Olympia NC560 Cash counter: can update to new bills from sd-card, the manual states "Micro-SD memory card with a capacity of 1GB up to 8GB".

We tried a 32GB card first, the update seamed to run fine. To finalize the update file is deleted from the sd-card. This all happened, then the device was stuck in firmware-update mode (undocumented state). Tried it again with a 4GB sd-card, update worked fine.

We assume the update file was spread beyond the 8GB boundary

That's a dangerous game to play when you were counting money! I seriously admire your hacker courage.

I'm scared to try an unauthorized card in my Nintendo Switch because I could lose my Zelda save file.

Game saves are stored in the console's internal memory. You couldn't put your save on an SD card if you wanted to.

The article mistakenly says "microSDXC slots" when it means "microSD" slot. Because SD, SDHC and SDXC all have the same physical form factor and slot you put them into, but vastly different electrical interfaces and protocols.

And yes, older versions like SD literally did not have the bits to even communicate cards with 512 GiB.

SD, SDHC, and SDXC are all electrically the same (though newer cards can also optionally support higher-speed interface variants with different signalling voltages), it's just that the original SD protocol didn't have enough bits in the protocol to support higher capacities. SDHC and SDXC are basically the same except that one uses FAT32 and the other uses exFAT as its standard format. You can often use cards above the official 32GB limit in SDHC devices if you can format them as FAT32. A lot of older SD card slots can also be made to support SDHC with a suitable firmware or driver upgrade because the protocols are really similar, but with some fields just being interpreted slightly differently.

No, I think it's correct. From Wikipedia [0]:

SDSC: 1 MiB to 2 GiB

SDHC: 2 GiB to 32 GiB

SDXC: 32 GiB to 2 TiB

SDUC: 2 TiB to 128 TiB

Yes, all four of those as "micro" go into the same "slot".

My point is that a "400 GB" card and a 512 GB card both are SDXC cards...

But the reference is to a slot and not a card.

So it's a microSDXC slot that doesn't support all microSDXC cards. Q.E.D.

Sure. The ecoboost Ford mustang. If you put the engine from a Mustang GT in the Ecoboost mustang, the crankshaft will explode. You can totally mount the engine from the GT in the ecoboost, it's the same frame, but the rest of the car is not engineered to support that much horsepower.

Not so much the crankshaft (which is inside the engine), but more the transmission and remaining driveline (driveshaft, differential, etc) become the new "weak points".

This assumes that the Ecoboost version isn't just a engine swap - it could be that Ford uses everything the same from transmission back, and just pops different engines and badges on. I don't know if this is true or not, though.

For instance, on their old Ranger pickup trucks (basically rebadged Mazdas), the rear axle on virtually all of them was way over-engineered vs the rest of the pickup:

While there were some differences between models, most of them used one of two sizes, and they just dropped a different engine and transmission in. In this case, depending on what you had, you might end up breaking other parts before the axle gives (the Ranger axles are a popular swap upgrade from the Dana 30 axle on Jeeps, due to it's robustness)..

I think the parent meant specifically with SD cards. I've personally never had issues using higher capacity cards in devices that didn't officially support them...

Back a few years I bought a large CF-card for a Canon 5D camera, which was just not recognized.

Ohhh my mistake, I thought they were looking for examples of this in other fields.

Presumably the crankshaft is in the engine, so it should be fine. The transmission, driveshaft, differential, and axles may not be up to the task, however. But it will be torque that breaks them, not horsepower.
