What is the NTFS Filesystem Fragmentation like?

I have seen thrashing with as little as 5% fragmentation. I run Norton Speeddisk Scheduled EVERY NIGHT.

The Windows Defragmentor works like CRAP. Pickup Norton SystemsWorks at a Local Computer Show from a Software "Vendor", Install it and Defrag it everynight. Tell it to defrag anyway no matter HOW "good" it says it is. I am running a 200G Drive right now... about 70% full... It took almost 3 days for it to optimize it the first time. Now it takes about 20 minutes... at 3AM ;)

As for "Klez" that'd be the Klez Virus.
