Most current SATA cards aren't faster than 64/66. Heck many are
32/66, or 64/33. The problem is most everyone other than 3ware's linux
drivers suck. 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.)
