Almost certainly, yes.

You'd have to measure it on your own workload, but I wouldn't expect any. Hardware RAID frequently offers a significant performance benefit as a result of having a battery backed write cache. As long as you don't fill the cache, writing to the RAID card's RAM is very fast, and writes will go to disk as idle time is available. Your BIOS raid probably doesn't have a write cache, and thus probably is no better than software RAID for performance.
