Abstract
A method and system for retrieving at least a portion of a first data file are provided. The method includes receiving a request for the at least a portion of the first data file, the request including a start of the at least a portion and a size of the at least a portion; computing a data offset that is aligned to an integer multiple of a block size of the storage device and nearest to the start of the at least a portion; computing a byte-range that is an integer multiple of the block size of the storage device; reading data within the byte-range; and transmitting the at least a portion starting at an offset relative to the data offset that is aligned to an integer multiple of the block size of the storage device.
