Abstract: A storage system and a method thereof. The storage system comprises first and second storage devices, first and second analog front ends, and a controller. The first and second analog front ends, coupled to the first and second storage devices, receive first and second analog data from the first and second drive devices for conversion to first and second digital data. The controller, coupled to the first and second analog front ends, comprises a signal processor and a common memory. The signal processor receives the first and second digital data to perform first and second digital signal processing and access the common memory. The common memory is coupled to the signal processor to be accessed thereby.
