ssd need defrag?
That is called
Hyperfast optimization, not sure with its effectiveness.
For DK, I still like its IntelliWrite which is to write in a way that avoids creating fragmented data.
........it seems DK is more proactive after all.
IntelliWrite:

Since Diskeeper 2010's IntelliWrite feature works by inserting itself between Windows and users' write operations, I was interested in figuring out how much overhead Diskeeper added in this new, more active role. I measured the overheard by running the suite of hard drive benchmarks from Futuremark's PCMark05 both with and without IntelliWrite enabled. Over multiple runs, I found that the overhead introduced by IntelliWrite hovered around an acceptable 2 percent.
I was also interested in measuring the amount of fragmentation prevention that IntelliWrite would buy me. After casting around for a repeatable means of fragmenting my test disk, I settled on extracting all the files and folders from a Windows XP ISO image onto a defragmented test drive. I then recorded the number of low-performing fragments as reported by Diskeeper, deleted the extracted files and manually defragmented the disk. Over multiple runs, with IntelliWrite enabled and disabled, I found that my disk ended up with 87 percent fewer low-performing fragments on the IntelliWrite runs.
