The later versions of Diskeeper can safely defrag SSDs.
I had once posed this question to Verbatim whose flash drive I am using. Verbatim had replied never to defrag the Flash Drive with ordinary defraggers that don't have the SSD defragging option.
Verbatim said that the SSD's life was dependent on the number of write operations performed on it and therefore there could be nothing worse than defragging it with ordinary defraggers.

I agree with this.
Though SSD users have this in mind,
dont ever defrag your ssd.
Defragmentation kills SSD.
I said that to my boss, but he didn't listen. Like... he didn't believe me. So how? Let his HDD crashes itself? xD
