System and method for efficient comparison of mirrored storage devices

A non-transitory computer readable medium having stored thereon instructions for causing a processing circuitry to perform a process, the process comprising:

• selecting, from a storage slice of a first storage device and at least a second storage device, corresponding storage blocks that are not trimmed blocks, wherein trimmed blocks are blocks within a storage device marked for erasure;
• comparing the corresponding storage blocks such that a non-trimmed block of the first storage device is compared to a corresponding non-trimmed block of the second storage device to determine which storage blocks do not match;
• and
• performing a recovery operation between the non-trimmed block of the first storage device and a non-matching corresponding first non-trimmed block of the second storage device.

A system for comparing mirrored storage devices, comprising:

• a processing circuitry;
• and
• a memory, the memory containing instructions that, when executed by the processing circuitry, configure the system to:
• select, from a storage slice of a first storage device and at least a second storage device, corresponding storage blocks that are not trimmed blocks, wherein trimmed blocks are blocks within a storage device marked for erasure;
• compare the corresponding storage blocks such that a non-trimmed block of the first storage device is compared to a corresponding non-trimmed block of the second storage device to determine which storage blocks do not match;
• and
• perform a recovery operation between the non-trimmed block of the first storage device and a non-matching corresponding first non-trimmed block of the second storage device.
