If you put data onto a hard drive, would it gain mass and if so, could you quantify how much how much a bit of memory weighs?

1kg of DNA can store all the world's data. That's the future

*unzips your dna*

What you do?

DNA rots like everything biological and its copy rate is slow.

No, it doesn't gain mass.

Magnetic memory doesn't change mass because the data is encoded as an organization of magnetic particles.
Flash memories gain mass when you write 1s to them, as data is stored by adding and removing charge particles in the data cells. The difference in mass between an all 0 and all 1 drive is essentially unmeasurable though

No honey it's not what it looks like. That porn on my DNA storage device is just a random mutation.

accidentally.
over time.
with a massive failure to success ratio.

Sounds like modern storage in general. Read failures are expected, so data is stored with forward error correction codes so bits can be recovered. DNA storage might need stronger ECC to be highly reliable, but the data density is so absurd the overhead is acceptable.

Perform methylation?

>> No.9298277

yes.
a few electrons' mass

>> No.9298283

>>9297376
for a solid state drive:
1 bit weighs the mass of the number of electrons within the volume of metal at c coulombs. We can find this using avagadros number, the desnity of said metal, the charge of the metal etc.

Hard Drive:
the disk is altered by lasers, i don't remember how so your guess is as good at mine.
