Abstract
A method for writing multiple copies into a storage device includes receiving a first write data request that includes an identity (ID) of a first logical storage unit, target data, and a logical block address (LBA) of the first logical storage unit, determining that data stored in storage space corresponding to the LBA of the first logical storage unit is not accessed by another data access request, writing the target data into the storage space corresponding to the LBA of the first logical storage unit, generating a second write data request that includes an ID of a second logical storage unit, the target data, and an LBA of the second logical storage unit, and writing the target data into storage space corresponding to the LBA of the second logical storage unit.
