The entire libgen archive is roughly 50 terabytes (most of the books ever written). It will be a very long time before we reach that level of storage in a phone.

I'm not sure what you mean by a very long time. We have 1tb microsdxc now and it is about 1000 times the capacity of sdcards available in 2005.

What's more ... although it would be ugly and awkward, one can easily imagine that 50 micro sd cards could easily be mounted on a single USB like device that sits in your pocket and attaches to a phone. The reason it doesn't exist is primarily nobody needs it rather than "it can't be done".

About a month ago found a stack of MiniDV tapes from about 15 years ago. It was my own home videos. I wanted to preserve them, so wanted to upload them to Google Photos. It took me some looking around in eBay to find a camcorder to play these back. When it came home, I realized that I needed a FireWire 400 port to capture full resolution. So more digging around for a FireWire PCI-E card. I was finally able to transco…

And in 2 years those tapes might be the only thing you got.

Could you elaborate?

We reached an inflection 'amazing!' point when we are able to put '100 songs in your pocket'. That was really a shocking thing given the limitations of CD/Tape etc.. But the real inflection point may come when 'all relevant information in your local disk'. The tapes here in question can maybe store every book every written! We may be able to put the entirety of Wikipedia, every film, TV Show ever made, every book eve…

It's why I pirate at 720p x265, the files are tiny. I'd rather have a extremely large and varied Emby instance than 200 movies in Ultra Bluray Remux.

I remember watching the pilot episode of Star Trek (the original series) and chuckling when Spock reports that “the tapes are badly damaged” from the capsule they recovered near the barrier at the edge of the galaxy. Turns out it might not be that outdated after all.

That happens already; there were problems getting hold of https://en.wikipedia.org/wiki/Lunar_Orbiter_Image_Recovery_P... data only 20-30 years after the missions

Me wondering about those micro SD cards that can store 1Tb.

I'm more interested in the lifetime of the medium. Durable backup media for consumers is still a holy grail as I understand. M-DISC didn't hold up to their 1000 year lifetime promise. Archival-grade DVD's are also not good enough as I understand. Syylex went bankrupt. I want a consumer-grade backup medium that can provide at least a 100 years of lifetime.

That said, I was able to recover 90% of the voice recordings my father made between 1959-1963 on reel-to-reel tapes 60 years later. Tape can be very durable but what I recovered was analog voice very tolerant of errors. I'm not so sure about gigabytes snuck into an inch-square.

Maybe that he uploaded them to an unpaid service which might make a policy shift to remove the data at some unknown time in the future?

It probably references the density within the data tape world, which is significant as there could be other ways to achieve a higher total storage, but this is one of the major components here it seems

Totally! I have a friend who does sound engineering for hollywood and he has two firesafes full of HDDs, SSDs and TAPE with hundreds and hundreds of terabytes of data. I couldn't even finish the sentence "Have you tried the cl..." before he cut me off and was like: way too much data. Didnt have the heart to tell him two of those three media types need to be powered on periodically...

HDDs can't require powering all that periodically. I just found my hard drive from college, and plugging it into my computer just worked. Great finding all my old documents and music that I'd forgotten about.

If your drive uses ZFS you apparently need to power it on more regularly than that to avoid bit rot.
