There is provided a system capable of transformation of logical data objects for storage and method of operating thereof. The method comprises: a) identifying among a plurality of requests addressed to the storage device two or more “write” requests addressed to the same logical data object; b) deriving data chunks corresponding to identified “write” requests and transforming the derived data chunks; c) grouping the transformed data chunks in accordance with the order the requests have been received and in accordance with a predefined criteria; d) generating a grouped “write” request to the storage device; and e) providing mapping in a manner facilitating one-to-one relationship between the data in the obtained data chunks and the data to be read from the transformed logical object. The method further comprises obtaining an acknowledging response from the storage device; multiplying the obtained acknowledging response, and sending respective acknowledgements to each source which initiated respective “write” request.
