Systems and Methods for Performing Variable Flash Wear Leveling

A storage system comprising:

• a non-volatile memory;
• and
• a processor in communication with the non-volatile memory, the processor configured to:
• partition a memory block of the non-volatile memory into at least a first partition and a second partition;
• utilize the first partition of the memory block to store data blocks until the first partition reaches a first end of life condition;
• after the first partition reaches the first end of life condition:
• utilize the first partition for storage of data blocks associated with a compression ratio that is less than a compression threshold until the first partition reaches a second end of life condition;
• and
• utilize the second partition for the storage of data blocks until the second partition reaches the first end of life condition.

A method for performing wear leveling, the method comprising:

• associating a first memory block of a storage device with a first compression threshold;
• associating a second memory block of the storage device with a second compression threshold, wherein the second compression threshold is less than the first compression threshold;
• receiving a request to store data blocks in the storage device;
• determining a compression ratio associated with the data blocks;
• and
• determining whether to store the data blocks in the first memory block or the second memory block based on the compression ratio associated with the data blocks and the first and second compression thresholds.
