eli5 How does computer data add mass?

242 views

Apparently adding computer data to a drive adds a tiny amount of mass to the drive but I don’t understand how, since surely the number of 0 and 1 changing shouldn’t change the mass of the media.

The memory is stored as bits, 1 and 0’s, and they are in tiny microscopic transistors.
When a transistor is charged up, it switches on, and when it is discharged, it switches off.
The computer will check these transistors, and see what happens.

Something curious is that a for a lot of memory chips, the default state is FF, or a “1”, so there’s a chance some people did look into computers, realised that the memory switches are electrical, and the electrons have a mass, but they might not have considered that blank is often 11111111111 and not 0000000000. That would mean the blank state is technically the heaviest, and the more data you add, the lighter it gets.

Some computer science people might know more about SSD and RAM type default blank memory states.
