Look at it from the viewpoint of raid performance rather than disk performance. How can the throughput be less with more disks? So what if your bus bandwidth is saturated now? Then it will be saturated with more disks too, but the raid bandwidth should not change, it's still the saturation bandwidth. And if it's not saturated now then the raid throughput will increase assuming you can get more disks operating in parallel. I'm sure there are corner cases we can nitpick but isn't this correct in general? -- To unsubscribe from this list: send the line "unsubscribe linux-raid" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
