About Secondary Storage..

Secondary storage (also known as external memory or auxiliary storage), differs from primary storage in that it is not directly accessible by the CPU. The computer usually uses its input/output channels to access secondary storage and transfers the desired data using intermediate area in primary storage. Secondary storage does not lose the data when the device is powered down—it is non-volatile.

Flash Storage

Flash memory is an electronic (i.e. no moving parts) non-volatile comnputer storage device which can be electrically erased and reprogrammed.
