Well I learned a new word for the day. Never knew (or needed to know) what came after petabyte until now. Also, I may just be reading it wrong but the article subtitle seems to state that 10 Exabytes = 1,000 Petabytes but this is incorrect. An exabyte is 10^18th power bytes and a petabyte is 10^15th power bytes. So an exabyte is 1,000 petabytes and 10EB would be 10,000 PB.
Oh and btw, couldn't help looking up what comes after exabyte... 1,000 exabytes is a Zettabyte (ZB) and 1,000 ZB is a Yottabyte. I wonder how long until Moore's law predicts my cellphone will have a Yottabyte of storage on a nanoSD card smaller than a pencil eraser.
