That will give you less accurate numbers, if you're looking for numbers that reflect real world performance. Again, in general, most real world writes are not stripe aligned, and not full width, especially with the insanely large 512KB chunk size. For all but a few workloads, storage should be designed and optimized assuming most writes will be unaligned or not full width, -not- assuming most will be full stripe writes. -- Stan -- 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
