REAL WORLD Although it’s true that the upfront costs for mirroring should be less than the upfront costs for disk striping with parity, the actual cost per gigabyte might be higher with disk mirroring. With disk mirroring, you have an overhead of 50 percent. For example, if you mirror two 750-gigabyte (GB) drives (a total storage space of 1500 GB), the usable space is only 750 GB. With disk striping with parity, on though, you have an overhead of around 33 percent. For example, if you create a RAID-5 set by using three 500-GB drives (a total storage space of 1500 GB), the usable space (with one-third lost for overhead) is 1,000 GB.. 1.If necessary, connect to a remote computer.
