I have a small problem in use of dd, actually I read this topic: How to create a bootable Ubuntu USB flash drive from terminal? and I cannot understand some things,Now my question is: whats the meaning of "bs=X" and "&& synce" in dd?

From man dd, with many more options avalable:

bs=BYTES

         read and write up to BYTES bytes at a time

You'd usually use Mega Bytes, for example bs=4M or bs=4096.

&& sync is there to flush buffers after dd is finished.
