Abstract:
The present disclosure relates to a system and a method for data protection. In some embodiments, an exemplary method for data encoding includes: receiving a data bulk; performing an erasure coding (EC) encoding on the data bulk to generate one or more EC codewords; distributing a plurality of portions of each EC codeword of the one or more EC codewords across a plurality of solid-state drives (SSDs); performing, at each SSD of the plurality of SSDs, an error correction coding (ECC) encoding on portions of the one or more EC codewords distributed to the SSD to generate an ECC codeword; and storing, in each SSD of the plurality of SSDs, the ECC codeword.
