I think that's true for all defrag tools now. Even spindle disks are dense and fast enough that combined with read-ahead, disk caching, SuperFetch, etc the physical location of the data on disk has very little affect on performance. I'm sure all of their technical numbers are accurate, but like any statistics they can be interpreted multiple ways and of course they're going to present them in a way that benefits them and their products. And because of the mechanisms mentioned above it's pretty much impossible to reliably benchmark the effects of defragging which works in their favor because you can't really disprove their claims.
And the SSD tools are even less reputable. I can't even imagine what an "SSD Optimization" would do besides TRIM and initiate a GC run, maybe.
