    /dev/dsk-block device /dev/rdsk -raw device

    In /dev/rdsk if the data which is written did not used full 512bytes of a sector then for the next time we cannot use the left space.

    where as /dev/dsk maintains a buffer memory from where the data is copied to disk so there is no loss of space.
