Quite a lot. But you might still want to bump -i when you newfs (unless you actually need all those inodes). Default is based on the frag size, but there's a limit to frag size, so it stops scaling back the inode count after a point, and lots of inodes can really slow down fsck. If the majority of your files are "media" you might want to increase it a bit, if you're keeping large backups you might want to increase it a lot.
