Ah! Very interesting point.. the extra inode metadata! I didn't even consider that waste.. This is something that could indeed ammount to something with that many data chunks!

Some of it could be useful, mtime, atime, ctime- could have use.. indeed, for trash collection and update purposes- possibly.

I have 3 million files because I'm tracking documents in an office environment- for a buncha users who do bureaucratic work fo tha man. So.. there are a lot of freaking pdfs, docs, "excel spreddshits", hard copy doc scans... etc. A lot.

I'm indexing everything about everything, runnig ocr and deet on every speck of junk here... Makes evyerbody's life easier and way more interesting.
