Abstract: A storage system includes a storage device and a managing device. The managing device receives a data write request, determines a data category of a to-be-written data page, designates different logical blocks for to-be-written data pages of different data categories, and sends a data write instruction to the storage device, where the data write instruction carries to-be-written data pages corresponding to at least one designated logical block. The storage device is configured to receive the data write instruction, and write the to-be-written data page corresponding to the at least one designated logical block to a physical block corresponding to the at least one designated logical block, where to-be-written data pages written to each physical block are corresponding to a same logical block.
