sdd is a replacement for a program called 'dd'. sdd is much faster than dd in cases where input block size (ibs) is not equal to the output block size (obs). Statistics are more easily understood than those from 'dd'. Timing available, -time option will print transfer speed Timing & Statistics available at any time with SIGQUIT (^\) Can seek on input and output Fast null input Fast null output. Support for the RMT (Remote Tape Server) protocol makes remote I/O fast and easy.
