I would think software raid would be quite inappropriate considering postgres when it is working is taking a fair amount of CPU as would software RAID. Does anyone know if this is really the case ?
The common explanation is that CPUs are so fast now that it doesn't make a difference. From my experience software raid works very, very well. However I have never put
software raid on anything that is very heavily loaded. I would still use hardware raid if it is very heavily loaded. Sincerely, Joshua D.
