Martin Fuchs's suggestion of splitting it across
drives seems like a
reasonable suggestion. And I don't know what change logs are in NTFS,
but if they're anything like transactions I'd recommend them.
Using NTFS changelogs is a way to minimize the system load of permanently
updating the index information.
To say it in simple words: You ask the system periodicly, which files have
been changed or moved and only update the index information for this changes.
Any other files and directories remain untouched after an initial full index update.
