Although PCIe Gen3 M.2 SSD products also have the option of Key M, they can be installed with ease, but they can not function in a PS5! So you still have to make sure it’s GEN4 before you can use it!

The installation of the A440 PSS White Warrior M.2 PCIe4.0 SSD can be found in the following video.


How to connect the portable T-FORCE M200 Sniper Mobile SSD to PS5? You have 3 USB ports to choose from: a USB Type-C port on the front of the PS5 console, and two USB type-A ports on the back of the console.

  2. You can connect multiple portable SSDs to the PS5 console at the same time, but only one device can be used at a time.
  3. Front USB type-A can be used for other USB devices such at PS5 joystick charging, PlayStation VR or wireless headset adapters. For more details on the compatibility of the USB device with the ports on the PS5 console, please refer to the PlayStation official website.\

2. How can I use M.2 SSD on PS5?

The following screenshot shows the operation screen using A440 PSS White Warrior M.2 PCIe4.0 SSD.

After successfully installing the M.2 SSD in the PS5, this formatting screen will appear at the beginning. PS5 bootup and requires formatting before it can be used, so remember to empty or back up the data in the M.2 SSD first


If your game is a disk copy, you still need the actual disk to play even if you move it to the M.2 SSD. The digital version of the game will not have this problem.


In addition to helping to release the storage space of the PS5 console, you can also play, download and update PS4 or PS5 games on the M.2 SSD directly, without having to move back to the console to operate, which is very convenient.


Why is the speed of moving games from PS5 to M.2 SSD is so much faster than M.2 to PS5?

Because the storage device on the PS5 itself requires a read speed much faster than the write speed, so when you move the game to M.2 SSD, the PS5 is doing the reading, while the M.2 SSD is doing the write, which is why it takes less time.

When we play games, we are doing the action of reading, so in short it will not affect your enjoyment of playing games at all!

3. How can I use portable SSD on PS5?

The following screenshot shows the operation screen using T-FORCE M200 Sniper Mobile SSD.

When a portable SSD is connected to PS5 for the first time, there will be a formatting requirement as well, so make sure that the data on the portable SSD is properly handled! If the formatting screen does not pop up at the start, go to Settings> Storage> USB Extended Storage> and then select Format to perform.


The portable SSD, like the M.2 SSD, can store PS4 and PS5 games and game save files, but you can only play and install PS4 games on the portable SDD. PS5 games cannot be played on portable SSD.


Therefore, it is recommended to use the portable SSD to move games in PS4 to PS5 to play. In addition to playing on an external device directly after connecting to PS5, saving time for reinstallation, it also allows more PS5 games to be installed in the storage of the PS5 itself.


Before you remove the portable SSD, first make sure the power light of PS5 or PS4 game console is completely off before unplugging the device. If you want to unplug the external storage device while the game console is running, you need to go to the setup screen and exit the device. The related steps are provided below.

PS5:Settings > Storage > USB Extended Storage > Safely Remove from PS5

PS4:Settings > Devices > USB Storage Devices > Stop

It is recommended to format on PS5 first before accessing the game on PS4, so that you will not have to do it again because of formatting when moving to PS5
