The news was announced during today's Road to PS5 online livestream, in which the system's lead architect Mark Cerny provided a wealth of new information about the PS5 specs.
"Expandability of our [Solid State Drive] is going to be quite important," explained Cerny."Flash is costly and you may very well want to add storage to whatever we put in the console.
"The kind of storage you need depends on how you're going to use it. If you have an extensive PS4 library [...] then a large external hard drive is ideal. You can leave your games on the hard drive and play them directly from there, saving the pricier SSD storage for your PS5 titles, or you can copy the PS4 titles directly to the SSD. If your purpose in adding more storage is to play PS5 titles, though, ideally you will add to your SSD storage."
Cerny went on to stress that Sony "will be supporting certain M2 SSDs" (a.k.a. third party SSDs) to be compatible with PS5, explaining that "these are internal drives that you can get on the open market and can install on the day on the PS5."
