    Abstract: A trim management method for a storage device includes activating, by a processor configured by an application program, a pattern check function of a device driver, requesting, by the processor configured by the application program, a file system to write a file of a specified pattern, converting, by the processor configured by the file system, the file to management unit data of the storage device, transmitting, by the processor configured by the file system, the management unit data to the device driver, checking, by the processor configured by the device driver, whether a data pattern of the management unit data is the same as the specified pattern, and transmitting, by the processor configured by the device driver, a trim command for trimming a storage area corresponding to the management unit data, to the storage device based on results of the checking.

    Abstract: A storage device is configured to be connected to a host device via a physical cable which includes a power line and a data line. The storage device includes a non-volatile memory, a data path controller configured to temporarily deactivate the data line while power is supplied from the host device via the power line, and a memory controller. The memory controller includes a biometric module configured to receive biometric data and perform user authentication based on the biometric data; a biometric processing circuit configured to change a state of the memory controller, based on a result of the user authentication; and a data processing circuit configured to encrypt and decrypt data. The data path controller is configured to temporarily deactivate the data line in response to the changed state of the memory controller.
