2TB microSD card is on the way early next year
overkill.wtf

A 2TB MicroSD card really is a modern marvel in engineering.
One of my teachers broke the compilation record of compilation submissions per day, on the computing center, with punched cards.
On my first trip to a computing center of the post office during high school, they still used punched tape.
The modern SD cards are indeed a wonder.
Amazing how we went from 1TB 2.5 inch drives to 8TB m.2 drives and 2TB microSD cards in 11 years. And it would be more like $7k in 4TB drives than $130k. Put $130k of modern drives in the same shoebox and you're probably into the petabyte range. Go to the then-top of the line microSD milk jug and it's getting up there with these 2TB cards.
2TB / 149MB = 13,422 minutes == 223.7 hours == 9.32 days
I'm being facetious of course but I was surprised by just how much storage space I needed to record security cameras. I have a mix of 4k & HD, and 10tb doesn't even get me a month of 24/7.
Not sure what security cameras you’re using, but mine all use H.264 1080p compressed streams. I get about 15 days worth on a 2TB spinning rust across 6 cameras.
Even going by your own numbers, you almost certainly are using compression too. 9.32 days on 2TB does not get you a month on 10TB if you “have a mix of 4K & HD”.
So 2TB lasts 37 days, meaning blowski is right.
Of course powering that bodycam will be a different matter.
Take the Axon Body 2 as an example, the gold standard for police bodycams. According to its specs [0] it'll record 12 hours of 1080p video on its 64GB internal storage.
So using H.264 it produces 64gb/12hr == 5.333 (repeating of course) GB/hr, making 2TB / 5.333GB == 375 hours, or about 15.625 days

I’m not double checking the math but that’s insane, 1.4 million, insane.
As a technical person, my mind keeps getting blown.
I use two layers of thin black foam. The top layer of foam sheet has cut-outs for the various types of media except microSD card, which is held in place with a small dab of glue. They're pressed against the glass and has survived 2 moves without issue.
How about when you tell them it can store 38 seasons of TV shows in HD?*
Or 40 dual-layer Blu-Ray discs?
Does it seem like a lot or a little?
*Assuming 4 GB per 60-min drama episode in 1080p, and 13 episodes/season, all of which is pretty ballpark.
30C3 had a fun talk about the internals of mSD cards.

Anyhow, coupling the LPF to the power LED (and having a software controlled power LED in the first place) is a very Amiga thing to do. It's one of the platform's many nice idiosyncrasies.
Zero.
Not risking my data nor tribe in those things anymore even though I love that they’re small and cheap. Ideal for large media which doesn’t require too much bandwidth.
Even finding a microSD extension was tricky when I wanted to mess about with the hardware.
You cracked and bent a microSD card? How did that happen?
SD cards are many, many times larger than you think they are - often hundreds of times larger. This is because they use wear leveling to avoid read/writing too much to any one bit.
It is quite possible that this one SD card could have hundreds of TB of storage space on it. I have often wished there were some easy way to access all of this space for situations where you know that you only want to write once to the card - meaning you know you only want to write once. Would be great for storage.

Current US debt is almost 34 trillions? https://www.usdebtclock.org/
1 KByte = 8 * 1000 = 8 000 bits
1 MByte = 8000 * 1000 = 8 000 000 bits
1 GByte = 8000000 * 1000 = 8 000 000 000 bits
1 TByte = 8000000000 * 1000 = 8 000 000 000 000 bits
2 TBytes = 8000000000000 * 2 = 16 000 000 000 000 bits
All values approximate.
The coming standard claims "up to 2GB/s possible." [1], and at this "speed" (of adoption, that is), this is not coming anytime soon.
[1] https://www.pcworld.com/article/2124706/sd-express-9-1-new-s...
SD card users who care about speed have UHS-II equipment, but SD Express and UHS-II use mutually incompatible high speed signalling on the same pins (so cards and readers are only supporting one of the two - I guess technically this could be fixable with special purpose chips, but at large cost).
Users who care about speed but not about SD card compatibility are already using CFExpress, which is supported by most modern professional cameras and has much better hardware availability than SD Express.
"The upcoming 2TB card, dubbed the 'EXCERIA PLUS G2' is said to have read speeds of up to 100 MB a second and write speeds of up to 90 MB a second. This 2TB size now hits the upper storage capacity of the defined SDXC standard."
Not sure about IOPS but if you're streaming media or large game assets, sure that's fine.
They are indeed different projects. GrapheneOS is maximum security possible. DivestOS is best effort security of old/EOL devices to prevent them from being completely e-waste.
> so one is limited to generally the apps
It has the only unprivileged microG implementation, please read this: https://divestos.org/pages/faq#appCompatibility
Device manufacturers will sometimes list a lower limit than what the device could actually support, simply because there were no larger capacity drives/memory available for testing at the time of release.
I've seen this a few times with ThinkPads, not sure about phones.
But anyways, the limit exists, and this means that whether your device can support larger SD cards after it is released depends on whether the driver is getting updates or not. Android phones are quite known for not releasing driver updates, although often there is updates for Android phones as well. Thinkpads are IBM computers, and the update story is way better there.
but phones that advertise low capacity limits are probably also not wiring the SD interface for high bandwidth. it's not unusual to see internal flash capable of 100MB/s but SD interface only capable of 10MB/s :(

It's like with HDDs, very few consumers are buying these 20 TB HDDs. Unlike HDDs, MicroSD is largely a consumer product.
I have an SD card for the online-only titles, but it's pretty small IIRC.
But yeah, this still seems like a major use case for larger MicroSD cards.
Using 1TB as my backup size I keep my active development projects to a size limit of 1TB. That’s fine for code, it can fit all type typescript I want. I’ve began branching out into asset heavy projects, such as video editing and game development, and that 1TB limit is feeling more and more constraining. Now every quarter or so I “archive” projects out of my documents folder, which is a lengthier backup process.
I know there are cloud based backup solutions, but I find this way to be cheaper and having a physical copy to hold gives me a feeling of security.
4K60p video takes up a lot of space..
When I was looking at the Galaxy S23, they also had their Midrange model, and that had an SD card slot. But it wasn't the hot new flagship phone.
Given the technical limitations of these devices, already storing that much footage on a card that is so slow to backup and with such limited rewrite lifetime seems insane. I love the idea of 2TB in such a tiny package, but the reality of who would actually buy these in large numbers and for what does not quite seem to line up with the tech.
Although I guess a 1 TB card would still cost me a whopping 108€.
How long does it even take to fill the drive?
microSD are meant to easily store a local copy of your data, not to be a reliable long term storage.
You can also use it to store useful but not unique data like games on a switch or a Steam deck. If the card fail, all you lose is the time to redownload everything. Anyway except if you do a lot of video, the really important data (the really personal data you’ll want to backup) is rarely in TBs. It’s mostly pictures and documents.

And then anyone else remember the 16 MB Memory Card for Playstation? That was $20 in the early 2000s I believe
Crazy how much things change...
Sadly, when the vita came around, the only way to use an SD was to hack it and use an adapter in the game port. Since the vita card format was smaller than a micro SD.
(caution: read the one-star reviews)
For example, you could get a "1TB" card at a bargain price, less than 10% the cost of a legitimate 1TB card. But the actual capacity would be something like 8GB, and the firmware was hacked to report a larger capacity than actually existed.
Steve Gibson has a free program to test for these fraudulent cards:
But yeah, there's plenty of fake high-capacity SD and SSD at suspiciously low prices. What gets confusing is that you can also buy mid-performance real 32 or 64 GB SD cards for as cheap as 2 bucks. Perfectly good for occasional cam or tablet use, after testing.
I'd certainly recommend testing any flash device you get, especially cheap ones. It might take eight hours to write and verify, but it's well worth it. (if you can abide disputes/returns)
Those who know, know that Algol-68 was 20 kbytes and it was one full roll of punched paper tape. Weighing 100 grams.
So, 2 TB would require 10000 tons of papertape. (2e12/20e3/10/1e3)
And as we all know Finland's yearly paper production is 4 million tons. Hence it could produce only one 2TB SD-disk worth of reliable paper tape storage in a day.

As in bytes/mm³ or bytes/gramm.
Assumptions: micro sd cards weighing 250 mg, resulting in 0.25/28 moles of silicon.
The actual metal storing magnetic charge in a hard drive is tiny also, with some drive platters being mostly ceramic. Regardless, if you were to personify the force of entropy, it would be greatly angered by humanity and modern computing.
>said to have read speeds of up to 100 MB a second and write speeds of up to 90 MB a second
is useless to say, especially when write caches exist. I only care about minimum speeds, short of in depth analysis. The card is V30, which guarantees 30MB/s write.
* Then there is the 2006 update microSDHC, max capacity was 32GB.
* And since 2009 we use microSDXC, max capacity is 2TB.
* In 2019, the next update came out, microSDUC, max capacity is 128TB. As far as I know there are no actual products yet.
You need a reader of the same type of your card or higher. Otherwise, it might not work at all, or you can only read the first x gb of your larger card.
I am not knowledgeable, but I know how to use Wikipedia.
That's why I was asking.
I had the same with a _much_ older device, which accepted 2gb, even tho it said otherwise.
Unfortunately the protocols that run on top, and the filesystems that are typically stored on them, both have maximum size limits.
Generally, laptops/desktops will have no trouble. Your 2002 camera on the other hand probably won't work with it...
I mean, I remember floppies and 5.25 format hard drives in the kb and multiple mb size too, but the gigabyte hard drive era seemed like a significant milestone, so it made an impression. That gb external drive was probably just multiple (4-8) 5.25 drives in a case.
1TB didn't make the same impression because we were already getting to the "more than you need for most use cases" range and the external formats were about as compact as the internal ones with laptop form factor drives.
But TB scale in a micro SD format... Yeah, that is a similar impression to the GB HDD era.
As you can imagine, infosec people are stressed.
whose filling up terabytes at this size?
I’ve lost a few 256GB ones over the years. Only once with footage on it. But it was a whole day’s worth of my toddler’s first time in Disneyland. We were all very sad.
