Think about what USB stands for. Then reconsider whether you'll ever have the 
chance of writing truly simultaneously to several devices connected via 
USB... And then, as an extra exercise, think about why it takes so long when 
several different jobs are done in parallel, writing to devices connected via 
USB.
