<p>The present invention relates to the technical field of storage, and particularly, to a storage method and a storage system of a memory, so as to solve a problem of an increase in resource costs caused by a fact that large storage space is needed when an SLC memory stores large amount of data, and solve a problem that data loss easily occurs due to a complex structure when an MLC memory stores data having high security. The following method is used in embodiments, and the method comprises: determining to-be-migrated data in a logic block in an SLC mode, and migrating the to-be-migrated data in the logic block in the SLC mode to a logic block in an MLC mode having not stored data; and determining to-be-migrated data in an logic block in an MLC mode, and migrating the to-be-migrated data in the logic block in the MLC mode to a logic block in an SLC mode having not stored data. When stored data has a high requirement for security, the data is migrated to the logic block in the SLC mode and is stored; and when a large amount of data is stored, the data is migrated to the logic block in the MLC mode and is stored.</p> |
