Abstract: 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.

Abstract: Disclosed is a storage system which includes a random access memory, storage devices, and a processing unit that controls the random access memory and the storage devices. Each of the plurality of storage devices includes a first storage area and a second storage area. The processing unit assigns a zone to the first storage areas of the storage devices. The processing unit assigns RAID stripes to the zone, performs a write of sequential data, which are based on sequential logical addresses, with respect to each of the RAID stripes, and performs a write of a parity corresponding to the write of the sequential data after the write of the sequential data is completed. The processing unit writes an intermediate parity corresponding to the parity in the second storage area of at least one storage device among the storage devices while performing the write of the sequential data.
