METHODS AND SYSTEMS OF EFFICIENTLY STORING DATA

Abstract:

The present disclosure provides methods, systems, and non-transitory computer readable media for efficiently storing data. The methods include segmenting a parcel of data into one or more data chunks according to a physical block size of the secondary storage unit, wherein the one or more data chunks include a partial data chunk and zero or more full data chunks; sending each full data chunk of the zero or more full data chunks to the secondary storage unit to be written to a selected physical block of the secondary storage unit; collecting, in a collection buffer, the current partial data chunk and at least another partial data chunk; and sending a combination of the current partial data chunk and a subset of the plurality of other partial data chunks to the secondary storage unit to be written to a selected physical block of the secondary storage unit, wherein said combination fills substantially all of a physical-block-sized data chunk.
