Knowing how to install a PS5 SSD is one of the best upgrades any PlayStation 5 owner can make. Modern games easily pass 100GB, so the stock drive fills up fast.
The good news is Sony made the PS5 expansion slot easy to access, which means you can add an M.2 NVMe SSD in about 15 minutes with one screwdriver.
This guide walks through the full process for both the original PS5 and the PS5 Slim, including what specs your SSD needs and how to format it once installed.
TL;DR: Key Takeaways
- You need an M.2 NVMe SSD with PCIe Gen4 x4 and at least 5,500MB/s sequential read speed.
- The drive must have a heatsink, either built in or attached separately.
- M.2 sizes 2230, 2242, 2260, 2280, and 22110 are supported, with 2280 being the most common.
- Maximum size with heatsink is 110mm long, 25mm wide, and 11.25mm thick.
- You only need a #1 Phillips screwdriver for the physical installation.
- Installation takes about 10 to 15 minutes, and formatting usually takes another 1 to 2 minutes.
- PS5 games can be played directly from the newly installed M.2 SSD.
Before You Start: PS5 SSD Requirements
Sony has clear rules for which SSDs work in the PS5. If you use the wrong drive type, the console may reject it, fail to format it, or run it below the speed needed for modern PS5 games.
What your SSD must have
- Interface: M.2 NVMe SSD with PCIe Gen 4. Gen 5 drives can work, but they will run at Gen 4 speeds inside the console.
- Sequential read speed: 5,500 MB/s minimum.
- Form factor: 2230, 2242, 2260, 2280, or 22110.
- Capacity: 250GB to 8TB, with 1TB and 2TB being the most practical sizes for most players.
- Cooling: A built-in or aftermarket heatsink is required.
- Maximum dimensions with heatsink: 110mm long, 25mm wide, and 11.25mm thick total.
What does not work
- M.2 SATA SSDs
- PCIe Gen 3 NVMe SSDs
- Drives without a heatsink
- Oversized heatsinks taller than 11.25mm

What You Need Before Starting
Gather everything before opening the console so the install goes smoothly.
- A #1 Phillips screwdriver, also called a cross-head screwdriver
- Your M.2 NVMe SSD with a heatsink already installed
- A flat, clean, well-lit surface with a soft cloth or towel
- A small flashlight if you want better visibility inside the slot area
- An anti-static wrist strap, or at least touch a grounded metal object before you begin
Smart extra step: Back up your save data to PlayStation Plus cloud storage or an external USB drive before you begin. You probably will not lose anything during installation, but it is still the safer move.
How to Install a PS5 SSD: Step by Step
The process differs slightly between the original PS5 (released 2020) and the PS5 Slim (released 2023). Here is each version.
Power down completely
Press and hold the power button until you hear two beeps and the console turns off. Do not use Rest Mode for this job.
Unplug everything
Remove the power cable, HDMI cable, USB devices, and controllers. Let the console cool for at least 5 to 10 minutes.
Lay the PS5 flat
Position it with the PS logo facing down and the power button facing away from you. Remove the base stand first.
Remove the white side panel
Hold the upper-left and lower-right corners, lift slightly, then slide the panel toward you until it releases with a small click.
Find the expansion slot cover
Look for the long rectangular metal cover with one screw near the cooling fan.
Remove the cover screw
Lift the metal cover carefully and keep the screw somewhere safe so it does not fall into the fan area.
Locate the M.2 slot
You should now see the green M.2 area with the connector on the right side and the spacer screw on the left.
Move the spacer if needed
Reposition the spacer screw to match your SSD length. For most drives, that will be the 80mm position for 2280.
Insert the SSD
Hold the SSD by the edges, line up the notch, and insert it into the connector at about a 30-degree angle.
Press the SSD flat
Push the free end down until it sits flush with the spacer.
Secure the SSD with the screw
Tighten the screw until snug. Do not overtighten it.
Replace the metal expansion cover
Put the cover back in place and tighten its screw.
Slide the side panel back on
Place it slightly off the top edge and slide it down until it clicks into position.
Reconnect everything and power on
Reattach the base, plug your cables back in, and start the console.
PS5 Slim Installation Steps
The PS5 Slim is similar, but the cover removal is slightly different. The internal M.2 process is the same once you reach the expansion cover.
Power down completely
Use the same full shutdown process as the original model and avoid Rest Mode.
Unplug the console and let it cool
Remove all connected cables and give the console time to cool before opening it.
Lay the Slim flat
Keep the PS logo facing down, the power button away from you, and the disc drive on the right if you have the disc version.
Remove the bottom cover first
On the Slim, the M.2 slot is accessed through the smaller bottom cover section near the base. Slide it off carefully.
Continue with the same internal M.2 steps
From the expansion cover onward, follow the same install process used for the original PS5.

Formatting the SSD After Installation
When you first power on the PS5 after installing the drive, the console should detect it automatically and prompt you to format it.
Power on the PS5
Start the console as normal after reassembly.
Confirm the format prompt
A message will appear on screen asking to format the new SSD. Press X to continue.
Wait for formatting to finish
This usually takes 30 to 90 seconds.
Check the speed test result
The PS5 will run a quick read speed test after formatting. Your result should be at or above 5,500 MB/s.
Start using the drive
Once the format is complete, the SSD is ready for PS5 and PS4 games.
Important: Do not turn off the PS5 during formatting. Interrupting this process can corrupt the drive or cause console storage issues.
If the SSD fails the speed test, common reasons include using the wrong drive type, poor heatsink contact, or a damaged or counterfeit SSD.
Setting the New SSD as the Default Install Location
By default, the PS5 may still install games to internal storage. You can switch the default destination in a few quick steps.
To change the default install location
- Go to Settings
- Select Storage
- Choose Installation Location
- For PS5 Games, choose M.2 SSD Storage
- Repeat the same setup for PS4 games and apps if you want them saved there too
To move existing games
- Go to Settings > Storage > Console Storage > Games and Apps
- Select the games you want to move
- Choose Move > M.2 SSD Storage
PS5 SSD Specs at a Glance
Use this quick table if you want a fast way to compare your SSD against Sony's compatibility requirements.
| Spec | Required Value | Notes |
|---|---|---|
| Interface | M.2 NVMe (PCIe Gen 4 x4) | Gen 5 drives can work, but they run at Gen 4 speeds in the PS5. |
| Sequential read speed | 5,500 MB/s minimum | Higher speeds are fine, though going far past 7,000 MB/s brings little real-world gain. |
| Form factor | 2230, 2242, 2260, 2280, or 22110 | 2280 is the most common and easiest to shop for. |
| Capacity | 250GB to 8TB | 1TB and 2TB are the sweet spot for most players. |
| Heat dissipation | Required | Use a drive with a built-in heatsink or a properly fitted aftermarket heatsink. |
| Single or double-sided | Both supported | Single-sided drives are often easier to fit comfortably. |
| Maximum dimensions with heatsink | 110mm L x 25mm W x 11.25mm H | That includes 8mm above the board and 2.45mm below. |
| Host Memory Buffer (HMB) | Not supported | Drives that rely on HMB can run slower in the PS5. |

Troubleshooting Common PS5 SSD Issues
If the install does not go smoothly, these are the most common issues and the fixes most people need first.
| Problem | Likely Cause | Fix |
|---|---|---|
| PS5 does not detect SSD | The drive is not seated fully | Power off, remove the drive, reseat it fully in the connector, and make sure it sits flush at the spacer. |
| Format failed message | Wrong SSD type or speed | Confirm the drive is PCIe Gen 4 NVMe and rated for at least 5,500 MB/s sequential read speed. |
| Speed test fails | Bad heatsink contact | Reattach the heatsink and check that the thermal pads are touching the controller and NAND properly. |
| Repair storage prompt | Drive was not formatted correctly | Go to Settings > Storage > M.2 SSD and format the drive again. |
| Game crashes from SSD | Heat throttling or HMB drive | Move the game temporarily to internal storage, then test again. If the issue continues, replace the drive with a better PS5-compatible model. |
| Slower load times than expected | HMB-dependent drive | Use a drive with onboard DRAM cache for more stable performance. |
| Console temperature warnings | Heatsink is too tall or blocks airflow | Replace it with one that stays under the total 11.25mm height limit. |
| Drive disappears after sleep | Loose connection | Power the console down and reseat the SSD firmly. |
Why a Heatsink Is Not Optional
Sony requires a heat dissipation solution for any SSD used in the PS5 expansion slot, and that rule matters in real use. A fast PCIe Gen 4 SSD can run very hot during long gaming sessions, especially inside a compact console bay with limited airflow.
- Without proper cooling, an SSD can reach very high temperatures.
- When that happens, the drive may throttle to protect itself, cutting performance by 30 to 50 percent.
- Long-term heat stress can shorten the usable life of the SSD.
Your two heatsink options
- Built-in heatsink SSD: easier installation and cleaner fit
- Aftermarket heatsink: useful if you already own a bare drive, but installation has to be done carefully

What If You Cannot Open the PS5? External SSD Option
If you do not want to open the console, an external USB SSD still gives you more storage, but it works differently from an internal M.2 upgrade.
External SSD works well for
- Storing PS5 games you are not actively playing
- Playing PS4 games directly over USB
- Moving games around without downloading them again
External SSD does not work for
- Playing PS5 games directly from the external drive

Final Thoughts
Installing a PS5 SSD is one of the easiest hardware upgrades you can make on a modern console. Sony designed the system so users can expand storage without special tools, soldering, or a complicated teardown.
The two most important things are choosing a compatible Gen 4 NVMe drive with a heatsink and seating it properly so the console detects it the first time.
Once the new SSD is installed and formatted, it feels like part of the original storage. You can install games, download updates, and launch PS5 titles directly from it. If you are tired of deleting large games every few weeks, adding more fast storage is one of the most practical upgrades you can make.
