- You can hold all the data in the American Library of Congress AND all the data from Wikipedia on a small stack of solid-state drives especially considering a single SSD's capacity can reach up to 30 TB of data. In this video, we'll explore how tens of terabytes can be crammed into such a small space. This technology is called 3D NAND, and specifically, we'll explore the physics and concepts on how 3 bits of information can be written to and read from individual cells.

This channel should be part of engineering course
Thanks a ton!! The hope is to indeed be integrated into engineering courses and high school science courses.
Agreed
@@BranchEducation These are some of the best videos I have ever seen!!
Agreed
@@BranchEducation if you translate your videos to Spanish I'll certainly include a lot of them in the physics course I teach
The simplicity with how this channel explains some of the most complicated topics of modern technology and still manages to leave nothing untold is astonishing. I was about to ask exactly how electrons are stored in the charge trap and immidiatly after the video points me toward the answer. This serie is a true work of art. Thanks for sharing.
Agreed, I would normally have no interest in this topic at all but I can't help but watch when it's presented this well.
Agreed! Absolutely incredible... we need this guy teaching our youth or this style at least.
Yeah, I couldn't keep up with the explanation. I believe it was all perfectly explained, but it was all techno-jibber-jabber to me. I would have to watch this 1000 times before any of it made sense.
Seriously. This guy puts a ton of effort into these videos. And the animations! Again, the animations! They're always exactly what he's talking about and showing. I wonder if he does those as well, or if that's outsourced. Either way, extremely impressive
0 . . ,
Omg, I didn't even know 30 terabyte capacity SSD already existed.
What a time to be alive!
hold on to your papers!
@@TheAnimystro you just have to wait two minutes for them
@@silverliniing Wow, thats crazy how much technology advances in such a short time. I guess I will not gonna be surprise if next year there will be flashdrive sized petabyte version of it soon.. yet here I am commenting using windows 8.1 with 32gb SSD Netbook....😪
@@silverliniing Thanks, I just bought 2 pcs. It's too expensive yet, I can only afford 2
Maximo Dakila 2?! That’s 80000USD for 200TB!
Never been this early, I am proud to be studying electronics. I learnt more in these 13 minutes compared to all my cumulative study of a week. Full patreon support to this channel when I get my job!!!
So what are you now?

Dude you destroyed my 4 years of college in just a single video.
And this video was free to watch, how much did all those worthless college books cost?
There’s less of a need for college every year. The tuition cost is exorbitant, the professors are hard to learn from, and free RUclips tutorials are easier to understand than the paid lectures. I’m not sure if I should dropout and learn on my own on my own time and risk a 4 year bachelors degree.
*College professors hate him!*
Hate seeing this comment everywhere as if a video like this was all you needed to know. It's a help, but it won't replace your hours of studying.
@@snoowwe all the knowledge is freely available but unfortunately doesn't really look great on a resume
I studied electronic engineering my whole life, and I have never seen such an incredible demonstration ... congratulations for the work done on this channel
Well said!
This is the most detailed and most illustrated explanation ever.
Thank you for the wonderful work you have done to explain everything in a simple and illustrative way
Probably the best educational channel on electronics, engineering and technology. Keep it up!
I learn more in this one video than my entire electronics engineering course
The way this channel explained all the concepts are fabulous..this is the way colleges should teach.
I'm so glad you got sponsored, this is a great recognition of your awesome work!
Thank you so much!
I can't convey just how wonderfully clear this video made this topic for me, the animations and diagrams are excellent and the narration was perfect, explaining everything step by step, with nothing in between left unexplained for me to ponder. Thank you and well done!
Ssd are getting better and better
Indeed, the ability to store exabytes of memes draws near.
@ yes i think their will come a time when SSD's will need a large cache of faster more durable cells at this rate. Tbh tho i think SSD's are fast enough for most things right now, and RAID exists for anyone who really really needs the fastest speeds.
@ well it's not like they are getting slower, just means you might not be able to read dozens of gigs a second off a single SSD without making some compromises if they can't. That said I think we are further from the limits of memory technology than CPU's, it just might take a fundamentally new approach to memory storage.
And slower and slower, relatively. Those levels of voltage leads to slower performance as opposed to single voltage cells
I have seen you comment in 12 of the video's I have watched lately...
I absolutely love this channel. I'm sure a lot of work goes into the animations and I just wanted to say thank you. Y'all are appreciated!
I love this channel so much. Everytime an explanation brings up a new question, it is answerd right after. This type of teaching is extremely impressive.
I am waiting for the video for a long time ,thank you so much BRANCH EDUCATION to provinding us a amazing concept through 3d animation .
LOVE YOU
I was always wondering how TLC flash works and what that means exactly. Really glad RUclips recommended me this channel.
One of the most underrated channels on youtube. 300k views only? That's very unfair
Thank you for this unmatched quality of educational video. I don't think there is any other channel that comes this close to illustrating this simply and with this much sufficiency.
But please make lots and lots of videos. There are only few.
The quality of this content is astounding. Such high quality visualisations and explanations. A truly excellent job. Hats off to the creators.
The level of information here is just insane, yet illustrated and broken down in such an easy way to understand! Going to go find your Patreon stat.
First time I don't skip an ad within the video. Great job at making your sponsor actually relevant
Thank you for these quality education videos! The research, credibility and production quality of these 3D models is very high! You deserve so much more subscribes!
This also makes it very intuitive to understand why QLC, TLC and MLC can't physically be as fast as SLC.
Absolutely amazing channel! HUGE thanks to the creator for all the diligence going into creating these videos.
These videos are awesome. Not too fast, well versed. May have missing information by any chance but I don't care that much, the whole thought is there for an average person to understand. Kudos
This is so incredible. Not only the content and explanation but the quality of animation too!
The technical details of this videos dramatically increased, add to it beautiful graphics and you just got a brilliant piece of art.
Now I just wonder how these tiny and complex cells are built.
this is future hahahah
Aliens
@@ikramramli6410 OMG IT'S BEEN ALIENS ALL ALONG I'LL POST THIS ON MY CONSPIRACY FACEBOOK GROUP
(I'm jk)
I’ve been looking for this comment
Very carefully... lol 🤣
thank you for this video, amazing to have someone doing this, most ppl just care about performance but some of us want to know in which way it achieves performance
Outstanding stuff! This is the only RUclips channel I like the most...
Man this is some the hands down best explanations I have ever seen
Mind blown by the technology and the animations. Thank you.
Lovin the recap section. This channel provides information better than a school
Thanks for the vivid information about display and memorisation of information in cell phone.It is clear to me.❤
I am really grateful for being in this timeline, People who understand the complexity would agree
Fantastic series, I hope your other videos are just as great but this series alone has easily earned a sub from me.
Great job at explaining this in a way someone like me (ie not an engineering student) can understand without making it super basic.
Thanks for your content
Oh shit this channel is gold! These high quality animations, narrations and education right here.
I appreciate your work 👌
This channel is so damn great, learning stuff has never felt so effortless. Very good job as always, keep going :)
Absolutely amazing explanation, intuitively done! Kudos to team
I really respect you for doing magnificent and easy to understand videos. I hope you keep up, these videos are so educational.
Thanks for including the detailed comments, they are vastly appropriated.
What a stunningly excellent and eloquent explanation for NAND. I’ve read the details but I never really thought “how does it function-physically?” Thank you very much! Sub’d.
You're Awesome Sir. You explained it better then anyone else could.
That Kioxia comparison at the 9-minute mark was the incredibly effective advertising for a product.
This is a very good engineering education channel! A must for everyone following current technologies.
Finally.. I now understand where the theoretical Solid State Physics class is applied. Thank you so much. Can't wait to share this and rest of the series.
this excellent visualisation!, having been in flash industry for last 9 years, this is the first time am seeing such !
This channel is a gem for tech lovers
Awesome! contents are amazing. Can't explain how happy I am after seeing this video about NAND internal mechanisms. Great work!
It's so complicated yet it all makes sense. Mind blown.
Superb Video!! These things are really black box for many of Engineers!!
This is really good explained, for getting the main idea! Thank you for sharing! 😀👍
Very good video. Logical progression, clear explanations.
This is jsut such a great chanllenge! Thanks for making learnung fun even at 1am...
Thanks a lot for the highly quality video. I learned a lot from it. Looking forward to the manufacturing process of the 3D NAND.
Another amazing animation and great explanation!
Sir, I am very Happy after seeing your Video. Its So Beautiful. Not one video, yours all videos in 3d view its a magic...
Wonderful explanation ....Really u r videos makes people intelligent ...
Thanks a lot for all the animations!💕🌟
Thank you a lot, very clear to understand and beautiful to watch thank to your awesome animation design. 👍
Very nice explaination, understandable.
Amazing. The comments are huge level up for the explanations
You deserve a million subs..the content you are making is marvellous..😍
I have learn so much from this videos, this is so interesting learning bout this.
Thisss is true teaching. Thank you
your animations are way better than reality …..awesome job . May god bless you for the educational information you are sharing with your domain of expertise in video editing and theoretical knowledge. Love from India ..!!!!!
Thank you so much. Very useful!
I love your explanation and video images.
The visuals here are just crazy cool
The fact that people even designed this technology is so remarkable to me
This channel is Gold!
Enjoyed Watching your Video & Got Idea how SSD Works.... Thank You Sir.
Jeez the animation here is just incredible.
So detaild and easy to understand at the same time! I would live to see similarly excellent videos about CPUs or GPUs.
Thank you for the nice Explanation
EXCEPTIONAL LEVEL OF ANIMATION AND CONTENT...BEST EVER SEEN.....💖
I've learnt so much complex stuff from your channel in the simplest ways... thanks alot.Your work is great.
Happy to hear that!
@@BranchEducation how do you get the presentation or the visualisation?
@@garethkipkoech its animated in Blender
wow Bravo for this detailed video 👏
God damn... This whole concept is BIG BRAIN!!
Such high quality materials, I wish I had this when in undergrad
this is the work of pure art
that arbitrary bit pattern you show in the captions is quite fascinating.
Great work 🥳 Thank you 💜
Fantastic video btw! I would love if you did a video on how a traditional platter hard drive works at this level and maybe include how storage density has evolved on this medium. Nice work!
I'm so amazed to the way this technology works. It`s incredible how far we can go, makes me fell hopefully about our specie, regardless the way things are nowadays.Also wanna say that the explanation makes it easy to understand.This channel is awesome , congratulations
This is really great and you are working hard to make these videos.
I really like the detail of information and the good to understand explanations on this channel. As I’m an it administrator and mostly know those things I often point colleagues to your videos because I could not explain such things better then you do.
Much appreciated!
This is very good information this channel
This is so cool! It's crazy how we can manufacture electronics that are measurable by the atomic scale. It makes me think that connectors on the motherboard (like the SATA and PCIE ports) will shrink once technology grows smaller and smaller.
This content is freaking bomb! Thank you so much!
Wonderful video thanks
wow
thanks you help me with my computer science!
Very cool and well illustrated 😎👍, very well done 👏
Excellent explanation
Awesome content mam
Hats off..
I had so many questions about what a page is, how a cell can store more than 2 values, how does it even work to have all your gates sharing an input, how can multiple cells be read in parallel. This video answered all my questions.
Hello friend! It's pleasure to see your channel growing very fast. You deserve it.😊😊
Thanks! Much appreciated
very informative - glad i found this channel - you have a new subscriber
Very useful! Thanks Branch Education and Kioxia. Btw, the animator did a good job in showing those massive caps on the enterprise version (as opposed to the consumer version which probably lacks these :P ).
Haha- yeah! they do have pretty good size caps on them.
@@BranchEducation Dear Sir; Thanks for all these videos.please upload more videos regarding NAND Flash starting from ground level to high level.
