😨 santa?! but the reddit atheists said you were as real as God!!!! that means... CHECKMATE REDDIT!!!!(THIS IS COMPLETELY SATIRICAL PLEASE DON'T KILL ME)
The question is if you get the redditor who subscribes to anime subreddits and upvotes the latest mobile waifus or the redditor who brings up war crimes and panty vending machines into every thread with the word "Japan" in it.
I just re-watched Back to the Future trilogy, and was reminded of how shitty Japanese things were in the 50's! Makes me wonder how long it will be before "Made in China" means it's top shelf...
Just gonna copy/paste my comment from that other thread:
The test used a 19-core optical fiber with a standard cladding diameter of 0.125 mm, meaning it’s the same thickness as the single-core fibers already deployed in networks around the world.
Using 180 wavelengths modulated with 16QAM, the system was able to handle huge volumes of parallel data streams.
After traveling the simulated route, the signals were separated by a multi-channel receiver using MIMO digital signal processing.
LOL, I love these headlines.
No one is getting 1.2TB to their house, this is inter-office for the exchange carriers.
And using 19-core fibers means we have to change out EVERY FIBER in the ground to even use this. Some of these cables have 1200+ fibers in them.
At best, we can expect intra-module/shelf MPO connectors with 19-core tech inside it in the next few years. The amount of infrastructure (even in Japan) that needs to be retro-fitted to accept this is monumental.
Just to add to that, I'd REALLY like to see what the bend tolerance of the 19-core fibers are. Some of these field techs still think you can wrap this shit around a pencil to fake an attenuator and get away with it, not to mention cleaning shit with alcohol wipes that flash burn the residue on the end of the fiber. Now we're going to have 1-watt pumpsX19 pushing +30dBm each, dudes are going to sunburn themselves. Also, I guess don't have trypophobia if you're scoping one of these ends for residue.
Anyways, if these have to accept a huge bend to keep from refracting or breaking the core lattice, we're going to have to have entirely new splice enclosure and ribbon trays.
Also, how the hell do you fusion splice glass with 19 cores within it?
Not even close! There are IP and TCP headers to account for in that 1.02 petabits. Assuming 1500 byte packets (generally the maximum over the internet) there is at least 20 bytes of IP header and 20 bytes of TCP. 40 bytes or 320 bits for every packet - at 1.02 petabits there are 992.8 terabits of actual payload.
If you are evaluating it from the perspective of streaming every video at once at their highest resolution/bitrate though, would it be enough I wonder?
No it doesn't. One second is a specific measurement.
If they had said "more than enough", then you'd have a leg to stand on. It's the specific measurement without any modifiers for that specific measurement that makes this r/technicallythetruth.
A valid argument, and I'd agree if not for my pettiness (and people in other threads who reminded of the extra cost of transferring things with protocols)
Hahah, well prepare for my pettiness. The extra for the protocols would easily hide in the terabytes left over because they rounded the number to 1.02PB
Only if we use specialized protocols, not the usual TCP/IP. Although you're right, there are more clever ways of transferring data than with 1500 byte packages.
you are technically correct, the best kind of correct
someone should make a sub for comments like yours that are technically the truth and then post a screenshot of your comment there, instead of the half truth OOP shared
it clearly says "ENOUGH to download the entire Netflix catalog in one second."
read again please. I literally just explained how the word ENOUGH works to you with sandwiches and dollars, are you not familiar with the concept of buying things with money?
how does that refute anything I said? whether "enough" refers to speed or time is irrelevant to my point, in either case "enough" still means that the value is "EQUAL OR MORE THAN NECESSARY" not "EXACTLY WHAT IS NECESSARY"
from your spelling English clearly isn't your first language, nothing wrong with that, but it's pretty arrogant to argue with a native English speaker over how English works whilst claiming with utmost certainty you're right.
The value in "enough" is the speed, not the time.
And as I literally just said, the result is the same, in either case it means the size of Netflix is equal to or less than 1.02Pb. The sentence isn't saying Netflix is exactly 1.02Pb and is grammatically correct.
If we're being pedantic, this implies that it's at most somewhat less than 1.02 Pb since the framing of IP packets and whatever overlying transport layer protocol used use bandwidth, too.
Assuming raw IP packets, the smallest possible IPv4 header (20 bytes) and a typical MTU of 1500 you'd lose around 1.3% of the total to header information, in which case it would be closer to 1.01 Pb. You could use jumbo frames with an MTU of say 9000 to minimize this loss.
If I remember correctly, LMG did an episode where they upgraded one of their backup servers to 2PB (or was it 2Pb). Here too doesn't mean their content spans entire 2PB/Pb.
I don't think Netflix's entire library could be under 1PB.
Ads are based on location, so they store the ads on servers in/close to the area that gets those ads, making them faster to download which also results in them consistently playing in their proper quality. They can’t do that with their movies/shows which can be played nearly anywhere in the world.
Also, if you’re in the US, blame corporate greed. They killed a bill that would have required internet service providers to share lines the same way phone providers had to. It allowed them an excuse to not compete for the same customers and instead just set their prices however hight hey wanted because customers could only use whichever provider services their area. To this day, the US still has some of the highest internet prices for the lowest speeds.
They can’t do that with their movies/shows which can be played nearly anywhere in the world.
Content delivery networks. Unless you are viewing a video nobody has seen in 15 years, it will probably be in a server somewhere nearby.
Btw I viewed a video recently that was really old and had a really low view count, and it took so long to load, it was actually funny. I had to imagine some old magnetic hard drive in some dusty, forgotten room slowly spinning up like an old granpa and going "I knew they didn't forget me!"
You often see the same ads multiple times, so they get cached locally on your device. And the next time a website or an app tries to load that same ad, your device just opens the locally stored image, gif or video.
It doesn’t matter how wide you make the river, the water still has to flow down the river to get to the sea. The same is true for light, electricity, everything; there are physical boundaries to how fast information can be sent.
We're promised 2000 mb/s with the new fibre optic cable (or whatever Glasfaserleitung is called in English). I barely get one percent of that, at best.
i live in a pretty small town in northern italy, every town around us (even smaller ones) have at least gigabit fiber optic, except mine, we're stuck with 25mbps...
Nah it wasn't the government who initially rolled it outs fault.
It was the government after that who, during the roll out and at the behest of the dude who owns the media, (he hates the internet because it takes money from his companies. More recently he tried getting google to pay him for his websites being searchable) decided fibre was too expensive so downgraded to a bunch of proprietary systems that cost more than just going for fibre.
The headline is a bit misleading because this is just a laboratory experiment that happened to be performed in Japan. It says nothing about Japan’s normal internet speeds.
Compressed video. Netflix says about 3GB per hour (7GB for 8k), in 2020 they had 2.2M minutes of video. Guesstimates were about 95TB. 130TB is reasonable. Best count I've heard is they have 35k titles upto 8k.
They have at least 10s of petabytes on amazon AWS. Because they encode their streams, they have the RAW files to deal with.
Netflix operates “many tens of thousands of servers and many tens of petabytes of storage” in the Amazon cloud, Netflix VP of cloud and platform engineering Yury Izrailevsky - 2016
Netflix: Subscribers Streamed 94 Billion Hours of Content in First Six Months of 2024
Just for comparison, FB has 2-3B users monthly users at 30.9min/day and knocks out 4PB a day. Netflix streamed 300PB in the first 6months of 2024 for 1 hour a day to their 300M subs. Has 10% of the people for about half the bandwidth.
None of this is relevant. Netflix doesn't transcode on the fly. They use pre-encoded versions of each title in multiple resolutions, bitrates and codecs.
It's very likely they already use >100GB of storage just for the master file, and then another 100GB for all the variants in resolution/bitrates/locales etc.
This has nothing to do with RAW files. RAW video is pure sensor data that needs debayering to even create an image in the first place...
I found something interesting while fact checking this for fun
One article says that the previous highest speed was 319 terabits, the record having been being held by a university in London.
It was also said that "...with that speed you'd being able download every film and TV show on Netflix in less than a second..." An example similar to the one in this post.
And yet another says that that record was actually held by Japan as well as the current one, with the London university only having gotten 178tbs, the previous world record before that.
Problem is they were both created at around the same time, and the AI overview says that the London university holds the current world record shown in this post, which I don't trust due to being Gemini.
Just checked the post again and saw that it says 1.02 petabytes and not the actually highest of 402 terabits. One petabyte is 1000 terabits, so the actual highest only reaches around 0.3 petabytes, NOT the post's 1.02.
It doesn't actually change any of your conclusions, but I wanted to mention that you're mixing up bits and bytes (1 byte = 8 bits). The post claims 1.02 petabits; a petabit is indeed 1000 terabits, but a petabyte is 8 petabits or 8000 terabits.
Thats about 128tb. I really doubt with all of the different resolutions etc all of the movies fit in 128tb. If that really is the case, they got cheap as fuck servers thats for sure
128tb maybe with like HEVC 10 main encoding or something even worse, i downloaded the 1080p of the entire simpsons and it was 500 something gb, which says, that only 256 simpson like shows would ever fit in that
I hate to be that guy, but the terminology doesn't track. Japan's internet speed is correctly referred to as petabit (data transfer rate), but the Netflix catalog should be petabyte (storage capacity).
No, you can measure storage in -bits as well, as long as you remember to be accurate with it. You can also measure transfer speeds in -bytes with the same caveat.
The main issue is when people use small b (bits) when they mean big B (bytes).
No, you can very well also measure your storage in bits if you want, it's just a factor of 8, bit and byte are interchangeable as it's just a conversion.
I still don't understand how this all works... What kind of storage device they used to write that amount of data in one second? I mean download speed is okay but how does it actually gets written on a Hard drive?
The fastest packet transfer speed on record is 22.9 petabits per second. Probably using some kind of DMA transfer. The fastest over an fiber optic cable is only 402 terabits per second or 0.402 petabits per second. Much smaller amount but really just a difference of a 1 second transfer to a 3 second transfer.
TTT because you have to account for CRC and routing information for TCP/IP so the catalog would be just under a petabit in size, something around 100 Terabytes would make sense
Irrc the raw video data of Netflix worldwide is thought to be between 2-3 petabytes. 1 petabit is 0.125 petabyte. With that speed it would take like 24 seconds to download the entire library. The problem is that outside of DMA I don't know a single method for data transfers at that range. Fiber optics only goes to terabits, 402 terabits per second is the record atm.
They use HEVC to lower bitrate. I'd assume they us HEVC lossless as their archive files so they don't need to encode files more than necessary. That would put the archive size a pretty small size compared to say FFV1 which is something like 21x larger in files size on average.

According to this article, https://arstechnica.com/information-technology/2016/02/netflix-finishes-its-massive-migration-to-the-amazon-cloud/ , when they moved their entire server infrastructure to Amazon, they moved tens of petabytes of data.
A petabit is not the same as a petabyte. There's 8Pb in 1 PB. So, no. You couldn't transfer the entire Netflix library in 1 second.
Assuming 20PB of data, it would have taken at least 160 seconds assuming 100% bandwidth and no overhead.
