The abstract of the patent published by the U.S. Patent and Trademark Office states: “There is provided a computerized method, computerized system, a non-transitory program storage device and a computer program product for enabling allocation of segments in a RAID stripe to respective storage devices in a corresponding RAID group. A randomized distribution scheme is generated for randomly distributing the data segments and syndrome segments in a RAID stripe to respective storage devices in the RAID group. The randomized distribution scheme is used for distributing the segments in the at least one RAID stripe to the storage devices in the RAID group, such that any two failed storage devices in the RAID group would have the same first probability, (P) for being protected by the same type-1 syndrome segment and the same second probability, (1-P) for each one of the two failed storage devices being protected by a different type-1 syndrome segment, irrespective of the relative location of the two failed storage devices.
