does USB have same weight when its full as when its empty?

Funny yet interesting and a scientific question bro! It doesnt gain weight how much data you put on your data drive, flash disk, harddrive, diskette or whatever data storage mediums. It only have static or magnetic storage capability that can store datas. Like micro switches inside of it like a no data, 0000, and with some data, 0011FF.. I wonder if a data will gain physical weight, those smart and intelligent people will get a very heavy brain, heads and imagine it adds up in their weight per pounds!!!

A very nice discussion frankly speaking There is a negligible amount of change in mass, but the electromagnetic charge balance may be tilted and changed in order to facilitate the data storage and also the total energy stored in the drive will change. The data points and stuff will all varry. Its really tough one mate

It 'gains' virtual weight, not physical weight :P What a silly discussion!

Not a single thing. Data bits are information stored magnetically on a flash memory chip. If we consider electronic stream running on the circuit during operation, there would be an insignificant rise in the wight of the whole thing, by a factor of a few millionth of a gram (9.109 382 15(45) × .0000000000000000000000000000010 kilograms/electron x number of electron present at a given instant in the USB circuit.)

Interesting question, you got everyone thinking. A usb does not gain weight when you put data onto it. If it did a person carrying a 160Gb would be in be trouble.

I would think that the weight it gains is all virtual. That's why even if you put it on a physical scale, it wouldn't register any weight gain. Now, if you had a virtual scale... LOL!

The data in a flash memory (USB memory) is stored using electrons, but the amount of electrons needed is low even in a high capacity memory, then the gain in weight is unmeasurable since the mass of each electron is very very tiny, maybe the gain in weight of a full memory (zero filled memory) could be only a few picograms or maybe even less. Interesting question...

Instead, consider that there is some energy storage in the form of binding energy for the trapped electrons in the gates.This energy will have some equivalent mass via E = m*c^2. It'll be all but unmeasurable . ;) enjoy

lol nope, even your usb is full of data it will never gain weight ^^ nice topic ^^
