The MFI driver needed to support that MegaRAID card has been around 
since FreeBSD 6.1:

The MegaRAID SAS 84* cards have worked extremely well for me in terms of 
performance and features for all the systems I've seen them installed 
in.  I'd consider it a modest upgrade from that 3ware card, speed wise.  
The main issue with the MegaRAID cards is that you will have to write a 
lot of your own custom scripts to monitor for failures using their 
painful MegaCLI utility, and under FreeBSD that also requires using 
their Linux utility via emulation:
