I found no mention of RAID1 in any of the graphs there, and the subject of RAID1 barely touched, basically describing its purely mirror topology and little else. I can't recall any graph there that described performance of anything other than single disk, RAID6, and RAID10. Do you know of, or can you provide a reference to, any way RAID1 performance can be better than single disk? -- Evolution as taught in public schools, like religion, is based on faith, not on science.
