1TB microSD cards
- tehsauce 8y agoAs of about a year and a half ago. (Edit: nevermind, I must have been mistaken)
- izzydata 8y agoIs there anyone here that has a use-case for owning one of these at their current market price?
- zwieback 8y agoIf I was going to build a datalogger for work that could log more data for longer (while being away from any network) the $450 would be no problem. Some years ago I was working on a seismic sensor that could have benefited from more flash. For home use it would be a definite no.
- treis 8y agoHigh resolution video cameras would be the first adopters I'd think. 4k out of the camera can be hundreds of GBs an hour and 8k chews up even more.
- iwasakabukiman 8y agoThis was my first thought. I work in video production and we always carry around extra SD cards because our camera chews through them so fast. We use Sony FS5s and they can fill a 128 GB card in an hour with 4K video.
- mseidl 8y agoWith my 5d3 raw video I get 24 minutes of 1080p on 128gb. But I have to use a really fast cf card, because the sd cards aren't fast enough. It writes at around 100MB/sec for 14bit raw.
- Beltiras 8y agohttps://filecatalyst.com/how-to-move-large-video-files/ https://filecatalyst.com/how-to-move-large-video-files/ 553GB for an hour of 8k 88GB for an hour of 4k
- kalleboo 8y agoVideo cameras can be able to shoot at higher bitrates than a post-processed 25fps Blu-ray, just using the same calculator as that site for 60fps you get 164 GB/hr for 4k
- jws 8y agoWhich is about 45MB/second, about half of the published write speed for these 1TB cards. The SD standards have been moving up the transfer rates. The UHS-III does 624MB/sec. The new SD Express standard will do 985 MB/sec by presenting a PCIe Gen3 or NVMe directly. (Obviously more contacts, but they are backward compatible with the older interfaces.) They just announced the SD Express interface for microSD cards as well. I'm not sure any products are available for SD Express yet.
- jdietrich 8y agoThey're of limited utility in this application because of poor write speeds. Most high-end 4K cameras use Cfast, XQD, SxS or SATA recording media, because SD cards are a significant bottleneck.
- agumonkey 8y agogod.. I don't even use 720p more than once a month
- demarq 8y agoMy thinking is the following people: -> Status symbols, Mobile Phones are the new Cars and mobile stats are the new horsepower, so being able to brag you have a n extra tb of storage over your other colleagues might be a thing. Esp in mobile nations like UK and India -> Social media is slowly switching to video over still images (greater access to high bandwidth). So people will be taking editing and sharing more video instead of pictures and that increase storage requirements many many times over. I know most people who heavily use social media already find 32gb limiting when what they post most of are images. -> Gamers, most AAA mobile games require large extra content downloads that are in multiples of gigabytes. -> Geeks, because 1TB SD cards are quite a technological marvel. -> Mobile Cinematographers, Laugh now but this will slowly become a thing. Looking at Sony and LG offering more and more bold mobile cinematography devices like the Xperia X1. These phones are able to deliver RAW footage files. Also Nokia's latest five camera flag ship puts out RAW stills that can be 10s of megabytes per image. I see a proliferation on the horizon. -> Streamers, Mobile networks can be patchy, public wifi sketchy, and corporate internet to restricted so youtube, netflix, and showmax allow people to download movies to watch later. However low amounts of storage capacity currently limit the resolution of of content you can download. I believe at least two of these use cases will hold true in the near future. But at the current high prices maybe only Geeks will buy them.
- CondensedBrain 8y agoSomeone on a long trip with no reliable high speed internet could shoot in raw and never worry about space.
- munificent 8y agoWith my camera (Canon 5D Mark III), that's about 26,000 still images. On a busy day, I might take 200 photos. There is no way I would take a hundred day long trip and put all of the photos on a single card and risk losing the whole thing. Even if I could, I would absolutely use multiple smaller cards just to reduce the single point of failure.
- maxxxxx 8y ago"On a busy day, I might take 200 photos. " I can easily see a pro taking 20000 pictures during a sports weekend or an airshow. I took more than 3000 during an IndyCar day with several races.
- ddoolin 8y agoYep. I work for a top motorsports company and our photographers take hundreds of photos in a very short time (we have multiple drivers), leading to many thousands over an entire race weekend. The images are uploaded immediately and used for classification and analysis via ML.
- maxxxxx 8y agoAt the IndyCar race I was shooting from a parking garage roof and there was a guy who took pictures and videos of all cars and streamed them to the team for engineering analysis. this was new to me but makes sense. What series do you work for if I may ask?
- ddoolin 8y agoSorry, I have a habit of making comments and not following up in checking replies. I work for each NASCAR series, so Cup, Xfinity, and Truck. We also work with ARCA, NHRA, and IMSA but I'm not sure if this particularly level of photography or application will ever make it down to the lower series.
- trumped 8y agoin your phone, to be able to keep a local copy/backup of your family videos, your music, etc...
- adrianmonk 8y agoMaybe something like a dashcam or security camera. Something where more hours of video footage retention is better.
- nicoburns 8y agoNo, but the great thing is that prices seem to cascade down for very size when a new size becomes available. These ones put 256gb cards firmly in the affordable category for me.
- LAMike 8y agoWish I could fill up the world's knowledge in 1TB and put it in a low cost tablet and deploy it to a billion underprivileged people in their language to spark the next Einstein, along with millions of other educated people who were able to improve their lives through data
- rexpop 8y agoIs that really what you think the next Einstein needs? No, she needs Colonialism to get off her neck. These millions are under-educated only because we have smashed their societies to burgle their commons.
- sctb 8y ago> Eschew flamebait. Don't introduce flamewar topics unless you have something genuinely new to say. Avoid unrelated controversies and generic tangents. https://news.ycombinator.com/newsguidelines.html https://news.ycombinator.com/newsguidelines.html
- rexpop 8y agoThe word "unrelated" is awfully subjective. I could, of course, improve at spelling things out, but one never knows how much elementary illustration is necessary. Of course, no one believes their own words to be flamebait. Makes the rule about as useful as "don't piss on the escalators"--no one who does it will be dissuaded by a sign.
- hombre_fatal 8y agoSounds about as popular as reading encyclopedias for fun. I bet I'd be hard pressed to find one person who genuinely reads Wikipedia as a hobby outside of the lone HNer who will claim "but I do." I just don't think underprivileged people are so desperate for entertainment that they'll browse a 1TB SD card for morsels of wisdom. Unless you meant you're going to pack it full of movies, music, and games, which actually sounds interesting.

- beqcq 8y agoHow does this compare to taking 1024 1GB SD cards and affixing them with tape?
- penagwin 8y agoYour method has a few downsides, namely: * No support for files over 1GB (videos can easily go beyond that on modern cameras) * Poor access times/latency for anything not on the current card (you have to manually swap it) * You have to use tape * Depending on the pricing, I'd be curious but my bet is that 1024 actually decent micro SD cards will cost at least 1$ a piece , and the 1TB uSD is only $449.99, so good luck finding that many cheap, and usable uSD cards.
- amelius 8y ago> No support for files over 1GB (videos can easily go beyond that on modern cameras) You can combine multiple physical drives into a single logical volume, e.g.: https://askubuntu.com/questions/7002/how-to-set-up-multiple-hard-drives-as-one-volume https://askubuntu.com/questions/7002/how-to-set-up-multiple-...
- zwieback 8y agoInside, that's how those things basically work. NAND stacked on NAND. They probably don't use tape, though.
- afandian 8y agoDepending on the tape, you could end up with some very nasty electrostatic discharge.
- CharlesColeman 8y agoThis is going to make it a bit harder to report counterfeit SD cards on Amazon. It used to be pretty easy because they often claimed to be 500GB or 1TB, and those capacities just plain didn't exist at all. Now I'll have to make an argument based on capacity and price-point when I find them.
- chrisseaton 8y ago> Now I'll have to make an argument based on capacity and price-point when I find them. You mean you're reporting them without buying them and testing them, based on what you think the capacity and price-point should be?
- wtallis 8y agoIt's perfectly reasonable to do this for egregious cases, such as if somebody is advertising something for 6¢/GB when the cheapest legitimate entry-level products are at 10¢/GB. The market for flash storage devices is efficient enough that it really is possible to know when prices are too good to be true.
- CharlesColeman 8y ago> You mean you're reporting them without buying them and testing them, based on what you think the capacity and price-point should be? Yes. If someone's offering an impossibly too good to be true deal in an area that's rife with data-destroying counterfeiting [1], they do not deserve the benefit of the doubt. This is a very well known and prevalent type of fraud. Personally, I think Amazon is negligent for not very tightly controlling the vendors that are allowed to sell SD cards on its site. They're not doing enough to keep fraud out of their store. [1] https://www.eetimes.com/document.asp?doc_id=1326059# https://www.eetimes.com/document.asp?doc_id=1326059# (from 2015, capacities have obviously changed since then): > Tests by the Counterfeit Report found that the cards will work at first, but generally speaking, buyers are purchasing what they think are cards with capacities of 32GB and up. Instead they are getting are cards with 7GB capacity. Counterfeiters simply overwrite the real memory capacity with a false capacity to match any capacity and model they print on the counterfeit packaging and card, Crosby explained. Users can’t determine the actual memory capacity of a counterfeit memory card by simply plugging it into their computer, phone, or camera. When the user hits the limit, the phony card starts overwriting files, which leads to lost data. > The Counterfeit Report often comes across cards in capacities that don’t exist in any product line, and the cards it purchases and tests that are 32GB and up are usually always fake. The counterfeiters make a great profit on the fake cards, and there’s no consequence.
- bluedino 8y agoYou could aggregate these in a credit card sized device with a SATA adapter and put what, 20TB ina 2.5” form factor?
- cptskippy 8y agoYes but why? https://www.aliexpress.com/item/10-ports-Micro-SD-TF-Memory-Card-to-SATA-SSD-Adapter-with-RAID-Quad-2/32555370970.html https://www.aliexpress.com/item/10-ports-Micro-SD-TF-Memory-...
- reaperducer 8y agoWow. That's almost exactly what I was looking for last week. I have an old machine I'd like to turn into a WORM server, but I want it to be silent and would rather re-use a bunch of old memory cards than spend money on new storage. All I could find was a device that put two MicrSD cards into a single SD card. This is even better. I'd buy it if there was a USB version, since the computer I want to re-use only has USB ports.
- izzydata 8y agoYou could put this into a 2.5" external enclosure with a usb 3.0 port.
- close04 8y agoWhy not buy a 2.5" SSD in the first place? It will be cheaper, faster, and more reliable.
- rhinoceraptor 8y agoThen throw btrfs on it, and you have a sure-fire recipe for data corruption!

- zeristor 8y agoHas anyone implemented ipfs with carrier pigeons and bluetooth memory pigeon anklets? Drones could do this, but I like the idea of using pigeons. Or just WiFi drives on rural buses that could transfer data from stop to stop. Perhaps I’ve been reading too much post apocalyptic fiction
- penagwin 8y agoI think the HAM radio operators have us covered there. On a serious note if you wanted to play around with "infrastructure breakdown tolerant" stuff, a rtl-sdr is like 30$ on amazon and it's fun to mess around with. You can tune into HAM groups, police radio, the weather, traffic control, etc. EDIT: Before others mention it, no broadcasting without knowing what you're doing! Listening is perfectly fine, but if you show up on the police scanner they might not be happy....
- zeristor 8y agoHAM radio can do this but I like the idea of a wireless postal service hitch hiking on vehicles doing their rounds. Reuter’s got its start by using carrier pigeons to bridge the gap between two telegram networks.
- reaperducer 8y agoHas anyone implemented ipfs with carrier pigeons and bluetooth memory pigeon anklets? Implemented? Not to my knowledge. But there's an old RFC from 1999 for it: https://tools.ietf.org/html/rfc2549 https://tools.ietf.org/html/rfc2549 It was even updated for IPV6, which means that it's possible to have birds communicate with a more modern protocol than many major ISPs: https://tools.ietf.org/html/rfc6214 https://tools.ietf.org/html/rfc6214

- James_Owens_69 8y agoSo will it die after 6 months of writes as they tend to do?
- logfromblammo 8y agoSo... large enough that the most important numbers on the spec sheet are now read speed and write speed.
- znpy 8y agoI was surprised no one said this earlier. These cards are big enough that at the current read/write speeds for SD card they might not be actually usable.
- Paul-ish 8y agoWe have SD Express to look forward to [1]. The bus speed of express is 985 MB/s. [1] https://en.wikipedia.org/wiki/SD_card#SD_Express https://en.wikipedia.org/wiki/SD_card#SD_Express
- afandian 8y agoOne thought experiment that blew my mind even with the first generation of solid state digital storage. Imagine an uncompressed image large enough to fill the card, at the size where you can make out every pixel, like 1mm pitch. Then imagine how small each pixel would be if you shrank it down to the size of the chip. For 1 bit monochrome, 1TB is 2828427 x 2828427. At 1mm pitch, that's is 3 square miles. Imagine shrinking that down to 5mm. (Edit in response to replies. This example is purposefully simplistic to demonstrate the point about shrinking pixels. A real photo wouldn't be monochrome, or 1-bit depth, or have a dot pitch of 1mm, or be uncompressed, or, for that matter, be 3 square miles big. I mean, who has that much ink?) Edit 2: For a 2MB Compact Flash card from 1990s the equivalent is 16 square metres. That's still a lot of pixels to squeeze into such a tiny package.
- frabert 8y agoJust an observation: 1mm pitch is awful.
- rpeden 8y agoAlways? If I'm standing 10 metres away, I don't think it would be too bad. Even at 1 metre away it would be fine. With images as large as the OP is talking about, at typical viewing distances pitch substantially larger than 1mm would be just fine.
- afandian 8y agoAwful for what? When intuitively visualising the number of pixels in a terrabyte I think it's quite good.
- Dylan16807 8y agoWhen you're trying to leverage your intuitive understanding of photos, using such a low DPI will screw up that intuition and damage the accuracy. 1mm black and white is basically a QR code. I prefer to visualize things at a reasonable density. Using boring software and a boring printer, adding in redundancy and still using very visible dots[1], you can fit over 7000 bits per square cm instead of 100. That old 2MB card turns out to only be worth 4 sheets of paper. 1TB remains enormous, but going from 3 square miles down to .1 square kilometers helps to bring things closer to understandable. With this new density it's 25 acres or 17 football fields. Considering the flash layers is also useful to my intuition. That old CF card is four pieces of paper next to each other. This new card is a box 32 meters / 105 feet on each side, filled edge to edge with densely printed dots on paper stacked 96 sheets deep. I can actually visualize that room / yard. I can visualize the dots on a sheet of paper. I cannot visualize a square mile at human scale.

- joering2 8y ago$450 for 1TB. Who else other than spies moving large volumes of data in as tiny item as possible, is going to buy them?
- Ultramanoid 8y agoMe in a couple of years. Price will fall to reasonable levels, and then further, as it has for the 200 GB and the 400 GB ones I currently use but certainly did not buy when they just came out.
- magduf 8y agoAs mentioned above, people with video cameras.

- JungleGymSam 8y agoWhy aren't these tiny cards being used in the 100s in 1U rack systems? Is there no gain from it? Perhaps even for slower medium-term storage?
- chungy 8y agoIt would be extremely cost-inefficient, as well as giving poor I/O performance.
- nicoburns 8y agoIt really is incredible how much storage you can fit in such a tiny volume. However, I think the read/write speeds are now the bottleneck on these devices. They seem to all cap out at around 100MB/s (maybe a little more if you get a premium card), which isn't very fast when your device have 1TB of storage. I'm looking forward to SD Express https://www.extremetech.com/mobile/286390-sd-association-announces-microsd-express-with-pcie-nvme-support https://www.extremetech.com/mobile/286390-sd-association-ann... which aims to solve this issue.
- freedomben 8y agoAgreed. I have tried to supplement a primary drive that is too small and I/O is definitely the bottleneck. So much so that you can't really watch HD video straight from an SD card because it will drop frames or cause other issues due to slow throughput.
- LeifCarrotson 8y agoThat depends on your use-case. The typical use for a microSD card is to store media (photos, audio, short video clips), and if you add it gradually and consume it from a managed media library, you'll have smooth sailing until you one day decide to export it or back it up and find that it takes 2.5 hours to transfer everything, assuming you don't get thermally throttled!
- int_19h 8y agoI bought a Raspberry Pi Zero W recently, and while shopping for an SD card for it, I suddenly realized that a decent 64Gb card costs more than Pi itself ($10). And then I thought about how Pi is actually a rather powerful desktop computer, by the standards of the time not so long ago. It's 1GHz CPU and 512Mb RAM - back in 2000, that would be a rather high-end PC (yes, I'm aware that CPU frequencies across architectures are apples and oranges). If you think about it in those terms, it's insane how cheap compute has become, even relative to storage.
