    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.

    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.

      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.

    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.
