Take that one step further ... hardware mirroring has become quite cost
effective today and the performance has become much better. You need to
answer the question as to whether or not the CPU and the IO paths have
the bandwidth to support software mirroring. If not, absolutely don't
consider it. IMHO, hardware mirroring is the way to go.
