Systems, methods, and devices for data recovery using parity space as recovery space

A system comprising:

• a controller;
• a first storage device;
• and
• a second storage device;
• wherein the first storage device is capable of operating in a fault resilient mode comprising a modified access mode with at least partial read capability based on a fault condition of the first storage device;
• wherein the second storage device comprises a parity space and a data space;
• and
• wherein the controller is configured to:
• operate the first storage device and the second storage device as a redundant array group configured to use parity information to recover information from a faulty storage device;
• store first data at the first storage device;
• store second data at the second storage device;
• and
• copy at least a portion of the first data from the first storage device to the parity space of the second storage device.

A storage array controller comprising a processor configured to:

• operate a first storage device, and a second storage device as a redundant array of independent storage devices (RAID) group with parity, wherein the second storage device comprises a parity space and a data space;
• store first data at the first storage device;
• store second data at the second storage device;
• operate the first storage device in a fault resilient mode comprising a modified access mode with at least partial read capability based on a fault condition of the first storage device;
• and
• copy at least a portion of the first data from the first storage device to the parity space of the second storage device.
