AS you know I been using Diskeeper for years. The program says it has SSD support but was looking over their site a bit ago and see they have dedicated SSD program. http://www.condusiv.com/home-use/ssdkeeper/home/overview/
There's a review of it a 4sysops. But it just gives an overview of the features, rather than doing any before and after benchmarks.
This software must do things different the Diskeeper but in the documentation, it shows Diskeeper works with SSD's also. Here is a screen shot of Diskeeper. Notice how it looks a lot like SSDkeeper.
