A method of breaking a redundant array of independent disks level 1 (RAID 1 ) for preservation of data integrity is disclosed. In one embodiment, a method for breaking a RAID 1 to preserve data integrity of the RAID 1 includes breaking a redundancy of the RAID 1 when a size of data stored in the RAID 1 exceeds a storage capacity of the RAID 1, where the RAID 1 includes a first disk and a second disk mirroring the first disk. Further, the method includes writing a portion of the data exceeding the storage capacity of the RAID 1 to the second disk, and restoring the redundancy of the RAID 1 by using two additional disks implemented to the RAID 1.
