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.
Seriously, my plastic cookware is terrible
But there’s no better way to make a really traditional dioxin omelette.
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
How strong is aluminium compared to steel again? Oh right, its butter…
Cool
Why tho
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.
sounds pretty metal
Cause it’s metal.
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?
What good is a stainless SD card
Better thermal conductivity and in turn dissipation than plastic does tend to longer lasting flash chips, how much this change means in real world practice though remains to be seen
Heat is a flash storage killer of all kinds
It’s hard to believe that it would have taken 25 years for the many SD card builders out there to figure out that a heat spreader could solve the degradation problems.
Why would they want to solve an issue that causes you to need a new product from them
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.
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.
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).
Woah boy, Elon is gonna be super jealous.
ah yes, so you can get a card that will die before you manage to use all of it
