Abstract
Systems, methods and/or devices are used to enable garbage collection of a sub-block of an individually erasable block of a storage medium in a storage device. In one aspect, the method includes determining a first trigger parameter in accordance with one or more operating conditions of a first sub-block of an erase block in the storage medium, and determining a second trigger parameter in accordance with one or more operating conditions of a second sub-block of the erase block in the storage medium. In accordance with a determination that the first trigger parameter meets a first vulnerability criterion, garbage collection of the first sub-block is enabled. Furthermore, in accordance with a determination that the second trigger parameter meets a second vulnerability criterion, garbage collection of the second sub-block is enabled.
