What is something that's crazier than the wildest dreams of any ~1970s nerd, but exists today? I'll start with an easy one: (lemmy.ml)

You are 100% correct, there is no such thing as a 4TB SD card. Largest you can get is 2TB. Western Digital has shown a 4TB MicroSDUC and even 8TB SDUC card at shows and events, but I don't think it has found its way into production just yet. And with the extreme prices of flash these days, I doubt they will release it any time soon. The 4TB card would probably be $1500 - $2000 retail, who is going to buy that? And what is the use case?

The picture is some mockup someone made or maybe AI generated, but not of a real card.

It could be a real card from Temu. It's actually a 1 GB card, but it says it's 4TB.

You can actually store 4TB on most those cards (if you're ok with automated data deletion to make room)

Yep. It's a "write once, read never" storage medium.

[–] Quetzalcutlass@lemmy.world 4 points 4 days ago (1 children)

/dev/null is the ultimate storage solution. You can write infinite bytes to it and it'll never get full or wear out!

Very fast, too!

WORM/WORN, small difference, I say ship it.

This guy's got upper management written all over him.

A friend bought a USB stick that had some amazing data size for the era for a cheap price, turned out it ran some sort of zip tool interface and compressed the data

No one claimed the compression algorithm was lossless! Everything fits inside a single bit if you squint
