When I started my career I used to have to manage tape backups for the company I worked for using LTO tapes that stored a huge 100 GB lol
I am slightly confused why they use UHS-I instead of UHS-II (or even UHS-III) for such a big capacity. Seems like people needing so much capacity probably write a lot of data in a short time. UHS-II is 3 times quicker.
Then again maybe they are aiming for devices that can’t even run UHS-II
Could be a trade-off issue. They can get capacity or speed but not both yet.
Or it’s cost-prohibitive ATM. As in, they could get both, but you’d pay a ton for it.
I can imagine this being useful for cases where you write a lot of data over a longer time period. Think CCTV (with low-medium resolution). You can keep a sizeable archive locally and never have to swap cards
I assume larger capacity means longer endurance, too, since you’re not constantly rewriting the same cells.
It’s SanDisk, I expect the opposite - that every cell increases the volatility and chance of catastrophic failure.
Oh yeah cctv could be a good option indeed.
ah finally, i can buy a micro sd card for 500 dollars, the same price as a gazillion terabyte harddrive, and get less reliability out of it.
yeah, but you can carry it with you at all times if your phone takes an SD card.
although, can they use one that large, or is there some restriction?
I think most phones have a 1tb cap … But nowadays most phones don’t have SD card slots so I don’t know where that has gone
I’d say it depends on the phone.
Why would someone wanting to store huge amounts of data put it on a storage device that is the most fragile/short lived?
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.
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.
I bought a 1TB SD card for my go pro/drone the other day. In theory it’s good for 16 hours of recording non stop.
I also have both a 512gb and a 256gb sd card for my dash cam, I’d really like to get a compatible 1TB card, but 4TB would be even nicer. Maybe I’d be able to go a month without offloading the card.
Video Cameras
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.
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.
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.
Good for straight off the camera
Steam deck
Right, the 1Tb of internal storage and the 1Tb SD card is still really cramped if you play a lot of games
Why would anyone need a 24TB HDD?
Because in the time we have gone from 4GB SD cards to 4TB cards, movies have gone from being 700MB to 70Gb, and games from coming on a few cds or dvds to requiring a mountain of them - Baldurs Gate 1 came on 5 CDs, BG3 would require around 200 of them.That 4TB card has only space for 26 games, if they are as large as BG3.
The original Baldur’s Gate came on a single CD and had full install size of under 600MB. It was also possible to do a partial install and to load files off the CD at runtime.
An uncompressed CD audio soundtrack, maybe?
(That doesn’t appear to be the case for Baldur’s Gate in particular since the discs pictured in the listing have “compact disc data storage” logos, but I do remember some '90s games being like that.)
You could do that with a lot of PS1 games. The first track was data, the rest were just regular CD audio tracks.
This got rarer later on, once they realised the could fill the discs with FMV sequences instead.
This got rarer later on, once they realised the could fill the discs with FMV sequences instead.
Speaking of PS1 games and disk-filling FMVs: Final Fantasy 7 on the PSX comes on 3 disks but the actual game itself is duplicated on all of them and you can swap them out during gameplay, and the only thing that happens is that it plays the wrong FMVs.
It all breaks down to the actual “game” taking 133MB, plus few hundred for the uncompressed pre-rendered backgrounds, out of the available ~1.8GB (according to this old post about how a Nintendo DS port could easily fit on a 256MB flash cart.)
In this case, the question was rhetorical - the original release of BG1 takes 5 CDs, and the sixth is the Tales of the Sword Coast expansion. Installed the game takes around 2.8GB IIRC. They did eventually re-release it as only a 3 CD set because they could cram more data on a single CD by then.
Last I remember, Baldurs Gate was on 6 separate discs, but I haven’t installed it from those in probably 20 years.
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
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.
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.
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.
They’re awesome for modding iPods, though my music library’s probably less than 1 gb.
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.
Unmodded low-end steam deck.
Security camera run time.
DSLR for events.
People doing production on their MacBooks might be a target per the small form factor.
Wasn’t sandisk particularly unreliable or am I mistaken with the brand? I remember slme problem with SDs failing prematurely
The mockup image is kinda misleading (article admits its crappy lol).
afaik there aren’t any current microSD cards 1TB+ that have a u3 or even u1 speed because the increase in storage size comes at the cost of speed.
The development is definitely cool, but the physical size of a microSD is probably very challenging to design around without sacrificing something.
I feel like this is a product looking for a market. Why would anyone ever trust that much data to something so fragile and easy to lose?
They’re not for long term storage, they’re for transient storage like photography, in particular stuff like surveillance cameras
if you want long term CCTV setup properly you should be using ethernet connected security cameras and then transmitting it back to a central server with a hdd always recording. It’s much more reliable and way more cost effective, just requires you running an ethernet cable to where the camera is.
Yeah but the live feed and remote downloading sucks
with ethernet the live feed is perfectly fine, and there is no remote downloading, it’s all streamed over the ethernet to a central box which handles everything from there. You might need some decode/encode capabilities, but to my understanding a lot of cameras will run multiple hardware encodes straight from the sensor over to the network already. So you probably don’t need much.
What brand do you have?
It depends on the type of location, small remote locations might not even get their own local network
I use a 2tb (iirc) in my steam deck. Perfect application for that… Low rewrites, but totally expendable/replaceable data.
Filming 8K in a raw format maybe?
Also useful for devices where you want more storage but the device only has an SD card slot, or other slots are already occupied or sd card is just easier such as phones, Nintendo switch, steam deck, ultra light laptops, raspberry pi…
Also could be handy for smuggling banned movies/tv shows into authoritarian countries that block or outlaw unauthorised VPNs?
Though for the price these will retail for, would probably be easier to take more, smaller capacity cards…
It’s only 104 MB/s. Not enough for RAW video.
4k Drones, upgradeable phones, DLSR cameras, Data per weight etc.
I own a 1tb ssd for my Steam Deck, literally 0 complaints, runs real fast, can’t feel any heat, never need to take it out other than if I’m factory resetting, it’s perfect! (though Valves next deck should just have a bigger ssd slot)
I’d love them for my dash cam if they were affordable. My camera records in front and behind of my van in 4k, so that’s 90-100 gigs an hour. I leave it running as a surveillance camera when I’m parked, so just going to work and back in one day would use over a terabyte.
Why would you continuously record? Just record motion events and you won’t need a card that large at all, plus it will last a lot longer.
Busy parking lots always have motion.
Just need to set them up in a raid configuration for redundancy.
Redunda-what?
The only RAID is Zero.
Gotta go fast
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
This is obviously not for large scale storage. But for stuff like cameras, which uses ever larger files for raw images
I totally get that… Here’s the thing though, at least in Norway a 1tb micro sd card costs 2200kr (~$203). If we extrapolate the price for a 4tb one, that’ll be 8800kr(~$813). If you or a company has the kind of money to spend almost a grand on a storage device, doesn’t that mean that the footage/photos are pretty valuable? If you had the kind of money/were going to record super valuable footage, wouldn’t you work hard to use cameras/recording systems that were capable of recording to redundant drives?
What I don’t get is what market section this product would even fit in. It’s too expensive for regular consumers, and also has terrible value. It’s not good enough for professional settings because it has no drive monitoring, nor does it have redundancy. It isn’t fast enough for the kind of footage that would require that kind of space(unless you’re recording a month long realtime video).
Also imagine how horrible the transfer speeds would be for individual photos when the os has to initiate a file transfer. If we say each photo is 20mb, that’s almost 200k photos. Yikes…
yeah no absolutely just use a proper CCTV setup at that point, it’s cheaper and way more reliable and maintainable.
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.
I’ve had a usage tier for storage that looks like this
Temporary storage
- SD cards - unreliable storage you use temporarily to store pictures and videos before inevitably moving them to a more reliable and permanent solution.
- USB drives (hdd ssd etc) - used for when you you want to move files faster or more conveniently than over a Lan.
Permanent storage
- Nas, internal drives, tape drives, etc - for when you want to store a lot of data with configurations that allow you to use redundancy.
The issue with super high capacity SD cards for me is that they’re still fragile and prone to failure. When you allow someone to store that much data, it’ll be used as a more permanent medium, and since it has a lot of storage capacity you end up with a bigger data loss when it dies. Imo having 30 128gb SD cards would be better because if one dies or breaks, you lose 128gb and not 4tb.
Tldr I think 4tb micro sd cards are stupid.
No one is using SD cards for data storage, I hope.
I mean, it’s where I keep all of my important tax documents in pdf and my old family videos. It’s plugged in this here chromebook. Haven’t needed to take it out since I got the thing during a sale for $160. The chromebook that is. I don’t remember what 16Gb cost back then.
Please for the love of got put that somewhere else.
This reads like a joke, but trails off like it’s sincere…I don’t know if I should be concerned…
And after you spend 14 hours filling it with data, it falls out of your shirt pocket when you lean over to tie your shoe, gets caught by a gust of wind, and is gone forever.
The raspberry pi is about the worst case scenario for SD cards. It may be idle, but an operating system is still making constant reads and writes, which absolutely eat through an SD card
I’ve had better luck with pro extreme cards made for dash cams, etc.
There is a thing called Log2Ram that can help with it for Pis. I run it in my PiHoles
I’ve started just booting them from USB. I have Home Assistant running on a pi with an ssd in an external enclosure and it’s been completely issue free.
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.
this is kind of why we have RAID, but arguably, you should literally just not be using RAID as a backup. Failing drives should be prepped for in advance, rather than dealt with in real time at the 20+TB scale.
The primary advantage to such dense HDDs is price, and power efficiency.
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.
also im not sure i agree with the phrasing here, the drive does become “more important” but that’s because it stores more data, there is literally more for you to lose in the event it gets destroyed. You should trust nothing ever, yourself included.
Worst part is that SD cards don’t have SMART, meaning you don’t know when they’ll die.
I mean, SMART doesn’t help much with knowing about HDDs’ death either. It’s more often they don’t show up at all, so you can’t even check SMART.
It’s not about the death. It’s about if it’s going to die. I’ve seen smart errors weeks before a hdd died which gave me time to back that data up.
I see what you mean. It helps predict that, but not always. This is still a lottery, and the absence of SMART only makes it a little bit more of a lottery.
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.
I mean, it exists, but it’s experimental and extremely expensive
What SD cards are you buying, and where are you using them?
I’ve been using a 256gb Sandisk high endurance SD card in my dashcam since 2021 (when I lost the first 2 I’d bought in 2018) and it’s still perfectly content writing a 4k + 1080p video for about 16 hours straight every single day. It wasn’t until last year I got a 512gb Samsung Pro Plus drive to split the load/act as a backup.
Didn’t we only just start getting 2TB microSD?
At this size you could carry your backup with you all the time or store it in your car encrypted.
They’re slow as all hell, which is more pronounced the larger these are in capacity.
You’re best of getting a tiny m.2 enclosure for something like that.
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.
1TB may have seemed unlimited back then, but now with 8TB, if an uncompressed Blu-Ray is around 50GB, that can fit 160 Blu-Ray movies. Now, 160 movies may seem like a lot, and it is, but think of how many movies there have been overall over time.
You can never have enough storage.
You’re only getting 4 TB the size of your pinky nail. 8TB is the size of your thumbnail. Most people can’t be arsed to read the article, but you couldn’t even read the headline?
More like big toe nail for the 8 TB.
Yall have big digits
Our first family PC had a 1,3 gigabyte drive. That had Win ‘95 on it, productivity apps, bunch of games, etc. This was a time when you could actually still run games off CD-ROM’s without needing installs.
These days, my phone has over 200 times the memory. It’s still amazing to me.
Same thing with SD cards. When I started with digital photography, a 32 MB card was big. My current camera takes images that are too large to fit on it! Early cameras even had floppy disk storage, if you can imagine…
I think our first family PC had 40MB of storage, and we loaded optical discs into a caddy before inserting them. That was in the late 80s.
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.
Tecra was the high end model line and “CDT” in that model name means it had an active matrix LCD. You were already living the life of mobile luxury over most folks. Adding that 1GB HDD was rubbing it in our faces at that point. :)
Huh. I can see drones, action cameras and spy cameras being able to store lots of super high quality footage with this. Like, so much footage it lasts longer than the battery.
It’s niche, but I can’t see the use case.
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.
The micro SD is 4 TB. Only the full sized SD is 8.
Yeah but in 2-3 years I’m sure they will have an 8 tb micro SD out
