FIX:
RAID 1E, also called Hybrid or Enhanced RAID stripes the data across the disks with mirroring. In other words, it combines RAID 0 and Raid 1. It needs three or more disks. The first stripe is the data stripe, and the second stripe is the mirror (copy) of the first data stripe shifted one drive. It is called mirrored stripe also, because a complete stripe of data is mirrored to another stripe within the set of disks.
