Default Is an Intel motherboard RAID better or worse than software RAID?

Hi guys,

I've had some experience in the past with software (BIOS) RAID.
Obviously there would be a big performance difference with hardware vs
BIOS RAID. Has anyone done any benchmarks to the effect of BIOS vs
linux kernel RAID?
