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.
Yeah pictures and videos is all I can think of. I am no photophile but I assume some small digital camera benefits from storage of the micro variety. Has me thinking of the 2015 movie Victoria, 140m straight, one shot, no cuts, and actually a good movie, pretty amazing stuff.
Given some reviews I’ve seen, it’s more than good enough for games. Loading times may be a bit longer, but not that bad. HDDs are in that range, and plenty of people use HDDs for gaming.
I can’t even imagine going back to an HDD for gaming.
I was recently given a laptop to check and make sure there was no info on it before disposal, and it took so long to boot into Windows and get into a usable state, I legit thought it was faulty.
And the worst thing was, that was a fresh install. Somebody had already cleared it.
Games are just so stupidly big now. They’re pushing 200GB. To fill 16GB RAM from SD (and not all games load that much) would take 3 minutes. The SSD can do that in about 6 seconds.
Yeah, there’s no way I’d be playing a 200GB game on something like a Steam Deck. Most games I’m interested in playing on a SD is something like 20-50GB, and most of that doesn’t need to be loaded to play.
My GoPro can record 4k@30fps. A 20-25min video is 5+gb. The newer GoPros will do 8k@60fps i believe, maybe only 30fps. That will take up a lot more space.
The cards have to be the higher speed cards to be able to record those resolutions, but if I were a person that recorded a lot of stuff, having a card that large would be nice for a day long session.
Sneakernet. There’s places that don’t have access to get l good Internet and relatively inexpensive storage like this allows them to buy and trade media and consume it on inexpensive devices like a cellphone.
Flash modding iPods is a cool use case for larger-capacity SD cards. However, the limiting factors seem to be the database file for the songs on the device and the RAM available.
At a certain point you get diminishing returns on the card capacity as you couldn’t fill up the card with songs and have them all be indexed without the iPod crashing. In these situations, one can be fine staying at 128 or 256 GB.
Why would someone wanting to store huge amounts of data to put it on a storage device that is the most fragile/short lived?
short term storage of uncompressed high resolution data
I don’t think microSD has the write speed for that, might be more useful for HD surveillance cameras

Even full 4K HDR Blu-ray rips come in at about 30GB an hour.
That’s 500MB per minute which just about fits in the 10MB/s of UHS Class 1.
I would consider those fairly standard these days. You’d have to have picked an extra shitty AliExpress special to not have your card meet that.

Games, the easiest way to expand the storage on a Steam Deck is a micro sd card.
SD card is limited to 100MB/s iirc.
It may be simplest, but it’s far from ideal.

I have an SD card with windows installed so I can run windows games without dual booting. It takes a while to startup, but is fine once it gets going.
Certainly not ideal, but that’s a whole OS and it’s decent.
Steam deck
Right, the 1Tb of internal storage and the 1Tb SD card is still really cramped if you play a lot of games

Good for straight off the camera
People doing production on their MacBooks might be a target per the small form factor.
They’re awesome for modding iPods, though my music library’s probably less than 1 gb.

Unmodded low-end steam deck.
Security camera run time.
DSLR for events.
