  1. You don’t need to defrag. After 18 months of intensive use I checked out my drive with a fragment inspector just out of curiosity. It compared favourably with my ext3 Linux partitions at under 6% fragmentation. That’s on a disk with less than 10% free space.

  2. I believe OS X auto-defrags small files. Larger files it doesn’t. There is debate about whether defragging all the files on your system has any value. However, it is possible for a drive to become highly fragmented; I’ve had “severe” fragmentation on my drives. Again, I don’t know how bad “severe” fragmentation is as far as speed and wear-and-tear on the drive.

  3. To add to DistantThunder’s comments, those that do video editing on their systems may work with many huge files that are 12 GBs or more. One hour of DV video takes about 12 GB and some HD formats can use 48 GBs or more per hour.
