Methods and systems for a networked system are provided. One method includes generating an object by a processor for storing a plurality of data chunks at a storage device, where the object includes a header segment and a data segment, the header segment providing a first offset address where an uncompressed data chunk is stored within the object and a second offset address of the object indicating a beginning of a compressed group having compressed data chunks and providing an indicator of a compression group size; reading the header segment by the processor to retrieve the second offset and the compressed group size in response to a first request for a data chunk within the compressed group; and decompressing the data chunk of the compressed group by the processor and providing the uncompressed data chunk for completing the first read request.
