Especially for copying ISO images, add "bs=10240" to the other dd 
parameters.  I think dd goes sector by sector (bs=512) otherwise.  You 
can try different values to see if there is any appreciable difference 
on your system.  The bs parameter allows standard size abbreviations so 
the above could have been written bs=10K.
