The Best PS5 Storage Upgrades: NVMe SSDs That Unlock More Space (and Speed) for Your PlayStation 5
If you’ve ever paused an install to decide which 100 GB game to delete, you’re not alone. Modern PS5 titles are massive, and the stock internal storage fills up fast. The good news: Sony built the PS5 with a high-speed M.2 slot, so you can add a Gen4 NVMe SSD that matches the console’s blistering load times—no compromises. Below, we break down exactly what to look for, how to install the right drive, and our picks for the best PS5-ready SSDs.
Why PS5 storage expansion matters
AAA games frequently pass 80–120 GB, seasonal updates can weigh tens of gigabytes, and live-service titles balloon over time. Expanding storage means you spend less time juggling installs and more time playing. The right M.2 NVMe drive keeps the native PS5 experience intact—fast boot, near-instant level loads, and seamless texture streaming—because it runs at or above the PS5’s expected read performance threshold.
Crucially, only PCIe Gen4 M.2 NVMe SSDs that meet Sony’s spec can play PS5 games. External USB SSDs are great for PS4 titles and cold storage for PS5 games, but you can’t launch PS5 games from external USB.
Internal NVMe vs. external SSD: what you need to know
- NVMe (Non-Volatile Memory Express) SSDs use the PCIe bus and deliver extremely high sequential reads—exactly what the PS5’s I/O pipeline expects for assets and textures. Sony recommends drives with a sequential read of 5,500 MB/s or higher, plus a heatsink that fits the M.2 bay.
- SATA and USB SSDs are much slower. Even fast USB 3.2 external SSDs (typically 500–1,050 MB/s) are fantastic for running PS4 games or storing PS5 titles you’re not actively playing. But PS5 games must run from the internal SSD or a qualified M.2 NVMe expansion drive.
- Heatsink matters. Sustained reads/writes and shader compilation can raise thermals. A low-profile, PS5-compatible heatsink helps maintain performance and longevity.
How to shop: speed, fit, thermals, and value
- Performance: Look for Gen4 x4 NVMe drives with advertised reads ≥ 7,000 MB/s. That headroom helps ensure you meet or exceed the PS5’s requirement even under warm conditions or when the SLC cache is busy.
- Physical fit: The PS5 accepts M.2 2230/2242/2260/2280/22110 lengths and a maximum total module height around 11.25 mm (about 8 mm above the PCB, 2.45 mm below). Heatsinks must be low-profile and within spec.
- Capacity strategy: 1 TB is a solid minimum for frequent players. 2 TB is the sweet spot for most libraries and usually offers a better cost-per-GB than small drives. Entry 500 GB options work for light libraries or secondary profiles.
- Sustained performance: Drives with strong controllers and TLC NAND keep speeds steadier during long installs or massive updates. Some models throttle earlier without a good heatsink.
- Price-per-gigabyte: Officially licensed models typically command a premium. Non-licensed, PS5-compatible drives often offer similar real-world gaming performance at a better $/GB.
Selection criteria (how we picked)
- Verified PS5 compatibility (PCIe Gen4 x4, M.2 form factor, heatsink fit).
- Sequential read speeds that meet or exceed 5,500 MB/s, with real-world gaming parity.
- Thermal design suitable for the PS5’s M.2 bay (pre-installed or included heatsink preferred).
- Capacity options that make sense for different budgets and libraries.
- Proven reliability and firmware support from reputable brands.
- Value measured as performance plus cost-per-gigabyte, not just headline speeds.

That said, the smallest capacity can become restrictive fast—especially for live-service games. Consider it for a secondary console, lighter libraries, or if you plan to offload rarely played titles to external USB storage.
4. WD_BLACK SN850P 2TB NVMe M.2 SSD — Official PS5 Storage Expansion (Heatsink)
The SN850P is Western Digital’s officially licensed PS5 drive, designed and validated specifically for Sony’s thermal and spatial constraints. For buyers who prioritize maximum compatibility confidence, the SN850P removes any guesswork—install, format, and play.
Performance is right up there with the best Gen4 SSDs. The main tradeoff is value: you’re often paying for that official seal. If you want a premium, worry-free 2TB upgrade with branding to match, this is it.
5. Western Digital SN850 2TB NVMe SSD for PS5 with Heatsink — up to 7,000 MB/s
The 2TB SN850 is a workhorse: fast, reliable, and big enough for a rotating lineup of blockbuster titles. Paired with a ready-to-fit heatsink, it installs in minutes and maintains PS5-native responsiveness across loads and level transitions.
It’s not the newest WD_BLACK, but for most players the difference between this and the latest-gen siblings won’t show up in day-to-day gameplay. If you want spacious capacity and strong performance with a track record, it’s an excellent pick.
6. Seagate 1TB NVMe Expansion Card for Xbox Series X|S — Not for PS5
Important clarification: this Seagate card is purpose-built for Xbox Series X|S and cannot expand PS5 storage. The PS5 requires a standard M.2 PCIe Gen4 NVMe SSD installed inside the console’s expansion bay. If you’re shopping for a PlayStation 5, skip this model and choose one of the PS5-ready drives above.
PS5 M.2 SSD installation and formatting: step-by-step
- Power down and unplug: Fully turn off your PS5. Unplug all cables and wait for the power indicator to go dark.
- Prep a clean workspace: Ground yourself to reduce static. Place the console on a soft surface with the logo side down and the power button facing away from you.
- Remove the cover: Gently lift the opposite corner and slide off the side panel to reveal the fan and M.2 bay cover.
- Open the M.2 bay: Unscrew the small metal cover. Remove the spacer screw and position it to match your drive length (2230/2242/2260/2280/22110).
- Insert the SSD: Align the notch and insert the M.2 drive at about a 30-degree angle. Press it down and secure it with the screw at the appropriate spacer position.
- Confirm heatsink fit: Ensure the integrated or added heatsink is within height limits and sits flush. Do not over-tighten screws.
- Reassemble: Replace the M.2 bay cover and the PS5 side panel. Reattach cables and stand if used.
- Format on boot: Power on. The PS5 should detect the new drive and prompt you to format it. Follow the on-screen steps; the console will also run a speed test.
- Manage storage: Go to Settings > Storage to move games between Console Storage, M.2 SSD Storage, and USB Extended Storage. Set a default install location if you prefer the M.2.
Tip: If the PS5 doesn’t recognize the drive, reseat it, verify the spacer position, and confirm the heatsink isn’t obstructing the cover.
NVMe vs. other SSDs: the practical differences for PS5
- NVMe Gen4 x4: Uses PCIe lanes for very high bandwidth and low latency. This is what PS5 requires to run PS5 games from an expansion drive.
- SATA SSD (2.5-inch or M.2 SATA): Not supported in the PS5 bay. Over USB, it works as extended storage for PS4 titles and PS5 cold storage, but not for playing PS5 games.
- USB external SSD: Great for PS4 game libraries and offloading PS5 games to free space. Even fast USB 3.x drives are far below the PS5’s internal NVMe speeds and cannot launch PS5 titles.
If your goal is playing PS5 games from added storage, you need a PS5-compliant M.2 NVMe drive with a proper heatsink.
Performance, thermals, and value at a glance
- Speed headroom matters: Drives with advertised reads around 7,000–7,300 MB/s tend to meet or exceed the PS5’s needs even under thermal load. That translates to near-identical load times versus the internal SSD.
- Thermal design: Low-profile, well-finned heatsinks help sustain performance during long installs or shader compilation. The models above include heatsinks engineered to clear the PS5’s cover.
- Capacity economics: 2TB often strikes the best balance between convenience and $/GB. 1TB is the minimum comfortable size for frequent players. 500GB is best reserved for light libraries or secondary consoles.
- Official license vs. value: Officially licensed models (like SN850P) offer guaranteed fit and tuning but tend to cost more than equally fast, non-licensed alternatives.
FAQ
- Can I run PS5 games from a USB external SSD?
No. You can store PS5 games on USB external drives (cold storage) and play PS4 games from them, but PS5 titles must run from internal console storage or a compatible M.2 NVMe SSD installed inside the PS5.
- Do I need a heatsink?
Yes. Sony requires a heatsink for sustained performance and longevity. Choose a model with a pre-installed, PS5-compatible heatsink or add a low-profile heatsink that fits the M.2 bay height and length constraints.
- What capacity should I buy?
For most players, 2TB offers the best comfort and value over time. If budget is tighter or your library is smaller, 1TB still feels like a major upgrade. Use 500GB for lighter libraries or a second console.
- The PS5’s speed test shows a lower number than the box—should I worry?
Not necessarily. The PS5’s test is a quick internal measure and can differ from vendor “up to” specs. If the drive meets Sony’s requirements and formats successfully, game loads and streaming should be on target.
- How do I move games between storage locations?
Settings > Storage lets you move games between Console Storage, M.2 SSD Storage, and USB Extended Storage. You can also set the default install location for new PS5 games and data.
