> at least do RAID-5 ... RAID-0 is not viable for mission-critical anything
I think the authors mentioned that their goal was to measure scaling and the maximum throughput that could be obtained from this combination of hardware, with the expectation that other, more resilient RAID modes would come in lower on those same measures.
Another comparison I would like to see, done right, is to compare a "real RAID card" with dedicated IOP, on the one hand, and a "cheap RAID card" that relies on unused cores in a quad-core CPU.
Remember, the Sandy Bridge CPUs now have 4 cores + hyperthreading! Surely, some of that 8-thread goodness can be harnessed to handle the work that a more expensive RAID controller would normally do.
How many enthusiasts and builders can keep "CPU Usage" of all 8 threads above 90% in normal production environments? (Cf. Windows Task Manager)
Your thoughts?
