Quick comparison
How to choose
Internal vs External Use
Internal NVMe M.2 drives slot directly into the PS5 expansion bay and let you play PS5 titles natively from the added storage, while external USB drives can only store and transfer PS5 games (you must move them back to internal storage to play). External drives are the only option for Xbox Series consoles without a proprietary expansion card slot, so confirm which console you own and what you actually need the storage to do before choosing a form factor.
Read Speed and Gen Support
PS5 internal expansion requires a PCIe Gen 4 NVMe drive and Sony recommends sequential read speeds of around 5,500MB/s or higher to keep pace with the console. Drives rated at 7,000MB/s or above offer headroom above that threshold, while slower Gen 3 drives may not be accepted by the console at all. For external USB drives, speed matters far less since they serve as a library or backup rather than an active game runner.
Capacity vs Budget Fit
Modern PS5 and Xbox games commonly exceed 50GB each, so a 1TB expansion fills up faster than it might seem, especially if you rotate between large titles. Weighing whether you want one high capacity drive or a smaller internal drive paired with a large external archive can stretch your budget further depending on your library size. Consider roughly how many games you keep installed at once before settling on a size.
Heatsink Inclusion
The PS5 internal expansion bay requires a heatsink to manage thermal output from a fast NVMe drive during extended play sessions. Some drives include a heatsink in the box, which saves a separate purchase and guarantees a fit within the PS5 bay clearance limits. If a drive you are considering does not include one, budget for a compatible low profile heatsink before buying.
Official Licensing and Compatibility
Officially licensed drives have been tested against console firmware requirements and carry a lower risk of compatibility surprises after system updates. Third party drives can work well but should at minimum meet the console maker’s published specifications for interface type, form factor (M.2 2280 for PS5 internal), and speed thresholds. For external drives, confirm the USB standard matches your console’s ports so you get the advertised transfer speed rather than a slower fallback mode.

Frequently asked questions
What is the difference between an internal M.2 SSD and an external hard drive for PS5 storage expansion?
The core difference is where and how your games run. An internal M.2 SSD installed in the PS5 expansion slot, such as the WD_BLACK SN850P or the fanxiang 2TB NVMe, lets you launch and play PS5 titles directly from that drive at speeds up to 7,300MB/s, matching the console’s own storage performance. An external USB drive like the Seagate Game Drive or WD_BLACK P10 can store PS5 games but requires you to copy them back to internal storage before playing them. External drives are better suited for storing PS4 games, which can run directly from USB, or for archiving titles you rotate in and out.
How hard is it to install an M.2 SSD inside a PS5, and do you need a heatsink?
Installing an M.2 SSD in a PS5 requires removing the side panel, a single screw to seat the drive, and replacing the panel, which typically takes under 15 minutes with a small Phillips screwdriver. Sony requires a heatsink to keep the drive within safe operating temperatures, which is why options like the WD_BLACK SN850P and fanxiang 2TB NVMe ship with one already attached. If you buy a bare drive you will need to add a heatsink separately before installing it. Overall the process is straightforward and well documented in Sony’s official instructions.
Can external storage drives like the WD_BLACK P10 or Seagate Game Drive be used with both PS5 and Xbox Series consoles?
Most external USB hard drives are formatted for one platform out of the box but can be reformatted to switch ecosystems, though doing so erases all data on the drive. The WD_BLACK P10 6TB is marketed for PlayStation use while the YOTUO portable HDD lists compatibility with PS4, PS5, Xbox One, and Xbox Series X/S, making it a more cross-platform option for gamers who own multiple consoles. Xbox Series X and S also support a proprietary internal expansion card slot that external USB drives cannot replace for running Xbox Series optimized titles natively. For cross-platform archiving, a USB 3.0 or 3.2 external drive tends to be the most flexible and affordable path.
Is a portable external SSD like the SanDisk Extreme worth the extra cost over a standard external hard drive for PS5 storage?
For PS5 use specifically, a portable external SSD such as the SanDisk 1TB Extreme Portable SSD offers faster transfer speeds, around 1,000MB/s over USB 3.2 Gen 2, which makes copying games between drives noticeably quicker compared to a traditional spinning hard drive at roughly 100 to 150MB/s. Neither type can run PS5 native titles directly from the external connection regardless of speed, so the primary benefit shows up during game transfers and accessing PS4 titles. The SanDisk also adds drop protection, which matters if you travel with it. If you mostly leave the drive on a shelf at home and only need bulk storage for archiving, a higher capacity HDD at a lower price per terabyte may make more practical sense.
How much internal M.2 SSD capacity do you actually need for a PS5 expansion, 1TB, 2TB, or 4TB?
The right capacity depends on how many large modern titles you keep installed at once, since many PS5 games now range from 50GB to over 100GB each. A 1TB drive like the WD_BLACK SN850P adds room for roughly 10 to 15 average sized games on top of the console’s built-in storage. A 2TB option such as the fanxiang NVMe roughly doubles that headroom and suits players who prefer not to delete and reinstall frequently. The MOVE SPEED 4TB drive is aimed at heavy collectors or those who want to avoid managing storage for years, though the cost per terabyte is worth comparing across sizes before committing.
