As always, this is a well crafted and informative show. Thanks for all of your hard work.

Been working in IT for 20 years and never realised that HDDs look for a CHANGE in magnetic field, and not just the direction of said field. Makes total sense what with the current induced/inducted into the head. Really enjoy your videos - you cover topics which are very handy to know if you are going to be making films, but are still useful even if you are not (which I ain't). Thanks.

I've learned more from this channel in one day of watching than I have in 2 years of film school. Why am I even going to college? This is free!

Could you do a video on encoding and how big production houses process all of their footage to get ready for editing? You are the most informative channel on all of KZfaq John and I respect you greatly!

This is one of the best data storage summaries I've watched. Period. Thanks for the many minutes well spent. Also, I'm sure someone has pointed out somewhere the NTFS. - 10

Thanks John. I love the background information and how it helps others understand how we got to where we're at. And I love this -- "But first, you have to get out there and make something great." -- John Hess :)

Thanks for all the hard work you put into these, John. They're always phenomenal and I always learn a lot!

At 17:41 it should have been NTFS. For the rest great video!

Thank you, a very well produced video. I need to point out something at 10:10, both lands and pits on a CD or DVD are read as zeroes, the transitions are taken as ones.

I love your videos. Probably my favourite channel on KZfaq. Great quality and delivered with real passion. Keep up the greatness!

Wow, another great video, glad to see you're back John. Thanks much, Moses...

Great to see you back! Love all your videos, please keep em coming

Nerdy nitpick: you kept saying "Ten" thousand 24 instead of "one" thousand 24...or "ten twenty-four" Just nitpicking. Great episode! (as always)

You cover a subject very very deep for helping people produce a product. Well done.

This is great info. But to add another nitpick: when current can pass through a switch, we say it is "closed", and when current cannot pass through, we say it is "open". A switch is part of an electrical circuit, and a "closed" circuit allows current to pass through it from one terminal of the voltage source to the other.

You are so great at this... You have a new very happy subscriber... And will binge watch these one day very soon...

SUCH a great video John, you are a true scholar, Sir! I doff my cap to you

You deserve a gigabyte of subscribers! Keep it coming John. Cheers!

Great video, you explained things very well. Please keep making these great videos. Thank you very much.

"Hot Electron Injection" is a good name for a band! 😀

I learn so much subconsciously through this channel.. I just turn it on I listen whiles doing other stuff

It's good to see you back, IQ

Taking about the cards used in cameras reminded me of my first digital camera that used 3.5 inch floppy disks.

Nicely done. A very thorough treatment of the topic.

what a wonderful lecture. first time I found this channel. subscribed now and look forward to watching more videos

This video confirmed to me that SSDs are magic.

First digital camera. Was a kid and me and the family were on the way to Washington, DC to tour the White House (we had an in with a high up), I was real into tech and I remember the camera took pictures at a whopping 1600x1200 onto a 16MB CF card! I made my dad buy a "large" 128MB card and I got myself a 128MB SD card for my Mp3 player. Oh how funny it is that MB's have turned into GB's in terms of whats acceptable, 16MB's was okay then and now 16GB's is just about okay now! Crazy!

You never fail to make a great episode!

OGM! I was waiting so much for a video about this topic :)

I always find myself saying "Make something great!" along with the video hahaYou guys are great thanks fore these useful videos!

7:35 dat cut though :) great video as usual, very informative.

Excellent video! Thanks!

You got to petabytes and I thought, okay he’s gonna stop. But then you kept going and GOING! I never even heard of a Yotobyte!!! Can’t imagine what sort of data will require that much storage in the future; simulations of the mind perhaps

Another great video!

Thanks John, some very intersting info there!

I really enjoyed your video on the history of data. I did spot a mistake. The MS PC OS file system is NTFS and not NTSF (as stated in the video).

Wonder-full episode!

I loved this. Why the 4 dislikes? I guess those people are still using pen and paper to store information lol.

Very well done!

The Windows Filesystem is NTFS not SF ;) Thanks for your videos! Really love them!

As always, GREAT VIDEO!!! :)

Thanks man! You save my life.

Thanks for this. Very informative

a terrabyte is what happens when you faceplant really hard on soil

Great video!

great episode! :)

5:05 And I always thought I was being screwed every time I bought a new hard drive.

thank you Mr. Hess!

Awesome video, nice info

Thanks John!

woow.. what an effort!!! ur awesome

Always entertaining and informative! The FAT32 4GB size limit and exFAT information, could help out some creators on YT.

well done!

Is there any way we can donate so you can post videos more often?

So good. Wow.

Wilhelm scream in the opening, I expected nothing less. By the way the CGI looks nice but I miss the blackboard animation style.

the best! thanks =)

nice one!

Good content.

A mod manager I have for Kerbal Space Program (CKAN) uses the base 2 or power of 1024 to give data size of files.

Great video as usual. I think I'll be wrong with this since all I find about it seems to say the same as in the video, but I'd swear that, back in college, I studied about data transmission and error correction, and I think I was told it was not the hole/no-hole what made the 1's and 0's in cd's, but the change from one level to the next that meant a 1 and no transition would mean a 0. But, I guess I'm wrong. Again, great job with this video as usual.

Awesome.

Yes, a new one

Good video. One correction: Microsoft's file system is NTFS. It would be nice to update the video to reflect Linux and Ext4 or XFS.

You forgot the nibble.... 4 bits is nibble. Great Video !!!

By the time we will have film and fotos at 18K and audio at 24channel surround at 128bits,yotabytes will be common.

Good video

At 6:29, you have Terrabyte, instead of Terabyte (more nitpickery I know, these vids are superb).

I understand that Shooting Ratio is the total duration of footage created for possible use. That 10:1 means that there’s times more shots of the actor saying “Hi” that are intended to be used. But what I’m not clear on is if that ratio takes into account multiple takes of the same angle, or if it means 10 different angles (or a combination of the two: like two angles, 5 takes each)? And also, do bad takes count towards the ratio? I mean, is 10:1 ten times USABLE footage, or just ten times the footage -regardless of how much is good/usable-?

"A Bit of History on Data". I see what you did there^^

That some amazing facts

Wonderful Video Thanks. But you made a little mistake in naming Filesystems. Its NTFS not NTSF.

Just a little correction: wherever he says "ten-thousand twenty-four" it should be "one-thousand twenty-four" because 2^10 = 1024, which is one-thousand twenty-four. I'm sure most people would never know the difference anyway :P

The title is a pun. MUST WATCH :O

Gotta have the Wilhelm in there!

how the feature length films were compressed in a smaller storage device?

very interesting

Think I'm up to around 2TB of archived footage now. I really need more storage...

thanks for clearing that 400x jargain i kept see on mc packages, it really bothered me

NICE YAAR

can u guys please do a video on codecs and different encoding?

He forgot 4 bits is a nibble(SP), because a nibble is half a byte. :)

A BIT of History on Data

But what comes after yottabyte like as in what happens when you get to 1000 what’s the name ?

What software is used here for the animations?

I still need to know how KZfaq stores all those 8 hour Nyan Cat videos in 240p alone. How many HDDs do they have to fill per day for people making 21st century facepalm kinescopes of their TVs? Also, you forgot to calculate how many Kansas City Standard cassette tapes it would take to store a raw 4k copy of The Hobbit.

The title sent me here. I was looking for a bio on the android from ST:TNG. Just kidding.

He posted the video like 15 mins ago (19:35 minute video) and you have people saying "Great video" and "Very informative" ... haha..?

@ 17:44 its NTFS not NTSF ;)

How about stacking movies all on 1TB flash drives and stacking that?

Now I know!

At 17:50 Microsoft file system is NTFS and not NTSF. Not big deal. Apple OSX lion 10.7 2010 and later actually reads NTFS without extra software. But it can't write on it. This is very useful in MacBooks with both OSX and Windows installed. On the other hand Microsoft can't read or write HFS+ The omission of Linux file system ext2 and ext3 is very serious. FAT32 would have disappeared a decade ago if SD cards and Linux devices didn't support it for compatibility reasons.

What about Memory Alpha...?

Thanks for posting. Another informative and enjoyable video. 0001111101010110101111010000101010010001001....... NTFS = New Technology File System. Yet *another* creation from Microsoft -_- Get yourself a co-editor to help spot some of these.... (if at all possible, with blonde hair, blue eyes and a sweet disposition) Noted that 'Star Trek' sound effect at 9.13 This video reminds me of that scene in Breaking Bad where they destroy the data on a laptop in a Police evidence warehouse with a giant electromagnet. Ha-ha,...that was funny. Thanks again for posting. How much time does it take to complete one of these great videos, from idea to completion?

Can you explain why most cellphones are $100 to $200 more expensive as the storage goes up, specially from 16 to 32 and 64? Is it just a marketing scheme or is there technical limitations? You don't find that price difference between sd cards.

Well done, John. I wish you would have been my instructor in 1968 in computer school! But then, you would have not been here or in diapers, eh?? ;0)

the best thing about 4 bits? it's a nibble. you can't make this stuff up.

BLURAYMASTERRACE

9:28 Was that my left bicep?

The Windows file system is "NTFS" not "NTSF", i know it's confusing but just wanted to point that out.
