Do you know if you weigh an empty USB and a full USB, which one is heavier?

   Let's analyze the weight of the data together in the following article.

   Data on computing devices is a series of electrons, so have you ever wondered how much 'heavy' data is theoretically? If comparing a USB full of data and a USB without any data, which USB is heavier?
   The answer is that a USB that contains data is heavier than an empty USB, although in practice the difference in weight is so small that we cannot judge it, but in theory, that is completely true.
   Let's first find out how the data is stored. The data is essentially strings of 0s and 1s arranged in binary code and it is stored on some medium. For USB flash memory, the numbers 1 and 0 will be stored by 'locking' the electrons. These electrons have a mass of about 1.7×10^(-24) grams.
   The more data is stored, the more electrons are used. For every 4GB of data, the USB will weigh about 10^(-18) grams. This calculation was done by computer professor John D. Kubiatowicz at the University of California in 2011.
   And if we want the USB to weigh more than 1 gram, that USB will need to hold 4,000,000,000,000,000,000,000 GB (4 billion billion GB) of data.
