@bot It has a little portal to another dimension built in. They could store infinite data in a single SD card, but it's way more profitable to limit it and just expand the limit every once in a while.

@bot this youtube channel has some graphical explanations. SD cards use nand flash memory like SSDs https://www.youtube.com/watch?v=YtBysgPOKx4

@bot OK there are tiny little electrical parts which can be induced to either block the flow of a low-voltage electrical current (on the order of about 3 volts) by applying a 30v or so charge to them for a few microseconds (thereabouts). They actually trap electrons onto a medium THROUGH an insulating layer using a quantum tunneling effect when this is done-- how this specifically works doesn't matter but the net effect is that on this part, the excess electrons make it resistant to the flow of the lower voltage charge. The parts that do this are called "floating gates." Anyway, take a few billion of those in sequence, some set to true or false depending on their charge state, and there you have your memory.The floating gates can later be erased to zero by applying a much higher voltage.Anyway these floating gates can be made extremely tiny on wafers of sililcon-- they don't use any tools to directly etch the circuits onto the wafers, but instead use a photolithographic process to project a much larger version of the design onto the tiny piece of silicon like a film projector but inverted. The light causes the parts we need to be non-conductive to become so. (or it might be the inverse, I don't remember the details too good)Anyway... yeah, there's probably a ton of details I left out and maybe a few I got wrong but that's a high-level conceptual overview.

@bot tiny memory cells made of multiple layers in a 3d structure store a charge in what they call a "charge trap" but idk much about it. this one is good too. https://www.youtube.com/watch?v=r-SivgEpA1Qi usually watch these videos on 1.5x speed otherwise they get boring

@bot If you know anything about transistors, floating gates are basically transistors but with the line that determines whether the current is blocked or permitted being held high or low by those isolated electrons I talked about earlier rather than by an active current from another circuit.

@bot SSDs are a lot faster, either because they have more flash memory chips/cells working in parallell or because they're just higher quality, more power-hungry memory.

@bot And SSDs are not quantum computers at all. The quantum effects are only used to pump electrons into the charge traps. There's no superposition of any individual bit, only an assurance that at a certain voltage, a certain amount of electricity will tunnel through the insulator into the charge trap which will represent a single bit with a definite state.

@bot @meowski The charge trap is a part of the floating gate. Whether the trap has trapped electrons or not determines whether the gate allows electrical currents through.

@bot a transistor gate in general is the connection that controls the flow of current through the transistor or how open the channel isi can't give you a detailed explanation of nand flash though. just watch those vids on 1.5x speed they're good

@bot @meowski Oh... you're asking why... OK, you're asking why SD cards being so much smaller can hold as much as large SSDs ok I get itThe reason is because the chips in SSDs are built to be able to be accessed VERY quickly. They may have thicker traces which can accept more current and therefore have less latency when being accessed. You don't have to wait the extra few microseconds for each data read to reach a readable voltage-- the charge propagates through them more quickly. SD cards are optimized for physical size.

@bot @meowski There are probably other reasons too but that's just off the top of my head-- it's because they're engineered to optimize for different things

@bot @RustyCrab @meowski Well that's a very simplistic way of putting it but yes. And density. SSDs are less dense, but they're faster. Cache adds a whole other wrinkle to this whole explanation, but I can summarize it just by saying they've added extra stuff to make writing and accessing data on the SSD faster.

@Bead @RustyCrab @meowski @bot depends on what you mean by that term... at the very MOST fundamental, they're very similar-- floating gates all the way down

@bot @RustyCrab @meowski @Bead in theory they should be about the same but from experience I'd say SSDs are more reliable, but that could be only because SD cards aren't tested as thouroughly to be a daily workhorse type of memory. They're for occasional reads/writes

@JAJAX @bot @Bead @meowski most ssds today include wear leveling. I would be very surprised if SD cards had that. If they don't then they're pretty much assured to fail sooner

@RustyCrab@clubcyberia.co @JAJAX@clubcyberia.co @bot@seal.cafe @Bead@nicecrew.digital @meowski@fluf.club I'm actually not sure if SD degradation is a thing, I pretty much only use them in my phone and in cameras, but you immediately dump the SD onto a laptop after shooting so it's never a concern. I should probably just find my old DSi and see if the games still run.

@bot 'electric traps', that's it. If the trap contains electricity, this means 1 (yes); otherwise this means 0 (no)
