I was just curious what people's thoughts were on the potential "total system throughput" (whatever you choose it to be), wrt using software RAID. It would seem that software RAID would just kill big chunks of cache, especially CPU cache, moving lots of data throught it to calcuate CRC's. perhaps the raid 1/0's would be fine, since the calcuation could be ignored. It would seem that for file-server type tasks, where hopefully CPU is not an issue, then as long as you can exceed the capacity of your network, you're probably fine. And most workstations probably don't run 100% (modulo things like the various crackers and seti), that it's a non issue.
