Abstract

Methods, apparatuses, systems, and/or non-transitory computer readable media for controlling Redundant Array of Inexpensive Disks (RAID) operations by a flash storage device are described. The method includes receiving Input/Output (I/O) attribute information of a RAID operation in an I/O command from a host device. Further, the I/O attribute information is stored in a RAID meta store area reserved on the flash storage device. Further, the method includes flushing the I/O attribute information along with meta data of the flash storage device in the RAID meta store area to a flash of the flash storage device on occurrence of a sudden power off. Furthermore, the method includes transferring the I/O attribute information, flushed to the flash, to the host device for performing data correction for one or more flash storage devices in the system based on the I/O attribute information received from each flash storage device.
