Sorry, I do not have a SSD beforehand to test the HyperFast add-on but other feature like IntelliWrite and InvisiTasking work superbly that Raxco PerfectDisk 12 detects that Diskeeper Pro 2011 has optimized my harddrive peformance up to 99,99%. I do not think HyperFast will dissapoint you either as Diskeeper is world class defragmenter after all.
