Abstract
Aspects of the invention include receiving data that includes a group of n symbols to be written to a plurality of storage units. The group of symbols is mapped into a codeword of n+k symbols, each assigned to one of the storage units. The codeword is configured to allow at least one of the n symbols to be reconstructed using a subset of the n+k symbols. At least one of the n+k symbols is assigned to one of the storage units based at least in part on content of the at least one of the n+k symbols. Writing each of the n+k symbols to its assigned storage unit in the plurality of storage units is initiated. The writing includes optimizing storage capacity of the assigned storage unit based at least in part on determining that the symbol has the same content as another symbol previously stored in the storage unit.
