We're planning migration of an enterprise reporting system 
to SQL Server 2012, and my boss needs an argument to support 
installing a certain amount of disc space for ongoing 
operations.  Can someone point me to a credible argument 
for a reasonable minimum allowance of free disk space in 
addition to our actual databases?

I believe that this includes not having to shrink database 
files to let others grow, which we are doing now.

With 1 TB of nightly crushed data, indexes and t-logs, and 0.6 TB 
free, I think that we should shop for around 4 TB total space,
and, /yes/ we /could/ buy that size of hard disk for under 
US$200 but apparently it isn't that simple.  Although, obviously,
it ought to be.
