The PlayStation 5 ships with an 825 GB SSD that is soldered to the board and cannot be replaced. Sony added an empty M.2 expansion slot that accepts a PCIe 4.0 x4 NVMe drive from 250 GB up to 8 TB, so you can add storage without opening the system beyond the cover.
This guide explains the PS5 SSD requirements, how to install and format a compatible drive, and how to clone an existing PS5 expansion SSD to a larger M.2 drive on a PC.
A drive that meets the PCIe 4.0 x4 requirement works even if its raw speed is below the recommended figure, but slower drives will increase load times. SATA M.2 drives are not compatible with the PS5 slot.

Do not format the SSD on a Windows PC for PS5 use. The PS5 uses its own file system, so let the console handle formatting after the drive is installed.

Moving a game is much faster than re-downloading it. Use the Move option when you run low on internal storage instead of deleting and reinstalling titles.
If you already have a PS5 expansion SSD full of games and want a larger one, you cannot clone it inside the PS5. Instead, connect both drives to a PC and clone the old expansion SSD to the new M.2 drive, then put the larger one back into the console.
Watch the video tutorial below to clone the drive step by step with Qiling Disk Master.
Step 1. Open Qiling Disk Master, choose Clone, and then select Disk Clone.

Step 2. Select the old PS5 expansion SSD as the source and click Next.

Step 3. Pick the new larger M.2 SSD as the destination and confirm that its data will be replaced.

Step 4. Use sector-by-sector clone to copy the PS5 file system exactly, including the hidden console partitions.

Step 5. Click Proceed, wait for the copy to finish, then install the cloned M.2 drive back into the PS5.

If the PS5 asks to format the cloned drive, the sector-by-sector copy did not preserve the PS5 partition table. Restart the clone and make sure you selected the full disk, not a single partition.
No. The internal SSD is soldered to the motherboard. You can only add storage through the M.2 expansion slot or a USB drive.
Yes. Sony requires a heatsink on the expansion SSD because the slot has no active cooling inside the console.
No. The cloned M.2 drive only stores games. The PS5 always boots from its internal soldered SSD.
The clone did not copy the full PS5 partition structure. Use a sector-by-sector clone of the entire disk so the console recognizes the file system.
No. The PS5 slot only supports PCIe NVMe M.2 drives. SATA M.2 SSDs are electrically incompatible and will not be detected.
Cloning the PS5 expansion SSD on a PC overwrites the destination and could corrupt the source if a power loss occurs. Back up the disk image first so you can restore if the clone fails.
Watch the video tutorial below to back up Windows and restore it if the clone fails.
Step 1. Open Qiling Disk Master and select Disk Backup to image the entire PS5 expansion SSD.

Step 2. Save the image to a separate large drive and start the backup.

Step 3. Click Proceed to start the disk backup and wait patiently until it finishes. You can also tick Shut down the computer when the operation is completed to power off automatically.

Step 4. If the cloned SSD is not recognized by the PS5, restore the image to a fresh M.2 drive and retry the sector-by-sector clone.

The PS5 internal SSD cannot be replaced, but the M.2 expansion slot accepts a PCIe 4.0 NVMe drive from 250 GB to 8 TB with a required heatsink. Install the drive, let the PS5 format it, and move games from internal storage. To upgrade to a larger expansion SSD, clone the old drive sector by sector on a PC with Qiling Disk Master and reinstall it in the console.
