Linux software raid will do read balancing so you may get better
performance and you can easily get more than twice with some loads. In most
setups the PCI bus is the blocker for everything that isnt limited by seek
rate.
I agree that in certain situations you may get better twice the performance
may have to do more seeking than two separate drives but on a benchmark test
like bonnie++ the average is not going to be twice a single drive. And he was
talking about benchmarks.
