Of Course 3GBit is cheaper than 6GBit- 6GBit is new.

if you have so many disks I would recommend a chassis with expander
Backplane (like Supermicro 846E16). You have 4x6GBit to the backplane
which should be enough even if you connect 24 HDD.

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.
