with dd, use "bs=<bignumber>" to increase the block size dd reads and writes in one go - as you quote it, dd wrote 512 bytes at a time. A good value to start with would be 1048576 (1MB). Also, you may have "stopped" the command in an unintended way - Ctl-Z doesn't terminate a command, merely "freezes" it in its tracks (technically, pressing Ctrl-Z causes the shell to send SIGSTOP to the process); you could let it resume at a later time by using either "bg" (to have it continue in the background) or "fg" (... you get the idea ;-).
