Systems, methods and computer-readable memory for garbage collection in a storage device. One method comprises, upon a write of data to a first garbage collection unit (GCU) of the storage device, incrementing a number of logical mapping units stored in the first GCU along with a number of logical mapping units with valid data stored in the first GCU. A number of logical mapping units with invalid data stored in a second GCU is decremented based on the incremented number of logical mapping units with valid data stored in the first GCU. The second GCU is erased when a valid data rate of the second GCU is below a valid data rate of the first GCU.
