Theoretically, it should be more difficult because the storage cells change their state and thus have more energy and energy equals mass? Does it make sense? Does he do that?
I mean, I've really read that, but when I do, it's so small that you can hardly measure it
Or less I'm not entirely sure
Yes!

Translation with Deepl;
An interesting question came up on StackOverflow: Does a hard drive weigh more when it is full than when it is empty? Or more generally: does the weight of a hard drive change depending on how much (and what) data is stored on it?
First of all, as far as anyone in the IT industry is concerned, the answer is no. Any change in mass that would result from magnetic alignment is far too small to be measured by even the most sensitive scales in the world - we're talking about a difference of about 10 ^ -14 grams here.
Well how did I come up with that number?
Let's start from scratch. Every atom has a property called a magnetic dipole moment, which means that it behaves like a tiny bar magnet with a north and a south pole. In a ferromagnetic material, such as that used to store data in a magnetic hard drive, neighboring atoms tend to align themselves parallel to each other so that their north poles are all pointing in the same direction. This leads to the formation of magnetic domains, small groups of atoms that are all aligned; each domain acts like a tiny bar magnet. To use a simplified model, a magnetic domain with the north pole pointing towards the read head represents a set bit (1) and a group of atoms with their spins pointing away from the head represents a bit unset (0). Newer drives use GMR (giant magnetoresistance) instead, which basically changes the electrical resistance of part of the hard drive depending on whether the spins are aligned in two layers or not - but still, the data is based on the alignment of the magnets.
Magnets have different amounts of energy depending on whether they are aligned or not. According to the laws of physics, the energy is a pair of magnetic dipoles
d. H. The product of the two magnetic dipole moments times the cosine of the angle between them (which is +1 for parallel alignment or -1 for anti-parallel alignment) divided by the cube of the distance between them.
Most people know that, according to Einstein's theory of relativity, energy is equal to mass according to the equation E = mc2
Well… Technically it's more complicated than that, but this equation is good enough for us. The important point is that energy, like mass, reacts ("couples") to gravity - that is, it has weight. So we can take the energy difference between the two possible orientations of the magnets and divide it by c2 to get the equivalent mass.
Back to the numbers I mentioned earlier. Let's say a hard drive contains 10 grams of cobalt for data storage, and the dipole moment of each atom is contributed by a single free electron, meaning it equals a constant called a Bohr magneton. (I'm not making any claim that these assumptions are accurate, but they should be close to the correct order of magnitude) There would be about 1023 electrons, but in a 1TB drive these are grouped into about 1012 domains that span a total area of, say, 400 cm2, which brings the average separation distance to about a tenth of a micrometer. Assuming that each domain mainly interacts with its 4 immediate neighbors, the total energy is around -5 J if all domains are oriented in the same direction (that would be like a drive that contains only zeros), or 5 J, if the domains are not aligned. Dividing the difference by c2 gives an effective "mass" difference of about 10-14 grams. Considering that a full hard drive weighs on the order of one kilogram, we're talking about a part in 1017 (that is 1 in 100,000,000,000,000,000)! This is typical of situations where energy is treated as mass: due to the factor c2, a moderate amount of energy equals an incredibly tiny mass.
Possibly, but honestly I'm not sure
we don't know what gravity is… It may be influenced by how the memory cells are charged (so, minimal maybe? I mean, who knows that exactly?)
Under certain circumstances, the wear and tear of the memory cells, which occurs when storing and deleting, also has an influence… Perhaps something oxidizes and thus oxygen would be built into the cells, making them heavier?
So… It would be possible, just… I couldn't really prove it
ah and… With SSDs, sure, because there's a charge in the device… At first I only thought of magnetic disks
You're so smart
No, the text is copied - but from a logical point of view it is of course the case that another mass has a different weight.
My intuition would be no but in fact it would appear to be yes
