CVS to Subversion Conversion: Diskspace Issue

Our current CVS repository has 42Gb of space. Truthfully, we'll probably not convert a lot of the stuff in there. However, let's assume we do and we keep the full history.

What would be the amount of space a Subversion repository would take up? I don't need an exact size -- just a ballpark figure.

For example, I believe that Subversion may take up a bit more space with text, but saves space with binaries. In the end, a Subversion version of this repository might take up (at a maximum) 60Gb开发者_运维技巧 of space, and not like 200Gb of space.

I'm doing an estimate for our new revision control system, and want to make sure I'm in the right ballpark. I'm thinking of requesting 200Gb of space. It's something I can get without too much trouble, but still provides more than enough room to grow. Since this will be its own system, there will be some OS files in this space.

Conversion is finished. Subversion repositories appear to be about 10% bigger. We have plenty of space.
