You may be right. My suspicion would be that a lot of the data is not terribly compressible, and that you'd be looking at over 1TB for the repository of a decent-size project. Add one checkout of head on top; add build products to that. Build products mount up surprisingly quickly, with multiple gigabytes of objects and PDBs being common. 1+TB (and git doesn't support partial checkouts) would make it difficult for people to work off a laptop, or use a SSD. Everybody would need 2 2TB drives on the off chance that they might have to work on more than one project at once. Or you'd have to check less stuff into the git repository. I know people say disk space is cheap; I just don't think it's quite cheap enough yet to piss away to this degree. It's one thing to have a server with masses of storage, I'm just not convinced you can require every client PC to have the same. I could be wrong.
