A particular numbered inode always lives in the same place on the disk. When choosing what inode to use for a new file, the filesystem tries to pick a inode to put the file close to the directory it is being created in. This is the dirpref optimisation introduced a few years ago - previously inodes were chosen from a part of a disk that had the most nearby free space. David.
