Abstract
Described is a redundant array of inexpensive disks (RAID) scheme that manages the wear of individual drives in a RAID set and significantly reduces the probability of more than two drives wearing out at the same time. In one aspect, describe is a method in which at least one of a first and second of the plurality of at least three low endurance flash based solid state devices perform a predetermined percentage of more writes as compared to at least a third of the plurality of at least three low endurance flash based solid state devices. In another aspect, a rebuild operation is performed using Galois Field Multiplication, with one of an integrated circuit and a field programmable gate array (FPGA) being used in preferred implementations.
