SD cards finally expected to hit 4TB in 2025
(arstechnica.com)
Now can we please get them back in phones?
They are in some phones.. Shop around :)
Yeah, just like headphone jacks. Oh wait...
They are, but mostly in budget phones. If you want a flagship camera or processor as well, you're sadly out of luck. And god forbid you want a folding phone.
Which is pretty stupid because you'd think that it would be really logical to have a way to have plenty of storage for those flagship cameras which would fill that lame ass basic storage... I mean do those flagships have more than a TB of storage? I'd think not most models.
I would bet money that phone makers such as Google keep storage low to steer people towards their cloud storage options.

I know, and I do, but the point is choices shouldn't be so limited. They should be standard.

Come on guys, I've had an 8TB microsd card since 2018...my files just start to act funny whenever it is fuller than 8GB ;)
Finally /s
Finally! Been waiting for this for since Pacman wouldn't fit on my punch card. 2025 here we come!
Thank god. I didn't want to live in a world without 4tb SD cards anymore.
Meanwhile I'm struggling to find 4MB SD cards, so I can easily overwrite it with random data to securely wipe it between uses.
How the heck do people with 4TB SD cards do data hygiene wipes of their medium before crossing international borders? That would take days..

They don't

I assume you're joking, but if not: the 4MB of flash you see is not mapped 1:1 with 4MB of actual flash on the SD card. Instead there might be something like 5MB, but your OS only sees 4MB of that.
The extra unallocated space is used as spare sectors (sectors degrade and must be swapped out) or even just randomly if it somehow increases IO performance (depending on the firmware).
Erasing the 4MB visible to your OS will not erase everything, there still may be whole files or fragments of your files sitting in the extra space. Drive-vendor specific commands can reliably access this space (if they exist and are available to you, which they mostly are not). Some secure erase commands may wipe the unallocated space but that's vendor specific, not documented and I don't think even supported over the SD interface (although I might be wrong on this last point).
Encryption and physical destruction are your best bets.

I don't know what your particular situation is but if you're just using it on computers you could use LUKS or BitLocker or FileVault. Then if you want to wipe it, you only need to destroy the key and the data is rendered effectively gone.
Yeah that's best for most things, but SD cards are generally used in situations where that's not an option. Namely for use in (video) cameras.
The other situation is when I need to transfer a large file to someone else's device where encryption isn't an option (rare but happens)
I can't fathom a good reason for 4TB SD cards.
Most cameras have CF Express which is probably 5-8 times faster.
Even UHS-III is 600MB/s while CF Express Type B is hitting 4GB/s.
Even so, why would you risk 4TB of data on removable storage.
CF Express is also running PCI-E. This article isn't talking about SD Express.
I think it's primarily targeting the handheld gaming market
Steam games. I want to have all my 50-100 GB games available without having to decide what to uninstall.
Currently I have two 512gb SD cards for my Steam Deck.
If it craps out, it's okay.
We need a better storage solution than SD cards…
Doesn’t the steam deck have an upgradeable nvme drive? That would be a much better solution.
~~80mm~~ 30mm m.2 drives are to much of a niche
I think you mean 30mm (that’s what the steam deck uses, 80mm is the standard).
At about $80 per TB, it is more expensive than the 80mm ones, yes. But still comparable to SD cards an much faster and more reliable.

My laptop has an SD card slot. So if this were reliable I could add a significant permanent storage capacity to my laptop.

If you set it up properly (like using apps to sync folders) a big enough sd is like local "cloud" service.
I was thinking about it recently, after my phone data were very close to being deleted (I managed to prevent it eventually), I was angry at how not having an sd slot caused me so many issues. If I had a 1tb sd I would just autosync app backups and files to my card and not worry ~at all about losing data from bootloops etc.

I would happily use one for my music and movies to access them on the go. I already have copies elsewhere, so it would be no big loss if the card died.
In addition, manufacturers will make a smaller and easier to lose format.

Do people setup RAIDs with sd cards? There should be a super mini box for a sd card RAID
I doubt they would be reliable enough for a RAID array. It would be much better to use m.2 drives.

More writes, more failures. SD cards work best when you write once and don't delete it for a long time

I’m guessing with a three day dump estimate? Thermal throttling on SD cards is brutal.

Yeah but when can I get a 4TB floppy?
If only I could get this much storage on my Mac.
Switch is old now.
That's nice, but I'm more interested in prices coming back down. The manufacturers have been pumping up storage prices even though demand has gone down by artificially constricting supply.
Tempting, but I'm waiting to see whether SD cards catch on before buying in.
Aren't SD cards slow and prone to failures?
The ones used for 4K recordings are not slow 100+MBps, I won't say prone to failure as such, flash storage can only handle a finite number of writes but we can mitigate that by using wear leveling.
That's pretty slow for terabyte sized storage. And slow compared to the alternatives, too (600 MB/s or Gabs/s).
Spinning hard disks are faster than this, too. Have been for decade(s).
I wish SD Cards also had some specifications for random access speed.
I used to have a UHS-I SanDisk card which felt much faster than my current UHS-III Samsung card. It's really evident when searching through the storage, waiting for photo thumbnails to cache, etc..
I am not sure whether to go for a UHS-I SanDisk or UHS-III Samsung next. That SanDisk might not handle higher bitrate 4K.
