Verified answer
Is an SSD officially required on PC?
Quick answer
Steam currently lists 100 GB of available storage but does not explicitly label an SSD as mandatory in the reviewed requirements.
What this means
An SSD may still improve loading or become recommended in later documentation, but the present store table does not justify rewriting “100 GB storage” into a mandatory SSD claim.
