RAIDXpert User Manual RAID 10 - Mirror/Stripe RAID 10 combines the properties of RAID 0 and RAID 1 logical drives. RAID 10 increases performance by reading and writing data in parallel while protecting data with duplication. Four physical drives are required for RAID 10. One drive pair is mirrored together then striped over a second drive pair. Figure 4. RAID 10 mirrors data over one drive pair and stripes it over the other drive pair Data Stripe Data Mirror physical drives The data capacity is similar to a RAID 1 logical drive, with half of the total storage capacity dedicated for redundancy. An added plus for using RAID 10 is that, in many situations, RAID 10 offers double fault tolerance. Double fault tolerance may allow your logical drive to continue to operate depending on which two physical drives fail. RAID 10 logical drives on the AMD Chipset SATA Controller consist of 4 physical drives only. 98
