I recall watching a documentary (on Curiosity Stream maybe? I’m no longer subscribed) on data storage longevity. It covered DNA storage, which I think this PBS video w/ transcript provides more recent coverage of its developments. As well as holographic storage, which I could only find the Wikipedia page for.
As for which one I think might be the future, it’s tough to say. Tape is pretty good and cheap but slow for offline storage. Archival media will probably end up all being offline storage, although I could see a case for holographic/optical storage being near line. Future online storage will probably remain a tough pickle: cheap, plentiful, fast; select at most two, maybe.
Im most excited about the potential for crystal based storage. Right now there is work being done to etch silica glass internally, allowing for incredibly long term preservation and durability. It can even be rewritten, though the tech is definetly best for achival purposes and is being pursued primarily by movie companies wanting high quality storage.
DNA also sounds interesting, though it doesnt seem like a good way of preserving data long term. DNA is very fragile, and seems like an odd route to take for long term archiving.

Yeah the 5D quartz disk is very cool.
Anyways if you think about storage density DNA isn’t that “odd”. With DNA you can store dozens of copies of the data and parity checks in a very small space so even if some gets corrupted you can still get it. I get that organic stuff has its limits but the density is just mind blowing.
Density is defintly amazing in DNA, its just so fragile. Even our own bodies have a constant degridation of our DNA… I wonder if they could take that concept and make something sturdier by using slightly different molecules to make up the chains.
Maybe shorter chains with stronger cross bonding & a gentle method of reading the chain could also help?
Its definetly an interesting route & itll be cool to see what happens with it over the next 10-15 years.
The truth of academia is that it is extremely slow. there are less than 20 minds total on all of earth working on this idea, separately, in different countries. And these 20 people are in their 20’s, severely underpaid, don’t necessarily have all the resources they want, and science may not be their #1 life priority.
anyways:
reading and writing DNA is the main driver of evolution, and it does so because it is error prone (causing mutations). You can imagine this is bad if you want to preserve the integrity of the data.
DNA storage would be okay if you were to… say archive the entire internet for future generations, or geneology records, etc. things that do not need to be written and accessed quickly or often.
I remember there being a water based storage solution for music that was under development, though it was said to drain entire ecosystems by doing so. Sad, as it seemed promising.
It wasn’t sensible, given the short life of DNA. One of those sci-fi ideas that caught media and technophile attention, but wasn’t ever going to go anywhere.
Project Silica appears to be attempting very high density, very long life storage, though.
Can you record the sound? I’ve never heard of a power supply having any kind of noisemaker. It’s probably just electrical interference or coil whine or something, where the waveform happens to produce that periodic sound. (You might even look around and find a nearby device changing its power draw with the same periodicity.)
Haven’t been able to record it yet, but the sound only happens when the power supply is plugged into the HDD and the outlet (not one or the other), and the HDD is NOT plugged into the computer.
Plugging the HDD into the computer stops the sound. I was unplugging it from the PC to keep it offline when I didn’t need it. (After safely ejecting and waiting etc. of course)
I guess I’ll just need to unplug the power when I’m not using it, too.
No, it’s nothing to worry about, it’ll be just a handful of super cheap parts in the power supply. Essentially when the power supply converts ac to dc, it has a bunch of standard parts, and if you cheap out on them, sometimes they make high pitched noises. The noises can vary in pitch too.
My monitor status LED makes a faint beeping sound when in standby.
Also the panel makes an audible whine when the content changes to a specific amount of white.
As another user already said: Probably low quality electronics.
You say the sound comes from the power supply and the HDD is not plugged into the computer. My diagnistic: the power-supply makes a noise when it operates at very low load (almost 0mA of current), it is probaly making the cyclic noise because of some blinking LED or another very small variation of the loaf somewhere. This is a very common symptom of cheap power-supplies, but it doesn’t necessarly mean it isn’t working normally, just an annoyance.
I suppose, when you plug the HDD to the computer, it spins up and start drawing more current from the power-supply and the noise disapears. This is because the PSU has a buck-converter, the switching frequency increase proportionally with the current drawn by the load. When the current it almost 0mA, the switching frequency can be audible (electromagnetic forces can make some components vibrate, e.g: coils). When the current is nominal, the frequency will be ultrasound and you won’t hear it. I have observed this with many electronic devices. If you are worried, you can try another power-supply, after checking it has the same voltage and polarity on the plug, and can deliver at least as much current as the original one.
I’ve come across it once with a laptop power supply. I believe it correlated to a voltage issue of some sort. We just replaced it with a new one and the problems disappeared. It definitely wasn’t coil whine, but I didn’t believe the person complaining about it until I held it up to my head myself.
