regular disks (san) or ssds

Hi
I have been thinking of replacing our san that has 50 15k disks with either a ssd card like fusionio (http://www.fusionio.com) and ramsan (http://www.ramsan.com/) or, with 8-12 mid level ssds like intels x25-e http://www.intel.com/design/flash/nand/extreme/index.htm and use a good raid-controller in the server.
And then use mirroring along with regular backup to protect us from data loss if the single ssd card or the x25-e raid would fail.
Anyone here that have tried any of this? What are the results?

I don’t know any one implemented in production but there many tests around on this…

How about the number of transactions on the databases that are involved in Database Mirroring?
