> In this framework, it is shown that the mass of a bit of information at room temperature (300K) is 3.19 × 10-38 Kg. To test the hypothesis we propose here an experiment, predicting that the mass of a data storage device would increase by a small amount when is full of digital information relative to its mass in erased state. For 1Tb device the estimated mass change is 2.5 × 10-25 Kg.

...

> In what follows, we propose a simple experiment capable of testing this theory by physically measuring the mass of digital information. This consists of an ultra accurate mass measurement of a digital data storage device, when all its memory bits are in fully erased state. This is then followed by the operation of recording digital data on all of its memory bits until is at full capacity, followed by another accurate mass measurement. If the proposed mass – energy – information equivalence principle is correct, then the data storage device should be heavier when information is stored on it than when it is in fully erased state.

Interesting!

But 2.5 × 10-25 Kg is literally the weight of a single atom, which is too small a difference to measure in bulk. https://en.wikipedia.org/wiki/Orders_of_magnitude_(mass)#The...
