This normally performs the best out of all the options, however this depends entirely upon the controller and disks. The Adaptec SATA controllers, for example, perform worse than the 3ware controllers, which in turn perform worse than the Areca controllers. They are priced in the same order as well. You get what you pay for.
Generally if the controller has more than 4 ports and supports RAID5, it's going to be a hardware controller.

! Software RAID
Software RAID is performed in the kernel. Linux 2.6.11 has support for RAID levels 0, 1, 1+0, 4, 5 and 6. You can probably do RAID 0+1 and RAID 1+0 using the individual RAID 0 and RAID 1 modules, but there is specific support for 1+0. See SoftwareRaid for some more infomation about this under linux
