drives with different performance and reliability ratings. Nevertheless, the HDDGear Pro X is not new to the market and comes with a 2-year limited warranty if disaster strikes.
Massive, attractive, and quiet, the Avolusion HDDGear Pro X is a great alternative to smaller and pricier Xbox Series X SSD options.
Buffalo SSD-PUT Portable SSD Stick
The Buffalo Portable SSD Stick is one of the most compact high-performance storage devices on the planet. Combining the portability of USB flash drives with the speed of an SSD, the SSD-PUT connects to PCs, consoles, and other devices with a USB 3.2 connection. Thanks to a retractable design, buyers can easily travel with this Buffalo SSD while experiencing up to 600 MB/s speeds. The SSD-PUT is sold in sizes from 500 GB to 2 TB.
- Storage capacity
- 500 GB to 2 TB
- Compatible Devices
- PC, Mac, Xbox, PlayStation
- Brand
- Buffalo
- Hardware Interface
- NVMe over UASP
- Warranty
- 2 years
- Read/Write Speeds
- Max 600 MB/s
- SSD speed in a compact flash drive design
- Has LED indicator light
- Excellent read/write performance
- Solid build quality
- Extra effort required to maximize warranty
USB flash drives or thumb drives are extremely appealing portable storage with plug-and-play compatibility. Unfortunately, most of these drives are limited in terms of large-capacity storage or fast file transfer. That's why the Buffalo Portable SSD Stick is so unusual: It has the speed of modern SSDs in an ultra-compact form factor.
The Buffalo Portable SSD Stick is thicker than many flash drives but is still considerably more travel-friendly than external SSDs. Partially collapsing and with a slot to attach to a keychain, it's as convenient as a conventional thumb drive. The manufacturer sells drive capacities ranging from 500 GB to 2 TB, and its read and write speeds impress regardless of size. Real-world tests clock the stick at over 400 MB/s read and write rates, not dramatically short of its theoretical 600 MB/s spec. Buffalo's drive benefits from NVMe over UASP protocol, which matches the performance of larger external and internal SSDs.
With a durable exterior, the SSD Stick will survive regular travel and inevitable drops. It's also well suited as more permanent storage, virtually disappearing from a rear USB 3.0 port on the back of an Xbox Series X. When transferring games onto the console's internal storage, users have an LED indicator that many flash drives lack to confirm drive activity.
Buffalo's SSD is an engineering marvel, succeeding where many other rival USB flash drives fail. If portable SSDs like the Samsung T7 Shield are still too much of a burden, the Buffalo Portable SSD Stick is the best alternative for Xbox Series X storage.
Deciding on the Best SSD or Expandable Storage for Your Xbox Series X
Depending on a buyer's needs, the ways to expand storage on the Xbox Series X are either numerous or barely existent. To sort through the possibilities, remember to consider these essential qualities first:
Expansion Card vs External USB
The only SSDs that allow gamers to boot titles optimized for the Xbox Series X are the Seagate Storage Expansion Card and the WD_Black C50. The Seagate Storage Expansion Card was initially the only no-compromise way to expand the console's storage up to 2 TB. Since its release, the WD_Black C50 has emerged as another Microsoft-endorsed SSD with an even more well-shielded exterior. While these SSDs are somewhat expensive for their added capacity, more spacious external USB SSDs like the Seagate Game Drive Hub can't directly launch recent games.
Capacity
Expansion cards may not offer enough capacity for larger game collections. Gamers will have to sacrifice speed with the Avolusion HDDGear Pro X, but they gain up to 12 TB of storage for less than the cost of the 1 TB Seagate Expansion Card. There are plenty of affordable external USB drives, but the HDDGear Pro X is designed to become a permanent part of an Xbox Series X setup.
Speed
Both the Seagate Storage Expansion Card and WD_Black C50 perform similarly to the Series X's internal storage. File transfers will take considerably longer with a mechanical hard drive like the Avolusion HDDGear Pro X. On the other hand, the Samsung T7 Shield is an extremely durable external NVMe SSD that boasts a high-speed USB 3.2 Gen 2 connection. Xbox gamers must decide whether capacity or speed is more important when shopping for Series X storage.
Portability
One of the many advantages of external SSDs and Xbox expansion cards is how easy they are to transport. The Buffalo SSD-PUT Portable SSD Stick is an extreme example of an SSD's portability, as it's near the size of a tiny USB flash drive. Meanwhile, the heavily protected Samsung T7 Shield is the best choice for frequent travelers who often have to brave the harshest outdoor conditions.
Game ZXC believes the Seagate Storage Expansion Card is the most practical choice for adding Xbox Series X storage. Although cheaper and higher-capacity drives exist, booting recent titles from a hard drive takes priority over archiving game collections.

Q: How many hard drives can you add to Xbox Series X?
Gamers can add a maximum of three external USB drives or SSDs to the Xbox Series X. Adding more storage than that to the console is not recommended, as it could produce warnings about data corruption.
Q: Is SSD or HDD better for gaming?
Most gamers find SSDs far better storage options than older mechanical hard drives. SSDs are faster, more compact, and operate with near silence. However, buyers receive much less storage capacity compared to the costs of traditional hard drives.
