Good deal. Looks like this was $90 a few months ago on woot. $80 in January on Amazon and last year it was $75 on front page. Might not see that price ever again though.

Of course we'll see that price again eventually. Just maybe not within the next year or two. Memory will always trend downward, despite the AI inflation cost.

When the AI Data Center craze is over, this flash memory card will be right back to $25-$30.

It was just $65 on walmart with coupon for the SanDisk 512gb microexpress version. The samsung is not a good price.

Mobile devices will never add external storage back to their flagships because the buyers are sheeple and shareholders couldn't live with us not paying a subscription for storage.

And when will that be? They are milking EVERYTHING that memory and storage manufactures have, even gobbling up consumer hardware at a mass scale and harvesting the memory from that.

We don't have a government with any balls, they are all complicit, corrupt and here's the word for the day:
covetous - Feeling, expressing, or characterized by a strong or immoderate desire for the possessions of another.

They are hoarding memory so their data center competitors can't have it and we as consumers are catching strays, maybe I got that backwards maybe companies like Nintendont and Apple actually enjoy that they have an excuse to astronomically raise prices, they can raise prices multiple times a year. They gave us the middle finger when the stupid tariffs were declared illegal.

I'm still trying to figure out who these data centers will even serve if they push all of us common consumers out of the market with there hoarding strategies.

Though Nintendo has kept their Nintendo-branded 256gb card at $60 since the Switch launched, before the prices started going up. Nintendo would actually be hurt by these prices, as they don't make money from selling memory cards, and if people can't afford expansion storage for the Switch 2, they would buy fewer games.

That said, I agree with your sentiment and not sure why you're getting thumbed-down. The government needs to go after the memory company cartel that is artificially constraining manufacturing supply.

This is so disconnected from reality.

The memory makers have their full capacity sold out for future quarters as it is. They are not holding back capacity whatsoever. They are in fact trying to increase output and the only to do that is to build new fabs/implement new processes and equipment in existing fabs, neither of which is a fast process. New fabs also require new highly skilled workforce which is in short supply globally.

Maybe data centers will evolve into a digital leash and monitoring for the public, and feed into data aggregators like Palantir and Flock?

If they collected a sh!tload of data from our browsing history and device metadata, imagine what they're collecting now with ongoing daily chatbot interactions...
But as long as the leash is convenient, we don't consider it a leash.

Who does it serve? That part should be clear - definitely not everyday users.

Sheeple, agreed. Since COVID + toilet paper I've had a hard time understanding why people don't understand they vote with their wallet and fall into a scarcity mentality.

Often times the same people that complain don't exercise this rule. I sadly think the sheeple population has grown so large it prevents a good ole crash of markets. Sad because that is sometimes what it takes to right a market and those who are disciplined can capitalize on it.

Yeah yeah, some don't have a choice but often there is a big misconception of what a "need" is. Get out and ride a bike... And don't do it with a video camera on. It will be a freeing experience.

The government needs to stay out of the way of the Free Market. Name one thing that has gotten better, or cheaper due to government meddling.

Think for yourself
Cheaper: Steak. Cheese. Milk. Corn. Anything else with a subsidy.
Better: Water. Electricity. Plumbing. Medicine. Food Safety. Roads. Bridges. Firefighting. Basically all infrastructure that often is taken for granted.

"Apart from the sanitation, the medicine, education, the wine, public order, irrigation, roads, the fresh water system and public health, what have the Romans ever done for us?" <-- This is you.
