I really don't know what Windows 2008 or more h/w would bring to the table,
but for the file system performance itself, it might be worth running a
defrag -- at least the analysis portion -- to see what the file system and
MFT fragmentation looks like. Advanced defrag tools can also defrag the
MFT, that might help speed up performance (by how much, I couldn't say...
75 million files is a lot no matter how you slice it).
