Did you get this resolved? If not then you should check with LSI to make sure they support the 520 on that controller (it should work, but it's not a given). You should also check with them to make sure your HDD will still boot once you take it out of RAID mode. Once it's out of RAID mode you should be able to migrate it to the SSD.
you can try any of the following free cloning tools, since this could be related to a limitation at the software and the cloning technology is not a proprietary technology so any other cloning tool might help here some examples:
EaseUS Todo Backup,EZ Gig IV, HDClone 4, Clonezilla.http://clonezilla.org/clonezilla-live.php
You can use any other cloning software of your preference as well.
