1. A computer storage system, comprising:

  • a plurality of disk drives for storing distributed parity groups, each distributed parity group comprising storage blocks, said storage blocks comprising one or more data blocks and a parity block associated with said one or more data blocks, each of said storage blocks stored on a separate disk drive such that no two storage blocks from a given parity group reside on the same disk drive;

    file system metadata to describe a location of each of said storage blocks; and

    a load-balancing module to dynamically move storage blocks of said distributed parity groups among said plurality of disk drives to balance loading of said plurality of disk drives and thereby improve throughput of said computer storage system, said load-balancing module configured to update said file system metadata when a storage block is moved.
