That image has gotta be fake, right?
SDHC only goes up to 32GB and I'm pretty sure the successor SDXC only goes up to 2TB
I'm not quite sure how a card can be both U1 and U3 too
SD express should be able to surpass 2TB, but I don't know if 4TB micro SD express cards have been made yet
They can print whatever size they want on it if youβre buying from AliExpress π€ͺ
Back in early days of Aliexpress, I was looking at a bike frame by Trek. I messaged the shop and ask if they stock Specialized as well. Shop replied βYes, of course we can put whatever decals you want on itβ.
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.
/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
SDUC can get up to 128TB btw
Has an SD card with 4tb ever been produced? Idk and i doubt
I'd say so, afaik they only go as small as a CF in 4TB.
