I can't find a non raid SATA controller than works for me under linux. 3ware cards tend to max out a 64/33 solt around 6 drives for sequential IO. (This will change in their next gen cards) You get much better performance with two 8 port cards running 6 drives each than a single 12 port card. Personally I recommend either 3ware raid10, or linux software raid 5 if you're a performance junky. Adaptec does have a new 4 port card sata raid card. It seems to work well, and the driver on their cdrom includes around 30 precompiled binaries for various RH, MDK, and Suse kernels. Source for the updated aacraid driver is included. An interesting side note their cdrom seem to run linux. (Yes they seem to provide source/patches for the various gpl programs it uses.) -- Once you have their hardware. Never give it back.
