Personally I wouldn't put data of any sort under C:\Program Files. It gets buried too deep, plus the whole concept of "Program Files" is lost. I prefer a structure like this:

C:\SQL Server Data
\Database1
database1.mdf
\Database2
database2.mdf

I also like keeping the mdf and ldf in the same folder.
