Solid state drive array performance and reliability

A computer program product for re-distributing high usage parity data in a RAID solid state drive array, the computer program product comprising:

• one or more computer-readable storage devices and program instructions stored on at least one of the one or more tangible storage devices, the program instructions comprising:
• program instructions to collect wear life data of a first and a second solid state drive, wherein each solid state drive includes at least one stride, and wherein wear life data is data which includes information regarding wear and deterioration of each stride of each solid state drive;
• based on the collected wear life data, program instructions to determine the first solid state drive contains more high usage strides than the second solid state drive, wherein a high usage stride is a stride containing high usage data;
• and
• program instructions to re-allocate data from at least one high usage stride of the first solid state drive to a stride of the second solid state drive, wherein the re-allocated data includes parity data.

A computer system for re-distributing high usage parity data in a RAID solid state drive array, the computer system comprising:

• one or more processors, one or more computer-readable memories, one or more computer-readable tangible storage devices, and program instructions stored on at least one of the one or more storage devices for execution by at least one of the one or more processors via at least one of the one or more memories, the program instructions comprising:
• program instructions to collect wear life data of a first and a second solid state drive, wherein each solid state drive includes at least one stride, and wherein wear life data is data which includes information regarding wear and deterioration of each stride of each solid state drive;
• based on the collected wear life data, program instructions to determine the first solid state drive contains more high usage strides than the second solid state drive, wherein a high usage stride is a stride containing high usage data;
• and
• program instructions to re-allocate data from at least one high usage stride of the first solid state drive to a stride of the second solid state drive, wherein the re-allocated data includes parity data.
