Unironically a good idea. I can see these really helping to increase the chances of memory survival in camera applications where the camera has a high chance of being physically destroyed. Also a metal body reallllly helps conduct heat out of the flash, which will increase their lifespan in continuous-write applications.
Stainless is extra bad at conducting heat considering it’s a metal, but it’s still way better than plastic. I hope they make an aluminum version at some point.
Yes, stainless is “bad”, compared to other metals. But like you also mentioned, it’s loads better than plastic.
I’d doubt they make an aluminum one, it’s probably not worth the tooling.
When dealing with only 100-200mW, even a small change in thermal conductivity will make a big difference.
One day the card will be conductive enough for us to complain it’s hot when we take it out
Elemental silver SD card casing for maximum thermal transfer, when???
When somebody finds a better source of silver than the mines on Earth and is able to increase silver supply by several orders of magnitude.
What an age we live in
Seriously, my plastic cookware is terrible
But there’s no better way to make a really traditional dioxin omelette.
How strong is aluminium compared to steel again? Oh right, its butter…

Personally, id choose them over plastic ones if not just to save plastic
doesn’t metal manufacturing use quite a lot more energy?
But it has the benefit of not breaking down into micro plastics and getting into every part of everyone.
“Honey, I accidently digested our SD card again”
True enough. Though I wonder, as a thought experiment, what would be the actual better option in the long run. Some type of resin maybe?
Uranium
that’s…
I somehow doubt that.

I guess using renewables for the energy needs of metal production would work too
Good thing heavy metal toxicity isn’t a problem.
Steel or stainless ain’t gonna give you metal poisoning
Stainless steel leaches nickel and chromium.
Better toss all your cookware then
probably, but then i can ingest less micro plastics. Which is probably good.
You’re not supposed to eat them.
i literally cannot help myself.
But what about ingesting micrometals
do micro metals even exist in substantial capacity? The problem with micro plastics is that they don’t break down and decay until like a gazillion years later, so whatever micro plastics are in your kidneys now, will continue to be in them until you die.
at least its not a single use product, the packaging it comes in is probably a worse contributor
honestly, this might be true. There are definitely worse things to be made from metal lol
Maybe extreme weather conditions for trail cams? That’s the only reason I would think about using one but never actually buy one for lol.

People will pay more money for premium.
But yeah environmentally this is a damn good idea. We should make everything out of metal.

Cause it’s metal.
\m/
Less plastic being manufactured? Sounds good to me. :)
Seriously. Let’s light a fire under this trend. I will spend twice as much on a thing if it’s metal instead of plastic.
Likely far more energy and pollution needed to manufacture this though so overall a loss for the earth.
But most steel is recycled and most plastic is not.
You still need a lot of energy to recycle steel. Less than mining by far but still a lot.
In a sustainable world, energy can and should be cheaper than raw materials. We are only harvesting a tiny fraction of the solar energy hitting the earth, to say nothing of wind and geothermal power. Rolling out more renewables and energy storage and using some of the surplus power to switch from extracting new resources to recycling our waste would greatly lower our footprint.
But compared to plastic from virgin fossil fuels?
We as a society are going to need memory cards.
What do you think they should be made out of?
Need to be examined on e case by case basis but plastic often comes out aheadi
If you penny pinch and don’t want to pay the environmental cost, sure plastic might come out cheaper.
But when you take into account the triple bottom line, plastic comes out behind.
Plastic in a landfill is a lot less harmful than co2 in the atmosphere.
chitin
Sorry, that’s not Kosher.
Is anyone going to bother recycling the one gram of metal in this card though?
Energy needs can be met and shouldn’t be an argument for using plastic.
The pollution could be more dependending on how you look at that statement, but making something without plastic results in less plastic pollution and you can’t claim that to be an overall loss for the earth.
I respect the sentiment, but is the amount of plastic in an SD card really that significant? There’s probably more in just the packaging alone.
A journey of a thousand miles begins with a single step.
This is more like taking the first step, getting distracted by a cool bug, finding an interesting stick, and going home to show Mum your cool stick.
An SD card lasts for years, and the amount of plastic in one is negligible. It’s just not an issue.
Any reduction in plastic is a good thing.
Very nuanced view of the world you have.
An SD card lasts for years, and the amount of plastic in one is negligible. It’s just not an issue.
Hark! The ghosts of countless generations of short-sighted polluters cry out in complacent, rationalizing unison!
It’s not about expecting one model of memory card to save the Earth. It’s about moving away from needless production of toxic materials, everywhere.
And if you don’t care, nobody’s going to force you to read The Lorax, but please don’t go around shitting on people’s appreciation for even the small things.
Worrying about the plastic in an SD card just feels like bike-shedding to me, but keep up the good fight, I guess.
Yeah it’s the equivalent of finding two dollars on the ground and getting excited because at this rate you’ll be a billionaire soon enough. There’s less than 2g of plastic in an SD card - the buttons on your shirt probably weigh more.
Should have used glorious Nippon steel, folded over 1000 times.
Easy there Weeby McWeebson.
I feel like dealing with SD cards’ inevitable demise is more important than armoring them. What good is a stainless SD card that no longer functions after 2 years of use?
Well considering that most of the SD cards I’ve had always died from foul play or physical destruction of some kind I think that armoring them is not without merit.
Obviously like all solid state media they do wear out over time, and their wear leveling isn’t as good as an SSD which has a much more sophisticated controller with much more sophisticated wear leveling management.
All the comments are fun and games but they could’ve used aluminium which is way cheaper. It’s nothing more than a marketing gimmick.
Was about to say
- cheaper
- lighter
- non-conductive
- softer, won’t wear the port
How is aluminum non-conductive? It’s literally used as a lighter and cheaper alternative to copper in wires
to my knowledge, the only place they use aluminum as a conductor is in overhead external transmission lines, because you can wrap them around a steel or fiberglass/carbon fiber core (due to the skin effect this incurs minimal losses) while increasing strength and reducing weight (with the composites at least)
the secondary reason is because you can just use more aluminum, since it’s not nearly as dense as copper, and also allows you to string farther, since again, not nearly as dense.
most aluminum wiring is actually cladded in copper, it’s called CCA for what should be fairly obvious reasons.
Also i believe the oxide coating of aluminum isn’t conductive? The bare material itself is, but once it oxidizes it’s probably not a good conductor, this is why we use shit like gold plated contacts. Copper also oxidizes as well, but it’s not nearly as bad.
Aluminium is a better conductor than copper by weight, but not cross sectional area. It’s used in aerial conductors because the weight is more important than the diameter. And it’s cheaper.
it’s technically like four different reasons.
The big one is weight per foot of current carrying capacity. this reduces the amount of transmission towers you need, reducing the amount of labor, and raw materials. the aluminum itself is cheaper, but that’s a secondary effect. Since it’s not as heavy per unit, you can make the runs much cheaper. And since you can make them cheaper, you can carry more current by simply making them bigger, or adding more of them.
compounding effects are something funky.
it’s called CCA for what should be fairly obvious reasons.
CCA Ethernet cables are literally the worst. The wires are much more brittle so it’s much easier to break the cable just by bending it a little bit, and since the resistance is significantly higher, they can’t go as far as regular pure copper cables, and you can’t use them for Power over Ethernet (they’ll overheat).
People buy them to save money since they can be a lot cheaper, but often end up having to re-run a lot of the cables in the future. Better to just buy the high quality cables from the beginning. “Buy once, cry once” as the saying goes.
yeah, this is a pretty common issue with CCA cabling, normally this is why people go for things like OFC wire instead, it also carries a little bit more current which is nice.
Sure, aluminum as the sole conductor is rare, but as you said, there is CCA, which is ridiculously common. CCA is mostly aluminum to save cost but is still 60ish% as conductive as copper.
Aluminium corrodes, and is a relatively soft metal.
Isn’t there a danger of someone shorting data to voltage by inserting this thing wrongly?
Also a good way to wear down your SD port if you remove this with any regularity.

Why?
Money whale hunting.
Woah boy, Elon is gonna be super jealous.
Steam deck modders rejoice
Doesn’t the steam deck use micro SD cards, I don’t think that these full-sized ones are going to be much help for those guys. Unless of course they come out with stainless steel micro SD cards but that doesn’t seem likely for obvious reasons.
Maybe you can just trim them!
Everyone thought 1tb+ microsd is impossible, but here we are
I guess if they made the chips small enough that the MicroSD body is just a shell, same thing happened with full sized SD cards (there was a time the whole space inside them was used, now it’s usually a small part of the front and the rest is just the body shape for compatibility).
ah yes, so you can get a card that will die before you manage to use all of it
