Sonys requirements are highly specific and hard to parse for those who dont know much about SSDs.

Sony published aguide to installing M.2 SSDs on PS5, but it stops short of recommending specific SSDs.

Dont worry though, weve got it covered.

What are the benefits of an internal expansion drive on PS5?

Its simple: more storage space.

The PS5 comes with just 667.2 GBs of space.

Expanding your PS5s storage with an extra SSD can add up to 4 TB of extra space.

An internal M.2 SSD is not the only way to boost your PS5s internal storage space, mind.

However, external USB devices can onlystorePS5-specific games.

An internal M.2 SSD, however, can store, play, and update all PS5 and PS4 games.

The only hard part is figuring out which SSD devices will actually work on PS5.

This info will be crucial if you decide to buy a drive that isnt on our list below.

The M.2 SSD must be PCIe Gen4 or newer.

PCIe Gen3 and older are not supported.

The storage capacity must be at least 250 GBs, and a maximum of 4 TB.

Read speeds of at least 5,500MB/s or faster is recommended.

M.2 SATA SSDs are not supported.

The PS5 supports single-sided and double-sided M.2 SSDs

Your M.2 SSD must have a heatsink.

Double-sided SSDs will need heatsinks on both sides.

That said, do not add additional heatsinks to drives that already include them.

Along with the above hardware specifications, the PS5s expansion drive slot also has strict size limits.

Width:

A 22mm-wide M.2 SSD module is required.

The total structure (including an added cooling structure) cannot exceed 25mm (0.984in).

The total size above the board must be less than 8mm (0.314in).

Weve also made sure to separate single-sided and double-sided SSDs and heatsinks into their own subsections.

At this point, theWestern Digital Black SN850is the best option.

confirm you buy the ones that already have the heatsinks attached.

They cost a bit more if they come with a pre-attached heatsink, but the convenience is worth it.

There are also many other M.2 SSDs that meet Sonys requirements on paper but havent been tested yet.
