Hard drive space went from 6.8 GB to 9.3 GB, now I’m officially ready for that 8 GB multiplayer install on launch day. It really sucks to have the ancient hard drive.
You might wanna make more room… Spartan ops is gunna be constantly coming in week after week and those downloads take some space too
the multiplayer is only 4gb 
“Halo Infinity Multiplayer
4 GB available storage space required. Minimum 8GB USB Flash Drive or Xbox 360 Hard Drive required. (For Xbox 360 4GB, Arcade and Core consoles, Xbox 360 Hard Drive sold separately.)”
at least an 8gb “Flash Drive” is required - because there is no such thing as a 4.5gb or 6gb, 8gb is the next step up, and a drive always needs some working space, so a 4gb drive isn’t enough - OR an xbox 360 hard drive (no such thing as a xbox hdd under 4gb, arcade 4gb flash memory is not a hdd)
I definitely recommend that you upgrade as soon as possible.

Well that’s a relief

But why? I could easily delete the rest of my hard drive. I became a PC gamer between when Reach was released and now, so I really don’t care about my game saves other than Halo.
Well, I think I still have about 100gbs left so I’m good.
I’ve got about 290 gb’s left so i should be good.
