It's one of things you should benchmark for the situation you're in.
I've benchmarked RAID1+0 (or 0+1) and RAID 5 on a Sun StorEdge 3510 to find
that RAID5 writes are 30% slower which is pretty consistent with what I see
in other private (and older) benchmarks. Mind you I don't use Linux-based
storage management.
