Dynamic Data Block Grouping Based On Garbage Collection Performance Parameters

A method comprising:

• determining, by a storage system controller, a group size for grouping a plurality of data blocks stored on the plurality of storage devices, the group size based on one or more garbage collection performance parameters;
• grouping the plurality of data blocks into a plurality of groups having the determined group size based on corresponding lifespans associated with the plurality of data blocks;
• and
• selecting one or more of the plurality of groups for garbage collection.

A non-transitory computer readable storage medium storing instructions that, when executed, cause a storage system controller to:

• determine a group size for grouping a plurality of data blocks stored on the plurality of storage devices, the group size based on one or more garbage collection performance parameters;
• group the plurality of data blocks into a plurality of groups having the determined group size based on corresponding lifespans associated with the plurality of data blocks;
• and
• select one or more of the plurality of groups for garbage collection.
