    Why would someone wanting to store huge amounts of data to put it on a storage device that is the most fragile/short lived?

        I don’t think microSD has the write speed for that, might be more useful for HD surveillance cameras

          Uncompressed 4k stream @ 30fps and 24bpp would be 5.7 GB/s. The top regular SD card speed, UHS-III, maxes at 0.6 GB/s. SD Express, where a PCIe lane is added, goes to 3.9 GB/s.

          So, yeah, going to need at least some compression. Good news is that just a little compression can go a long way.

        Right, the 1Tb of internal storage and the 1Tb SD card is still really cramped if you play a lot of games

    All I want is higher resiliency SD cards. It must be a technology limitation with being unable to fit a good controller in there or something because I would gladly sacrifice speed and capacity for something reliable in a lot of my applications.

    What would anybody even use 4 TB SD card for? Storing a shit-ton of pirated movies that you can watch on your phone? Aside from that I have no idea. 256 gigs is probably more than enough for anything a normal user would do on a phone.

    Wasn’t sandisk particularly unreliable or am I mistaken with the brand? I remember some problem with SDs failing prematurely

    and both are described as SDUC UHS-I cards that are “built for tomorrow’s smartphones, gaming devices, drones, cameras, and laptops.”

    Gaming devices: ✅️
    Drones: ✅️
    Cameras: ✅️
    Smartphones: ❌️

    Basically every current flagship phone, and you know that’s what they mean, has done away with expandable memory…

      Which is utter bullshit. Especially since a lot of lower end phones have the option for dual sim or one sim and sd. There is literally no reason for flagships to not have that and make file transfering easier.

    This is the kind of discussion i’m here for. Thanks everyone! I didn’t know SD and micro SD cards where this unreliable but i always use them for short term stuff or content that is backed up somewhere else so i think i’m good.

    I paid $100 for a massive 1TB hard drive when they first came out years ago. Thought a TB was essentially unlimited and wasn’t sure if it could ever be used.

    What a crazy advancement to get to 8TB the size of your pinky nail.

      I paid like $150 for a 1GB hard drive on my Toshiba Tecra 510CDT back in the 90s. The guys at the computer store weren’t sure if it would even work.

    Sigh…

    A couple of years ago there were discussions on how stupid 20+tb harddrives were, mainly because they are so slow that the time it takes for files to transfer to a spinning disk was too long.

    Let’s say you have a good 20tb drive and it can transfer files at 200MB/s. To fill that drive, it’ll take 1 day and 8 hours of continuous transfer. If it’s failing, and you’re trying to get as much off of it you’re screwed.

    Now let’s think about that micro SD card. It’s 4tb, and let’s be gracious and give it a v90 speed class. That’s 90MB/s. Looking at a calculation for the time it takes to fill it up, we’re sitting at about 14h and 14 minutes. Worst part is that SD cards don’t have SMART, meaning you don’t know when they’ll die.

    From my experience, even good SD cards die in my raspberry pi running pihole, and the cards runs idle almost all the time.

    Also there’s this thing that the higher capacity a storage device gets, the more valueable the data stored on it becomes, not directly because it’s high capacity, but because it’s more trusted by the user.

    Guys, gals and anyone in between, please get a proper storage solution, something that won’t fail spontaneously. If you need that kind of capacity, go for a Nas with spare drives, or at least get an ssd.

    /end rant

      Not all use-cases require a high speed:capacity ratio.

      I mean, I have an 18TB USB hard drive, which sustains transfer at about 50MB/sec in practice. It is nearly full, and its level of performance has never been a show-stopping problem.

      It’s hard to imagine a use case where a NAS would be a viable alternative to an SD card.

    Def means my next phone I’m buying I make sure has a micro SD slot…

    I love emulation on my phone as a hobby and his is hitting the sweet spot where by the time I need to upgrade again in a few years everything up through PS2 generation should be full speed even on mid tier phones that typically still offer micro SD

    And 8 tb of micro SD is enough space to carry literally entire romsets for every system I like besides PS2/GameCube which is fine.

    SDUC supports up to one hundred and twenty eight Terabytes O.o

    Who in the world requires so much Storage on a tiny SD card?!
