If you want S-ATA raid, absolutely have a look at Areca controllers. We run a 24x S-ATA 250 GB disk system on Intel 7501 dual Xeon board, and had quite some trouble with the 2 3Ware 9500-12 controllers under 2.6 kernel, from lock-ups to file corruption.
Recently replaced the 3Ware controllers with 3 Areca 8 port controllers, and the server is running absolutely stable under very heavy load. And whatever anyone may say or benchmark, the Areca's are a lot faster. Subsequent bonnie++ benchmarks report over 220 MB/s write, over 280 MB/s read for a singel controller in RAID 5. Why loose half your capacity and do RAID 10 ... Never got the 3Wares in RAID 5 over 100 MB/s read write under kernel 2.6, whatever tweaking I tried. Was a lot better with 2.4 though, but no go for my system because of the kernel's 2TB limit. I plan to build a new server now, it is definitely going to be Tyan K8S + Areca controllers, probably the same 24x S-ATA system with 250 GB disks, or a 16x S-ATA system with 400 GB disks. And the exisiting server is also going to be upgraded to 64 bit.
