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 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.
and i still cant use it in most phones cause there is no freaking port!
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.
My laptop has an SD card slot. So if this were reliable I could add a significant permanent storage capacity to my laptop.
Valid point, but I think most built in SD card slots are on a laptop can read 100MB/s. Hopefully yours is perhaps USB 3.0 speeds.
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.
Hehe, I think I haven't caught up with the improvements, flash with 1GB/s transfer speed is ludicrously fast!
All SSD and NVMe are also "just flash", and reach 5GB/s and more, often limited by the available interface bandwidth until very recently.
Other formats can exceed that by caching & writing to multiple chips at once i guess.
Who need that much storage on their phone? Honestly asking.
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.
Thanks. That sounds pretty cool.
I won't mind that much storage, the 256GB I have are nearly full.
I'm using a 128GB phone and it's never full. But I export photos And videos off it once every 6 months. If I didn't I'd need 1TB phone.
Same. I should have gotten a 512GB Micro SD. "I could never use that much storage." Yeah, I could.
What do you use all that storage for?
Apps, photos, audio books, and the OS.
and the OS
PinePhone?
Nope just plain old Android, haven't gotten around to using something better
Storage needs kind of grow to the size of their container. Like a goldfish.
Really depends on the person. I have never managed to fill up a 128 gigabyte phone, but that is because I am blind, so I am not taking pictures in 4K videos. The biggest thing on my phone is my music collection, which only takes about 5 gigs or so. This phone that I have now is a 64 gigabyte phone and while it's mostly full, it's still not there yet. According to the Android settings, I still have about 23 gigabytes left on this 64 gig phone. It says I have used about 64% and if this were a 128 gig phone, that would be about 32% or so.
Phones don't have (full size) SD card slots, this is for cameras and such.
This isn't about phones. It's mainly about cameras recording 4k/8k video, and devices such as the steamdeck storing lots of games.
Unfortunately, the card mentioned in the article is far too slow to record high resolution, high bit-rate video from even older "pro" cameras.
Yeah, I've filled 256GB pretty easily by recording on an action camera all day, maybe for a couple of days. 4TB would be very convenient for a holiday.
That make sense. Thanks.
