IMO, 3ware is far and away the best choice for true hardware SATA RAID. 
The 3w-xxxx driver (for the 8000 series boards) has been in the kernel for 
a *long* time, and 3w-9xxx driver (for the 9000 series) has been in a 
while as well.  There are some better performers out there at the moment 
(Areka, for example), but their drivers are unproven.

FWIW, I currently have 4TB (2 servers) worth of 3ware based storage in 
production, and just took delivery of a new 5.5TB server.
