Important
This feature is only available to beta users at this time. The internal M.2 SSD expansion feature will be enabled via an upcoming PS5 system software update. Please check the guide below for more information. Please note that because this is a beta, features and specifications described herein may change prior to the official system software release.
What is an M.2 SSD?
M.2 SSD devices are a high-speed solid state drive medium that PS5 beta users can install to upgrade the storage capacity of their PS5 console or PS5 Digital Edition console (separate purchase required). We recommend verifying that you’ve received a beta invitation before purchasing a new M.2 SSD.
Why add an M.2 SSD to your PS5 console?
Once installed in the PS5 console, M.2 SSD storage can be used to download, copy, and launch PS5 and PS4 games, as well as media apps. This allows you to increase the storage space available to you on your PS5 console. You can freely move games between the PS5 console’s storage, a connected USB extended storage device and the added M.2 SSD storage.
M.2 SSD requirements for PS5 consoles
Interface: PCIe Gen4 x4 M.2 NVMe SSD
Capacity: 250GB – 4TB
Cooling structure: Using an M.2 SSD with your PS5 console requires effective heat dissipation with a cooling structure, such as a heatsink. You can attach one to your M.2 SSD yourself, either in a single-sided format, or double-sided format. There are also M.2 SSDs that have cooling structures (such as heatsinks) built in.
Sequential read speed: 5,500MB/s or faster is recommended
Module width: 22mm width (25mm width
is not supported)
Form Factor: M.2 type 2230, 2242, 2260, 2280 and 22110.
These numbers can be found on retail listings for M.2 SSD devices. The first two digits refer to the width, the remaining digits to the length.
Socket type: Socket 3 (Key M)
Total size including cooling structure:
In millimeters: smaller than 110mm (L) x 25mm (W) x 11.25mm (H).
In inches: smaller than 4.33in (L) x 0.984 in (W) x 0.442in (H).
See below for full requirements.
Length
The following M.2 SSD lengths are compatible with PS5 consoles:
30mm, 42mm, 60mm, 80mm, 110mm (corresponding to the form factor type, per above).
Width
A 22mm-wide M.2 SSD module is required.
The total structure (including an added cooling structure) cannot exceed 25mm (0.984in).
Height
The total height of the M.2 SSD and its cooling structure (such as a heatsink) – whether built-in or separate – must be less than 11.25mm (0.442in).
The height must also be in the right place, in relation to the M.2 SSD’s circuit board:
- The size below the board must be less than 2.45mm (0.096in).
- The total size above the board must be less than 8mm (0.314in).
(Note: millimeter measurements are the technical standard and are more precise than inches. We recommend double-checking that the total dimensions of M.2 SSD and heatsink products you’re considering meet the millimeter requirements before purchasing)
- Both single-sided and double-sided M.2 SSD devices are supported.
- M.2 SATA SSDs aren’t supported.
- You should carefully review drive specifications prior to purchase and contact the vendor or manufacturer if you need further information. SIE cannot guarantee that all M.2 SSD devices meeting the described specifications will work with your console and assumes no responsibility for the selection, performance or use of third-party products.
- Not all games are necessarily playable with the exact same performance provided by the PS5 console’s internal Ultra-High Speed SSD, even where the M.2 SSD device’s sequential read speed is faster than 5500MB/s.
- The majority of M.2 SSD devices with the above type numbers (M Key Type 2230, 2242, 2260, 2280 and 22110) and without a built-in cooling structure will fit the PS5 console’s SSD slot. However, sizes for cooling structures (like heatsinks) vary greatly. If you are not sure an M.2 SSD or cooling structure (such as a heatsink) you’re considering meets the size requirements outlined here, we recommend looking for another product option or contacting the vendor or manufacturer for more information.
If you experience problems while playing a game installed on M.2 SSD storage,
move the game to the internal Ultra-High Speed console storage.
