Ace Combat 8 Requires 125GB on an SSD
Ace Combat 8 requires 125GB of available space on an SSD. Installing the game on an HDD would not meet the published minimum specification.
What the official material confirms
“Available space” is an installation requirement, not necessarily the exact network download. Steam does not name an SSD interface, minimum read speed or the technical reason behind the requirement.
Why this matters to players
Players can plan storage without buying an NVMe drive solely from an unsupported assumption. Extra room may be useful for unpacking and updates, but no exact additional buffer is official.
What is still unconfirmed
Final download size, day-one patch size, Deluxe installed-size difference and future content storage are not known.
