Method and computer program product and apparatus for handling garbage collection process

Abstract

The invention is related to a method, a computer program product and an apparatus for handling garbage collection (GC) process. The method, performed by a processing unit of a flash controller, includes: detecting that an portable storage device is inserted into a host equipment; obtaining a maximum transmission bandwidth of a host interface; determining that a transmission bandwidth of a flash interface is higher than the maximum transmission bandwidth of the host interface; and in response to the determination of the transmission bandwidth of the flash interface being higher than the maximum transmission bandwidth of the host interface, inserting an operation of the GC process during an execution of a host command.
