STORAGE SYSTEM WITH BAD BLOCKS, AND OPERATING METHOD THEREOF

The present disclosure provides methods and apparatuses for a storage system. In some embodiments, a storage system includes a plurality of storage devices and a host device. Each storage device of the plurality of storage devices includes a plurality of blocks classified into first type blocks, second type blocks, and third type blocks, and is configured to generate internal state information items indicating information on a first number of first type blocks, a second number of second type blocks, and a third number of third type blocks. The host device is configured to receive, from the plurality of storage devices, the internal state information items, generate target state information such that the plurality of storage devices include a same number or substantially same number of first type blocks, based on the internal state information items, and transmit, to the plurality of storage devices, the target state information.
