I remember reading a benchmark which showed that under random I/O patterns, the Linux software RAID performed better on a (from memory) 8 disks RAID5, due to better use of SCSI scatter/gather. I think this was vs. MegaRAID, but was a while ago. I've not carried out any benchmarks myself, and no idea whether this goes for SATA NCQ as well...
