Re: Repository over Raid?

I have a question here.... If you do a commit, the only thing that is
changing is the file that you changed for that particular revision. So
each commit is not necessarily adding another 30 GB of data. Unless you
have some wonderfully productive developers, or the individual file
sizes are monstrous, I doubt they could realistically change much more
than 100 MB of files in a single day (on good day). That's not to say
an occassional new file will be larger than that.....

But the key dispute I have is that the commit is only writing the
_CHANGED_ files and not the other 29+ GB of files that are not modified
by your developers on that day.

Food for thought.

Regards,
Frank
