Abstract
A storage device, a memory controller, and a data protection method are provided. The method includes when receiving a read command sent by a host, adopting a corresponding output flow rate limit to determine an operation that is executed on read data corresponding to the read command by the host according to location information included in the read command or a type of a transmission interface between the host and the storage device. The method also includes executing an interference procedure by the storage device to prevent the read data from being copied to the host or slow down the speed of copying the read data to the host when identifying that the operation is a copy operation.
