Marvel at the blistering write speed!!

The speed is because the dd copied the data into kernel buffers and does not 
wait for those buffers to flush to the USB stick.

Seems like people didn't actually look and missed the sarcasm... 2.4 MB/s is the "blistering write speed". :-)

If you do not wait for the buffets to flished to the stick then the file system 
will be corrupted.

Tools like fedora media writer do the waiting until the data is safely on the 
stick.

dd by default waits at the end to sync the data, so often you'll get a crazy initial write speed that gradually goes down until it's finally finished.
