It’s been eight months since Sony released the PS5, and the com­pa­ny is final­ly launch­ing a firmware update for beta PS5 users that enables inter­nal SSD expan­sion using con­sumer NVMe M.2 SSDs. The update is cur­rent­ly rolling out across sup­port­ed regions, and if you want to try this fea­ture, you’ll need to be signed up for the beta program

The tests will be impor­tant as Sony will eval­u­ate dif­fer­ent types of SSDs from a num­ber of man­u­fac­tur­ers in order to deter­mine what’s best for own­ers mov­ing for­ward. Of course, this means there isn’t a list of sup­port­ed SSDs, but sev­er­al para­me­ters were giv­en by Sony in order to guide con­sumers towards one that will work. This guide­line includes min­i­mum sequen­tial read speed lim­i­ta­tions, the size of the SSD, and whether it can effec­tive­ly dis­si­pate heat with a heatsink or not.

The specs can be seen below:

  • 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).
  • Length: 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).

Sony also includ­ed steps on how to install the SSD, which requires users to remove one of the PS5’s side panels.

Some brands, such as Sea­gate, have already announced exist­ing NVMe SSDs that will be com­pat­i­ble with the PS5. Sea­gate’s Fire­Cu­da M.2 dri­ves, which come in 500 GB, 1TB, 2TB, and 4TB sizes, are all com­pat­i­ble with the PS5. They are sold with and with­out heatsinks, but it’s unclear which will be a prefer­able match with the PS5. The 500 GB ver­sion with­out a heatsink starts at $140, increas­es to $240 for a 1TB mod­el, and is a whop­ping $950 for the 4TB ver­sion. Adding a heatsink does increase the price for all variations.

In today’s firmware update, Sony added a dis­claimer stat­ing it can­not ensure that dri­ves that meet the above spec­i­fi­ca­tions will work, so it might be best to wait before rush­ing out to pur­chase an NVMe SSD.

Sony recent­ly announced this week that the PS5 has sold over 10 mil­lion units world­wide since its release, mak­ing it the fastest-sell­ing PlaySta­tion con­sole ever.
