I just checked my audiophile installation. The BIAB files without the RealTracks and RealDrums takes up 33 GB. That includes quite a few files I happen to store there, like songs from fakebooks, that are not part of the default installation, but those files are pretty small.

On any hard drive, you need to try to keep 15% of the drive free to avoid thrashing. However, on an SSD, I believe the percentage can be much lower but I don't have a rule of thumb to cite.
