Quick comparison
How to choose
Internal vs external storage
The most important decision is where you plan to store your games. PS5 and Xbox Series X/S can run next-gen titles directly from an internal M.2 NVMe SSD installed inside the console. External drives connect over USB and work well for storing or archiving games, but PS5 titles must be moved back to internal storage before you can play them. If you want to play directly from the expansion, go internal.
Read speed for internal NVMe drives
For internal M.2 drives, sequential read speeds matter. PS5 requires a PCIe Gen 4 NVMe drive, and Sony recommends speeds of roughly 5,500MB/s or higher. Drives in this guide reach up to around 7,450MB/s. Faster drives can reduce load times, though real-world differences between drives above the minimum threshold are often modest.
Heatsink inclusion
The PS5 expansion slot runs warm during play. Many drives include a heatsink in the box, which can help manage thermals. If a drive you are considering does not include one, budget for a compatible aftermarket heatsink before purchasing.
Capacity vs budget
Internal NVMe drives cost more per terabyte than external hard drives. If you mostly want affordable bulk storage for older PS4 titles or Xbox games, a large external HDD offers the best cost per gigabyte. For a primary play-from-storage solution, spending more on a 2TB or 4TB internal drive reduces how often you juggle titles.
Portability needs
If you move between TVs or travel with a console, a compact external SSD with drop protection and USB-C connectivity is worth the premium over a standard external hard drive.

Frequently asked questions
What is the difference between an internal NVMe SSD and an external hard drive for PS5 or Xbox Series consoles?
An internal NVMe M.2 SSD slots directly into the console expansion bay and runs at speeds up to 7,000MB/s or more, so PS5 and Xbox Series X games load and run from it just like the built-in storage. An external hard drive or external SSD connects over USB and works well for storing games, but on PS5 you have to move a game back to internal storage before playing it. If you want to play next-gen titles directly from expanded storage, an internal NVMe drive is the right choice.
Can you play PS5 games directly from a USB external drive like the Seagate Game Drive or WD Black P10?
Not directly on PS5. Sony currently requires PS5 titles to run from internal NVMe storage, either the built-in SSD or an installed M.2 expansion like the WD Black SN850P or fanxiang 2TB. External USB drives such as the Seagate 5TB or WD Black P10 6TB are useful for storing your PS5 game library and transferring titles back to internal storage when you want to play them. They are also fully compatible for playing PS4 titles on PS5 without any transfer needed.
Does an internal M.2 SSD for PS5 need a heatsink and why does it matter?
Sony recommends installing a heatsink on any M.2 SSD you add to the PS5 expansion slot because the drive sits in an enclosed space where heat can build up during long gaming sessions. Sustained heat can potentially reduce performance or long-term reliability. Several drives in this category, including the WD Black SN850P, fanxiang 2TB, and MOVE SPEED HB7450, include a heatsink in the package, which saves you from sourcing one separately and ensures the drive fits within the slot clearance guidelines.
How do external drives for Xbox Series X and S work compared to PS5 external storage?
Xbox Series X and S consoles allow games to be stored and launched from USB storage, but only titles optimized for those consoles need to be on fast storage to run at full performance. A standard USB hard drive like the YOTUO 750GB can store and launch older Xbox One titles without issues. For Xbox Series X and S optimized games, Microsoft sells a proprietary expansion card slot solution. General USB external drives are still handy for offloading your library and freeing up internal space on either platform.
What storage capacity should you buy and is it worth paying more for a larger drive?
For most players, 2TB to 4TB of internal storage tends to cover a large game library without constant juggling, especially since modern titles can exceed 100GB each. Smaller options like 1TB drives cost less upfront and work well if you rotate your installed games regularly. Larger capacities such as the MOVE SPEED 4TB or WD Black P10 6TB can offer better long-term value per gigabyte and reduce how often you manage what is installed. The right size depends on how many games you keep installed at once and whether you prefer internal or external storage for your setup.
