You can expand your PS5 Slim storage by installing a PCIe Gen 4 M.2 NVMe SSD with a heatsink into the dedicated expansion slot located behind the console’s detachable cover.
New console owners often hit a wall quickly. The internal storage fills up after downloading just a few massive AAA titles. Sony designed the system with a dedicated slot for this exact problem. You do not need to replace the existing drive or delete your favorite games. Adding a secondary drive is a standard process that takes about fifteen minutes and requires only a single tool.
Hardware Requirements For The SSD
You cannot use just any hard drive found in a laptop. The PlayStation 5 Slim requires specific speeds to match the internal architecture. If the drive is too slow, games will stutter or fail to load.
Required specifications:
- Interface — PCIe Gen4 x4 M.2 NVMe SSD. Gen 3 drives will not work.
- Capacity — 250GB minimum, up to 8TB maximum.
- Read Speed — Sony recommends 5,500 MB/s or faster. Most modern drives hit 7,000 MB/s.
- Socket Type — Socket 3 (Key M).
- Form Factor — 2230, 2242, 2260, 2280, or 22110 (2280 is the most common standard).
Why You Need A Heatsink
The SSD slot inside the console has very little airflow. These high-speed drives generate significant heat during heavy gaming sessions. Without a way to dissipate that heat, the drive will throttle its speed to protect itself, causing game crashes or performance drops.
Many drives come with a heatsink pre-installed. If you buy a drive without one, you must purchase and attach a third-party heatsink before installation. The combined height of the drive and cooling structure must be less than 11.25mm (0.44 inches) to fit under the metal cover.
Tools And Preparation Before You Start
Gather everything on a clean, well-lit surface. You should work on a table clear of clutter to avoid losing small screws.
What to grab:
- A #1 Phillips screwdriver — A standard size for electronics. Avoid using a drill.
- A flashlight — Helpful for seeing the screw mounting hole inside the dark slot.
- The PS5 Slim Console — Ensure it is powered off completely, not just in Rest Mode.
Safety check:
Unplug all cables from the back of the unit. Touch a grounded metal object, like a lamp base or the metal leg of a table, to discharge static electricity from your body. Static shocks can damage internal components.
Guide to PS5 Slim Hard Drive Upgrade Steps
The Slim model differs slightly from the original bulky launch model. The outer shell is divided into four panels rather than two large ones. You need to remove the correct panel to access the expansion bay.
1. Position The Console Correctly
Place the PS5 Slim on a soft cloth or mousepad to prevent scratching the side plates. Position the console so the disc drive slot (if you have one) is facing away from you and the power button area is to your right. You want the bottom of the console facing up.
The expansion slot sits beneath the panel that covers the disc drive. On the Digital Edition, it is the bottom-right panel when the console is horizontal and the back ports are facing you.
2. Remove The Cover Panel
This part often feels scary for first-time builders, but the plastic is durable.
- Locate the grip point — Find the edge of the panel near the “feet” or the back ports.
- Lift and slide — Gently lift the edge of the cover up while sliding it toward the opposite side. You will hear a distinct pop as the clips release.
- Set aside — Place the plastic cover safely out of the way.
3. Open The Expansion Slot
You will see a rectangular metal cover held down by a single screw. This protects the M.2 expansion bay.
- Remove the screw — Use your #1 Phillips screwdriver to take out the screw holding the metal plate.
- Remove the plate — Lift the metal cover off and set it aside with its screw.
- Adjust the spacer — Inside the slot, you will see a small metal ring (spacer) and a screw sitting in the hole marked “110”. Remove both. Place the spacer into the hole labeled “80” (or whatever matches your drive length, usually 80 for standard drives).
For detailed diagrams on these ports, you can check Sony’s official hardware guide which highlights the specific screw locations.
4. Insert The M.2 SSD
This is the main event. Handle the SSD by its edges; try not to touch the gold connector pins.
- Align the drive — Line up the notch on the SSD connectors with the small notch in the expansion slot.
- Insert at an angle — Hold the drive at a slight upward angle (about 15 degrees) and push it firmly into the connector. It should slide in without forcing.
- Press down — Once seated, gently press the other end of the drive down until it rests flat on the metal spacer you positioned earlier.
- Secure with screw — Insert the screw through the semi-circle notch on the SSD and tighten it into the spacer. Do not overtighten; stop when it feels snug.
5. Close The Console
You are almost done. You just need to seal the unit back up.
- Replace metal cover — Put the rectangular metal expansion slot cover back in place and secure it with its screw.
- Snap the shell back — Take the white plastic outer panel. Align the hooks with the holes on the console body. Slide it back into place until you hear a solid click.
Formatting The New Storage
The hardware part is finished. Now the software needs to recognize the new device. Reconnect the power and HDMI cables and turn on your TV.
System startup process:
- Power on — Press the PS button on your controller.
- Format prompt — The system will detect the new drive immediately. A screen will appear stating “M.2 SSD Storage.”
- Select Format — Choose “Format M.2 SSD” using your controller. Do not turn off the power during this phase.
- Speed test — After formatting, the PS5 will run a quick read speed test. It usually displays a number around 6,000 MB/s or higher. Select OK.
If you do not see the format screen and the console boots normally, turn it off and reseat the drive. It likely did not click fully into the socket.
Managing Your Game Installations
Your new drive acts as a seamless extension of the console. You can play PS5 and PS4 games directly from this new storage. However, the console will default to downloading new games to the internal storage unless you change the settings.
Setting Default Install Location
To make the new drive your primary destination:
- Go to Settings — Select the gear icon in the top right of the home screen.
- Select Storage — Scroll down to the Storage option.
- Installation Location — Navigate to “Installation Location.”
- Change preference — Set “PS5 Games and Apps” to “M.2 SSD Storage.” You can do the same for PS4 games.
Moving Existing Games
You likely want to free up space on the main drive by moving older titles to the new one.
- Open Console Storage — In the Storage menu, select “Console Storage” and then “Games and Apps.”
- Select items — Tab over to “Move Games.” Check the boxes next to the games you want to transfer.
- Confirm move — Select “Move.” The copy speed is incredibly fast thanks to the Gen 4 architecture.
Troubleshooting Common Issues
Sometimes things do not go according to plan. Here are the fixes for the most frequent hiccups during a PS5 Slim hard drive upgrade.
Drive not recognized:
If the console boots but ignores the drive, the connection is usually loose. Open the bay again. Unscrew the drive, pull it out, and re-insert it with a firm push. The gold pins should almost disappear into the slot.
Error code CE-107880-4:
This error specifically means the drive you installed is too slow or not compatible. Double-check the box your drive came in. If it says “PCIe Gen 3,” it will not work. You must return it for a Gen 4 model.
Overheating warning:
If you receive messages about the M.2 SSD getting too hot, check the heatsink. Did you remove the plastic film from the thermal pad before attaching the heatsink? If that film remains, heat cannot escape the drive.
Tech outlets like Tom’s Hardware frequently test these drives and confirm that without a heatsink, performance drops significantly within minutes of gameplay.
Final Thoughts On Storage
Adding this drive is a permanent fix for storage anxiety. You avoid the constant cycle of deleting and redownloading 100GB files. Because the M.2 drive matches the internal speed, you will notice zero difference in load times or texture pop-in. The console treats both storage pools as one high-speed ecosystem.
