Raid levels which have excellent i/o rate

WebSo an eight spindle RAID 10 array would be N = 8 and X = 125, and our resulting calculation comes out to be (8 * 125)/2, which is 500 WIOPS or 4X WIOPS. A 50/50 blend would result in 750 Blended IOPS (1,000 Read IOPS *.5 and 500 Write IOPS*.5.) This formula applies equally to RAID 1, RAID 10, RAID 100, and RAID 01.
