I've done it and noted no difference. However my regular drives are pretty fast anyway. In theory running on an SSD "should" at least speed up noticeably the initial loading of the program and zoning but like I said I didn't really see a difference. There must be other variables involved, such as your Internet speed. I'm on a gig-speed FIOS connection so if the disk access speed made a difference I should have noticed it.
That's MY experience at least. For me what's annoying slow is the initial log-in. Zoning is OK.
