Can disk striping and disk mirroring be combined and used at the same time?

Yes – under what is referred to as RAID 0+1. This configuration combines disk striping (RAID 0) across 2 or more drives and simultaneously “mirrors” the data to a duplicate set of drives (as with RAID 1). This provides fault tolerance, but at a fairly high cost in terms of overhead. A RAID 0+1 volume requires a minimum of 4 hard drives.
