Very nice question. The raw interface is implemented on some unix systemsystems(tru64,hpux,solaris) but not on linux. The raw interface,make makes transfer more fastfaster because i/o unix isI/O is skipped. The block interface(/dev/dsk/dev/dsk or /dev/disk/dev/disk) is more slowslower because useit uses the unix iI/oO system. To speedup dddd (gnu dd can) use bs=30Mbs=30M or bs=20M dependbs=20M depending on your hw. The short answer is : NO it is not implemented,at least as ifar as I know,I use. I am using linux fromsince the old times of kernel version 2.2 and have never see the rdsk dskseen rdsk used on unix.
