SD cards finally expected to hit 4TB in 2025
Now can we please get them back in phones?
look into chinese phones, vast majority of them have it
Speak for yourself. My Motorola g73 has a micro SD card slot.
Oh I know, I'm still on Motorola because they have unlockable bootloaders and SD card slots. But in recent years they've started taking them out of some of their mid-range models.
Point is there should be more options. Removing the SD card slot is just a bullshit way to push cloud storage.
Mine's got one.
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.
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.
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.
3-2-1
maybe a rpi-style headless micro computer with 2 or 4 micro SD slots: tah-da: supertiny, supersilent NAS with 0 peripherals except power cable, yet has redundancy and is just as small and portable as an external drive.
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.
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
Right. Like, my use case for SD cards is for my cameras. I want to take pictures and bring them home across international borders. And a 4TB card would be amazing, though probably not fast enough. I simply don't put files that I don't want people to find onto my SD cards in the first place.
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)
Encryption.
May I interest you in this $5 wrench?
Smash them with fingers.
In addition, manufacturers will make a smaller and easier to lose format.
That's just Micro SD cards.
I’m guessing with a three day dump estimate? Thermal throttling on SD cards is brutal.
The article says 10MB/s minimum write speed, which would take 4.6 days to transfer 4TB, so... yeah. Even with the "max theoretical transfer rates" of 104MB/s (which is probably just read if anything) that's still almost 11 hours.
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
You probably don't want it

It makes sense to go with NVMe drives instead for a RAID NAS as it's the same memory technology (and what mostly determines the price in all of them is the amount of memory) so the price per GB isn't any higher (probably a bit lower as size is less of a constraint), the size is still quite small (it's surprising just how small NVMe SSD drives are compared with the older SSD 2.5 inch SATA ones) and NVMe is a much faster interface than SD so that things is going to be way faster.
It think I saw some in AliExpress the other day, but for what I use my NAS, plain old HDs with no RAID for redundancy or speed are just fine.
Yeah but when can I get a 4TB floppy?
If only I could get this much storage on my Mac.
MacBook Pros have an SD card slot.
Did they add it back? That's good. But SD cards aren't really replacements for primary disks. It's silly that you can't get your primary disk as big as an SD card.
Tempting, but I'm waiting to see whether SD cards catch on before buying in.
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.
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.
This is the best summary I could come up with:
Western Digital will launch the SD card, which follows the SD Association's Secure Digital Ultra Capacity (SDUC) standard, under its SanDisk brand and market it toward "complex media and entertainment workflows," such as high-resolution video with high framerates, using cameras and laptops, the announcement said.
The spacious card will use the Ultra High Speed-1 (UHS-1) bus interface, supporting max theoretical transfer rates of up to 104 MB per second.
"Attendees will get a preview of the 4TB SD card’s full capacity and learn more about how it will expand the creative possibilities for cameras and laptops," Western Digital said.
Western Digital didn't say what the SD card would cost, but with its advanced capabilities and targeted audience of professional creators, the offering will likely have premium pricing.
However, Western Digital's announcement also comes as SanDisk's reputation for reliable storage is in serious question by professional and long-time customers.
These alleged failures, combined with frustration around Western Digital's limited response to reported data losses, could have professionals with work-critical storage needs consider waiting for another brand to make the leap to 4TB.

and i still cant use it in most phones cause there is no freaking port!
To be honest, SD cards are usually not meant for extending storage anyway. They should only ever be used for temporary storage like taking pictures and later transferring them to some other storage medium.
Who need that much storage on their phone? Honestly asking.
This isn't about phones. It's mainly about cameras recording 4k/8k video, and devices such as the steamdeck storing lots of games.
Cameras recording high bitrate video generally use a better format than SD
Me. I am basically trying to squeeze the desktop (PC) out of my phone, so there's a lot of "unnecessary" stuff.
For example, I am currently deciding whether to keep the 110GB of DVD ISO files which I can stream from my phone using VLC (on client side) which are served by nginx server from my phone (this way I still get all menus, just like with a physical DVD) or delete it and replace it with equally sized 110GB EN Wikipedia maxi .zim package, install kiwix-tools on Termux and set up nginx on Termux to serve as revese proxy to kiwix-serve so I could also host a mirror of the whole English Wikipedia, including (downscaled) images on my phone. I guess that sounds cooler than DVDs.
Or I should get a 512GB SD card and keep both.
I can't afford 1TB one.But yeah, that's just one example. My 256GB SD card is about to pop while my video and music collection (The latter of which which is also served using Navidrome server in Termux 🙂. For videos I just use nginx with material fancyindex theme.) keeps growing.
I already have to keep some stuff on phone's internal storage.Termux is godsent. Otherwise I'd absolutely have to get a PinePhone as I couldn't live with something as locked down as Android or even iOS without a nice terminal emulator.
Alternatively, I could benefit from pocket-sized passively cooled laptop.Phones don't have (full size) SD card slots, this is for cameras and such.
