Abstract: Presented herein are mass data storage networks, file system protocols, non-transitory machine readable devices, and methods for storing data blocks in mass data storage systems. Methods for storing data blocks in a file system are disclosed which include: receiving by storage controller of the data storage system a request to write a data file to a system storage module; determining whether the data file includes a sub-K data chunk that is less than approximately four kilobytes; identifying a packed block that stores a plurality of sub-K data chunks and has sufficient storage space available to store the sub-K data chunk; and placing, by the storage controller in the packed block, the sub-K data chunk and a corresponding data length and a respective offset identifying a location of the sub-K data chunk in the packed block.
