Of Course 3GBit is cheaper than 6GBit- 6GBit is new. > If you build machines with 24, 36 or even more disks, this > can become quite an issue. if you have so many disks I would recommend a chassis with expander Backplane (like Supermicro 846E16).

LSI 3081E-R can also do integrated raid as well- 3801E with external connectors can't do this because of the missing NVRAM Chip. IMHO integrated raid it is supported in FreeBSD.
