Alsoft today released DiskWarrior 4.
DiskWarrior 4 maintains, repairs, and recovers Mac disks on both PowerPC and Intel-based Macs as the application is now a Universal Binary.
DiskWarrior 4 costs US$99.95 for the full version and $49.95 for the upgrade.

A tool for showing volume fragmentation is here:

I’d be interested to see what frag levels people have. Mine is currently 99.97% unfragmented.
I use iDefrag, it’s really good and well worth the money. I noticed a huge speed increase after I used it. You need another copy of OS X because it can’t defrag a boot drive.
There’s a good explanation of why you need to defrag on the site too. I defrag once every 2-3 months.
Do you have any scientific benchmarks or did your machine just “seem” faster. You shouldn’t notice any performance difference defragging a drive with less than 10% fragmentation.
DW 4 vs. TTP 4.5.2
============================
in the past, OS9 and maybe pre TTP 4.5, I would have said use DW vs. TTP, but Alsoft has been very arrogant with their very, very late release of DW4 for Intel. TTP 4.5 for Intel came out quite a while ago. Also, the lack of download to upgrade to DW 4 for registered users is a pain in the A$$. I had a problem today and used TTP 4.5.2 to fix some very serious overlapped files and extents issues, thst I used to think only DW could handle. I don’t know if I will be spending the $60 U.S. w/ delivery to get a product that does only a fraction of what TTP 4.5.2 does. Like I said I found Alsoft very arrogant about their UB re-write and had been asking them for many months about it with the stanadard reply of “real soon now” – what really pissed me off is that if you purchase the FULL DW4 you can download it, but NOT the upgrade for registered users – translation -> if you’re a customer – they don’t care. Sorry, but I’m very pi$$sed.
