What you need before you start

Installing an internal hard drive in a PS5 requires a few specific things, and getting them wrong means the drive won't work or you'll damage the console. You need a 2.5-inch SSD (solid state drive) — not a regular hard drive, and not a 3.5-inch drive. The drive must be between 250GB and 8TB in capacity. It also needs to meet Sony's speed requirement: at least 5,500 MB/s read speed. Most modern NVMe SSDs (the kind that look like a stick of gum) meet this, but older or cheaper drives do not.

You'll also need a Phillips head screwdriver — a small one, not a large one. Some people use a magnetic screwdriver to avoid dropping screws into the console, which is a good idea. That's genuinely all the tools you need. You do not need thermal paste, thermal pads, or any other materials. Sony's PS5 design does not require them.

Before you buy a drive, check the exact model number against Sony's official list of compatible drives on their support website. The list changes as new drives are tested. A drive that works today might not be on the list next month, and a drive not on the list might work but could cause problems Sony hasn't tested for. Buying a drive not on the list is a gamble — it might work fine, or it might cause crashes or data loss.

Key Takeaways

  • You need an NVMe SSD between 250GB and 8TB with at least 5,500 MB/s read speed, and it must be on Sony's official compatibility list before you buy it.
  • The PS5 has a dedicated slot on the motherboard; you remove one screw to access it, slide the drive in at an angle, and press down until it clicks.
  • The entire installation takes about five minutes once you have the drive, but you must power off the console completely and unplug it first.
  • After installation, the PS5 will format the drive automatically the first time you turn it on, which takes a few minutes and erases anything on the drive.
  • A new internal drive shows up as "Extended Storage" in your PS5 settings and works the same way as the built-in storage for game installation and play.

Powering down and opening the console

Turn off your PS5 completely — not rest mode, but a full shutdown. Go to the power menu and select "Turn Off PS5". Wait for the light on the front to stop blinking. Then unplug the power cable from the back of the console. This is not optional. You are working inside the machine, and the power needs to be completely cut.

Stand the PS5 upright (the way it normally sits) and look at the right side panel — the one with the curved edge. This panel comes off. Push it toward the back of the console and it will slide off. Set it aside somewhere safe. You now see the interior of the PS5, and you'll see a metal cover with a single screw on it. That screw is what you remove to reach the drive slot.

Use your Phillips screwdriver to remove that one screw. It's small and can roll away easily, so keep track of it. Once the screw is out, the metal cover lifts straight up and off. Underneath, you'll see a slot that looks like a long, narrow opening. This is where the SSD goes. The slot has a small notch at the far end — that's the key that keeps the drive oriented correctly.

Installing the drive itself

Hold your SSD so the gold connector pins face down and the label faces up. The drive should be at roughly a 30-degree angle to the slot — tilted, not flat. Slide it into the slot smoothly and steadily. You'll feel it go in. Once it's fully inserted, press down gently on the end of the drive. It will click into place. The drive should now sit flat in the slot, held down by a clip at the end.

If the drive does not click or does not sit flat, remove it and try again. A drive that's not fully seated will not work. Once it's in and clicked, replace the metal cover and screw it back down. Then slide the side panel back on — it should click into place. Your console now looks normal from the outside, but the drive is installed inside.

Plug the power cable back in and turn on the PS5. The first time you start it with a new drive, the console will detect it and ask you to format it. This process erases anything on the drive and prepares it for use. It takes a few minutes. Let it finish completely. Do not turn off the console during formatting.

What happens after the drive is formatted

Once formatting is done, your new drive shows up in Settings under "Storage" as "Extended Storage". The PS5 treats it exactly like the built-in storage — you can install games on it, play games from it, and move games between the internal drive and the external one. The only difference is that the internal drive is slightly faster, but you won't notice the difference in real-world use.

Games installed on the new drive work the same way as games on the built-in storage. You don't have to do anything special to play them. The PS5 manages both drives automatically. If you ever need to remove the drive, you can do so at any time — just power off, unplug, remove the side panel and metal cover, and slide the drive out. Any games on that drive will no longer be playable until you reinstall them on the internal storage.

Common mistakes that cause problems

The most common mistake is buying a drive that's not on Sony's compatibility list. A drive that's too slow or uses a different interface might appear to work at first, but can cause crashes, freezes, or data loss. The second most common mistake is not fully seating the drive — it looks like it's in, but it's not clicked all the way down. The console won't recognize it, or it will work intermittently. If your PS5 doesn't detect the drive after installation, power off, unplug, and check that the drive is fully seated and clicked.

Another mistake is trying to install the drive while the console is in rest mode or still has power running to it. The PS5 must be completely powered off and unplugged. Working on a powered machine risks damaging the drive or the console. Finally, some people try to add thermal pads or thermal paste to the drive. The PS5 design does not need these, and adding them can actually cause heat management problems. Install the drive as-is, with nothing added.

Checking your work

After the drive is formatted and the console has restarted, go to Settings, then Storage, then Extended Storage. You should see your new drive listed with its capacity. The PS5 will show how much space is used and how much is free. If the drive doesn't show up here, power off and unplug again, then check that the drive is fully seated in the slot and clicked down. If it still doesn't appear, the drive may not be compatible or may be faulty.

You can also check the drive's speed in Settings under System Software. The PS5 will display the read speed of your new drive. It should match or exceed the 5,500 MB/s minimum. If it shows a much lower speed, the drive may not be fully compatible, even if it's on the official list. Contact Sony support if the speed is significantly lower than expected.

Frequently Asked Questions

Do I need to format the drive before I install it?

No. The PS5 formats the drive automatically the first time you turn on the console after installation. You should not format it yourself beforehand. If you do, the PS5 will format it again anyway.

Can I use a regular 2.5-inch hard drive instead of an SSD?

No. The PS5 requires an NVMe SSD specifically. A regular hard drive or a 2.5-inch SATA SSD will not work. The slot is designed for NVMe drives only.

What happens to my games if I remove the internal drive?

Games stored on the removed drive will no longer be playable. You can reinstall them on the internal storage or on a new drive, but you'll need the game files again. Your save data is stored separately and won't be lost.

Is it safe to install the drive myself, or should I take it to a repair shop?

It's safe to install yourself if you follow the steps carefully. The process is straightforward and takes about five minutes. You're not soldering anything or opening any sealed components. Just make sure the console is completely powered off and unplugged before you start.

How much storage should I buy?

That depends on how many games you want to install. Modern games range from 50GB to 150GB each. A 1TB drive gives you room for roughly 5 to 10 games depending on their size. A 2TB drive gives you roughly 10 to 20 games. The PS5's internal storage is 825GB, so adding a 1TB or 2TB drive roughly doubles or triples your total space.
