Just an update to an old thread to add my experiences:
I skipped 7.6 totally and reinstalled my entire operating system (Ubuntu
10.04LTS) on to a new small (but fast) SSD and installed LMS 7.7.2. All
other hardware remained untouched with music being stored on a separate
conventional HD.

Without the trick mentioned earlier in the thread, previous scan times
with SBS 7.5 were at least 10 hours, which was ridiculous, especially
if you only have a few things to add to the menus. 2.5 hours is back
in the realm of reasonable for 60k tracks.
