1. The SSDs we develop will last up to 20 years even if you write more than 20GB of information a day (which is well beyond the normal user). I believe you will replace your system long before you replace the SSD.
2. The defrag does not damage the drive but will put onto the drive a very large number of writes and re-writes so your drive will start to slow down faster than those drives you do not defrag.
3. Windows 7 TRIM is meant to pro-actively delete corrupt or obsolete data on the SSD, and is set to run by default. However, it only works on single disk installations, and even though running in Windows, is not necessarily being implemented on the hard drive. For TRIM to function, the operating system, storage drivers and solid-state drive must all support the TRIM command.
The second part of their statement in point two, implies that SSDs do slow down over time.
The question I really want to ask you is if you have any first hand knowledge of the validity of the tests done by Diskeeper/Hyperfast or is there a better program?
Thank you in anticipation.

The trouble is that some defragmenters use the term 'Optimize' in lieu of Defragment (Raxco PerfectDisk for one) so one could easily be confused and suffer from the problem mentioned in #2 unless one is diligent.
However Raxco PD does say in the Help section:
With Diskeeper it appears that it automatically selects the right process rather than you having to select it manually, correct? From the help section:Solid State Drives are not affected by file fragmentation like traditional electromechanical disk drives. However, free space consolidation can improve SSD write performance. The SSD Optimize defrag method is a special defrag method for SSD drives that focuses on free space consolidation without defragmentation of files. As such, it will leave files in a fragmented state while consolidating free space into large pieces.
Also known as SSD, a data storage device that uses solid state memory instead of spinning magnetic platters to store data. Although it is quite different in its physical nature from a hard disk drive, a solid state drive simply appears to users, most applications, and the operating system as another disk drive on the computer. However, due to the physical differences between solid state memory and a spinning magnetic platter, the specialized techniques used by Diskeeper (and HyperFast) to achieve maximum performance from SSD devices differ from those used on typical hard disk drives.
However, the thing I would really like to know is whether the benchmark results claimed by Diskeeper for Hyperfast have been validated by third party testing? And how big an issue is fragmented free space anyway? Diskeeper's results seeem to indicate it is significant. I've Googled it but can't seem to get any definitive answer.
Have you used Raxco PerfectDisk first hand, and if yes, did it seem to make a noticeable difference?
I don't have an SSD to test it on unfortunately but I do use it. I'm usually a Diskeeper Pro fan but tried PD on my Vista OS and find it OK if not rather slow and often the UI seems to seize up. All things considered I prefer Diskeeper I think. Plus if and when I get an SSD I will obviously choose DK as it auto-selects the right method whereas PD you have to select it.
DK isn't perfect either, mine insists I have Volume Shadow Copy (System Restore) turned on, on my external hard drive, which I do not. But other than that small quirk it performs faster than PD and with no UI issues.
Now for the last question, which relates to my personal economic status, and is probably expecting far too much, but is there a freeware version of Diskeeper? lol!
Also, I think your earlier comment is valid and that the correct terminology for SSDs should be something like optimizing or consolidating random free space, so as not to confuse with normal understanding of defrag.
One of the things that always concerns me with third party software, and even Windows TRIM, which proactively delete corrupt or obsolete data is that they sometimes delete stuff that you don't want deleted, or they mistake as obsolete. More so 3rd party than Windows.
Only a 30-day free trial. The built-in Defragger in Windows is actually a form of 'Diskeeper Lite' (very Lite!) for want of a better description. There are other free defraggers out there though and there is a Diskeeper Lite version for download: Download Diskeeper Lite free .
Never tried it though so not too sure of its features.
