I wrote not RAID, but RAID1, very purposely. 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?
