What is an M.2 SSD Drive and What Dimensions Do They Come in?

Sony revealed that they are using M.2 SSD’s in their next console; the PlayStation 5. They were quite cryptic about which drives will work in their console and that they would reveal a list of compatible products.

M.2 is a form factor for Solid State Drives that’s shaped like a stick of RAM or gum. These SSDs are generally faster but more expensive than traditional, 2.5-inch SSDs. They are usually secured directly onto a motherboard via a single screw.

Mark Cerny also mentioned that the restrictions wee down to the variety of dimensions that the M.2 drives appear to come in. Below are some of the most common form factors:

  • M.2 Type-2280 (22 x 80mm)
  • M.2 Type-2230  (22 x 30mm)
  • M.2 Type-2242 (22 x 42mm)
  • M.2 Type-2260 (22 x 60mm )
  • M.2 Type-22110 (22 x 110mm) 

Larger drives over 2 Terabytes using a stacking technique in order to increase the capacity. Effectively doubling up the memory chips by stacking on top of each other.

The space within a console is going to be limited, so it is likely that Sony will chose a mid-range to smaller size as their only option. So longer and thicker SSD’s will likely be incompatible.

Sony already uses M.2 SSD’s in their VAIO laptops. These are commonly by Samsung but it all comes down to price and quality. There is a chance the PS5 may even use Toshiba or some other branded SSD’s.
