OCZ Revodrive 3 x2 and Truenas/Freenas

I had one of these drives laying around. All my SATA ports are full on my NAS, so I thought maybe I would toss this in to look at moving my jails or possibly use it as an L2arc. It is a known working drive. I tested it to be sure. When booting the NAS, it shows up to configure. But, once in the OS the drive does not show up in the drives area. I did some googling, some places say it is supported, some say it is not. Some refer to needing to load drivers manually, but nothing on how or where to get them.

I would like to get this working, if not, not a huge deal, but would be nice.
