In the consumer market I user OCZ Vertex 2 and Crucial M4.
I had problems with OCZ, and it seems that I'm not the only one (I read 
15% returns)
I also have a M4 because I read that there were far less returns with 
them.

Impatient to read your results.
How many servers and OSD do you plan ?
Have you planned to compare with and without SSD ? I really wonder if 
it's justifed.
