Is there any denser portable storage format, volume-wise?

Or, to put it another, way, is there anything else that can beat:
* 1e17 byte/m^3
* 0.01mL/GB
* 10 mL/TB
* 478 GB/teaspoon
* 367 TB/gal
...?

I'd actually been disappointed that they didn't come in larger sizes. As of current, 16GB is the largest size you can get in a MicroSD. And even then, they're really slow (class 2). I'd find it mighty useful to have a class 6 32GB MicroSD for my phone. But, alas, technology has yet to progress that far.

I find it rather funny when they use "DVD quality video" and xvid compression as some sort of baseline measurement for recording your life. With the increase in storage, 1080p is a lot more feasible, and truer to life. Well, it'll get better in the future, but it'll also take up more space, plus to truly record daily life would take a much wider recording lens. Only goes to show, doesn't it?

I dunno about you, but after this comic I'll never think of the phrase, "scholastic aid" in quite the same way. I wonder if Military Commanders have the same thoughts about Martial Aids?

I do admit that I find libraries vaguely arousing: disciplinarians demanding strict adherence to the rules and enforcing quiet from those supplicants requesting their services -- many of the promised goods being dressed in leather -- presenting a somewhat initially intimidating image. At least, until you get past their card catalog and master the Dewey decimal system, turning them into your willing servant...

And now all I can think of is Wikipedia lounging against a corner lightpole, Google links exposed to all, asking passerby whether they're looking for a good time.

The first flash memory card I ever bought was for a junky RCA k@zoo mp3 player in, I think, 2002. It had 32MB of internal storage, so I got a 64MB MultimediaCard for $60 back when $1/MB was a decent price. I recently bought a 16GB microSDHC for just shy of $45. That's 256x the storage for 75% of the price. At the 2002-ish rate of ~$0.94 per MB, that card would cost over $15K.

They do make class 4 cards as high as 16GB; you just have to pay a lot more for them.

I think about this every time I see my micro SD card. I ask people on my residence floor if it freaks weirds them right the fuck out that we have such massive storage densities, but they just don't think that way... the first memory device of my own was a 256 MB Lexar Media Jumpdrive... And I remember thinking 256 MB was awesome. At the moment, i have a 16GB flash drive, and comparing that to the fact of 16GB microSD cards is weird.

On another note, my dad cam across a couple.. 8 or so MB (maybe up to 64, I'm sure its less though...) SD Cards, and I was fascinated. Such small amounts of storage for an SD card...

From the T. Pratchett Wiki:

"The Unseen Library is the most famously magical of the Unseen buildings. However, it should be noted that the fact that it houses books is the main reason that it is magical and dangerous. The additional fact that some of the books are about magic spells, written by wizards, is only a small enhancement of the magical dangers of the Library. Books contain knowledge, and knowledge equals power, which according to the laws of physics can be converted to energy and matter, so the Library contains an extremely large mass that can distort time and space. That is the natural philosophy mumbo-jumbo explanation on the dangers of the Library...."

I've always liked the idea that there is some relationship between mass, energy, and raw information. We have the relationship between the first two (E = mc^2). But what is the equation relating the second and third?

What's worse (or better?) is that it keeps on growing, storage devices are still getting smaller and denser and it probably won't stop until it's infinitely both.

First flash was for a camera and was 32Mb. For a birthday, my wife bought me a 1Gb card (large for the time). It was like getting a cheat code for unlimited ammo - forget what quality setting and shoot everything just in case. I have the $30 Lithium battery aircraft issue - I have a hard time not buying 4Gb and up storage devices under $20. Not that I need them, it's just.. so inexpensive.

Time for a bit of one-downmanship.

First memory card? TWO MEGABYTES. Smartmedia, supplied with the first digital camera I ever saw, a big-ass 1.3 megapixel Fuji with picture quality best described as "appalingly crap", which my mother's workplace (special school) bought for about £700. It *would* have been vaguely better than using a floppy-based Mavica, if the only available method of retrieving the images wasn't to hook up the camera to the PC using a serial cable. That's right. Not parallel (with USB not yet invented), but RS232 at a screaming data rate of 115kbit/s, when it felt like it. 57 or 38kbit quite a bit more often. The upgrade choice was between spending £50 on a Flashpath floppy drive adaptor (put SM into FP, put FP into FDD, run special driver, retrieve images at a blinding 500kbit or so), or £100 on an 8mb card. Although even 2mb takes quite a long time to download at 57k, they made the wise choice and sprang for the bigger card. I did a lot of my advanced-level coursework with that baby, and ended up inheriting the memory cards sometime later when I bought a far superior A200 for about £195... with a 16mb card thrown in, and crucially, a USB 1.1 connection.

Halycon days, my friends.
The biggest Smartmedia I bought was the max, a 128mb one. It was barely enough, even in late 2003. A group trip to france was an orgy of card-swapping, and in the quieter moments, making tough decisions on which images to scrap or down-rez.

You ALWAYS need more storage.
I'm up to two seperate 1Tb drives now (both external USB, but being used in a sort of manual RAID fashion to spread the risk of loss after I learnt a harsh lesson in data security ... STILL haven't got all the backups restored to them, two weeks post-purchase), plus the 120Gb in the laptop and scattered smaller amounts everywhere. And they're both less than half full right now, but that won't last long. I got a FOUR GIGABYTE (check it: 2000x larger than that first smartmedia) SD card, full size, for my current camera.... for less than £10. As per previous posters, this has more storage than any of my first 3 PC drives; Easily more so than the first two AND the entire software library of my previous Atari system combined. It should hopefully fill up less often than my 2Gb card, though that usually managed to last the course of a trip if I dropped from 8mpx to 6, and superfine to fine compression. Unfortunately, I've now loaded CHDK onto it after seeing Randall mention it :-/ .... so my future is going to be filled with HDR bracketing shots and RAW files :D :D
There's always something else that will take more space. You always need more storage, unless you're going to be aggressive with the deleting. My personal photo archive, once I've pulled it all back together, will probably amount to half a terabyte. I could go thru and kill the bad shots, but that takes a bit more time than simply selecting the good ones to upload or print.

But how cheap are MicroSDs considering the level of tech in them? My phone came BUNDLED with a 4Gb µSD. That's one card I haven't yet managed to fill thanks to the small filesizes of current mobiles, but it's probably a blip.
But, 4 billion characters of storage. The size of a pinky fingernail. Effectively FREE. Or maybe the price of a cheap non-fastfood dinner out for two, if bought.
Damn.

What we really need is the transfer speeds to go up, up, up, however. My tera drives max at about 20mb/s, which isn't so bad considering they were dirt cheap (under £60 each) whilst still being reliable big-name branded and they use USB. It does mean that a complete fill - or backup - takes at LEAST 14 hours. USB3 will help, and using SATA-III for internal disks, but still... it's a far cry from old HDDs of under a gig that still managed 1-2mb/s. (Or even the 40gb drives that I backed up to the teras, at about an hour each).
And a general move to solid-state, such as the SD cards. You can pack the devices down much smaller, which helps with making them more robust (can pack more cushioning around them without being too bulky, and hold them more firmly), and they're less susceptible to common modes of damage such as shock. In the other room we have a user's external 250gb pocket disk being given a thorough Spinrite'ing after they dropped it. So far megs 0 thru 224 are generally bad... a non-fatal head crash has still caused SO much instantaneous wreckage, because all that data is contained within a sub-1mm wide ring on the disk.

I feel old... My first memory card (A MultiMediaCard) was around y2k and it was 16MB...

About the question of who needs that amount of storage...
I have a Nikon D40 (6MP) that photos in the fine compression are about 4MB a photo...
I can take about 4000 photos on a 16GB card, if I go on a two week trip, I might use up that storage, especially considering there were times I've taken 500 photos an evening.

Less than 300,000,000 16 GiB cards could hold the Internet. (500 XiB / 16 GiB ~= 3 * 10 ^ 8)

That's quite a few soda cans.

Postby tahrey » Wed Jan 20, 2010 2:13 pm UTC

^^^ Also I'm doing my damnest to force echochamber to upgrade to a bigger disk.

What I originally wanted to do was run the maths on floppies vs 16gb micro SD vs iTunes.

One floppy disk = 1.39Mb... assuming the typical 3.5", high density, MSDOS formatted type.
One "16Gb" µSD card = about 15,999Mb
One iTunes = ?!?!?!

We could also for the sake of this exercise presume a 3.5" disk (or 5.25, or 8) is like a really huge, slow, low capacity memory card, or a microSD is a very small, fast, dense floppy :D Doesn't affect the numbers any but it's nice to give your imagination a workout.

15,999 / 1.39 = 11,510 floppies per microSD. Call it 11,000 at the very most because of memory cards tending towards fairly large sectors (upto 32kb), and floppies having 512-byte ones.

Each floppy is 90mm on a side and about 2.5mm thick...... giving us a single line 27.5m long. Or a column 45cm (1' 6") on a side, 1.1m high (3' 7.5"), which with a bit of rearrangement would fit into a fridge quite well. Munroe has done his maths here, at least. It would also take you approximately two weeks to read all the data off them onto the microSD, assuming no errors (on 11000 floppies? hahahahahahaha!) and the occasional toilet break but very little sleep.

The µSD in my phone is unbelievably small. I can imagine they would pack into a drinks can quite nicely, and in great number. Someone fetch me a ruler, a standard 330ml / 12oz coke can, and a scientific calculator.
OK, I couldn't find any of those, but I'm going to try some extrapolation. The example card in front of me fits almost exactly 6 x 7.5 x 4 (=45) times into the space of the example floppy I dug out of my desk drawer. Giving us, incidentally, a data density increase of nearly HALF A MILLION TIMES.
The can holds 330ml of liquid and a bit of air. Take a bit off for packing inefficiency, make it 300ml. The floppy has a volume of approx 20ml (9 x 9 x 0.25, rounded), so you get 15 of them to a coke can if roughly chopped. The memory card (equivalent to a piece of roughly chopped disc) will fit into the can 15 x 45 = 675 times.

675 x 15,999mb = 10,799,325mb = 10,546Gb = 10.3Tb ... call it ten teras, for the hell of it. Or about what the geocities rescue project generated. In one coke can. It's also significantly more dense than current hard disk technology, if also incredibly more expensive (675 x £10 is still £6750... or £675 per tera of course).
I'd hope iTunes is smaller than geocities was, but who knows.

Assuming a four minute song at 256kbit (the quality of download services has increased immensely since whoever it was complaining about it last used them, I think - Amazon also defaults to practically-transparent-settings VBR or 256kbit CBR, whichever is lower), that's approx 8mb per track.

10799325 / 8 = 1,349,915 tracks.

How many does iTunes claim to have? Well.. they don't, other than saying it's thousands in every category, which even my own collection satisfies. Amazon claims "Millions" however, which we must take to mean at least 2,000,001. Plus both services offer Audiobooks on top, and iTunes also has Movies and TV shows (which will use LOTS more data - a 720p mp4 video will consume over 1Gb/hour, meaning you'll only get about 6-700 typical films per tera, not even enough to cover a book of "films to see before you die" which only includes the 5* and interesting cult films instead of all the trash a download service will also have).

So it's maybe pushing it to say we can get all of iTunes in a coke can - but certainly, a well designed drinks can SSD, retailing for about ten grand, could satisfy joe average's media storage needs for quite a few years.

And a fridge full of those cans would make every download service on the planet quake in its boots.

Now, an exercise or two for the reader...
How long would it take to download that coke can from itunes, and how much would it cost?
And if floppies were cans, how long would it take you to drink the data equivalent of a fridge full of cans full of micro SDs?

PS more scariness, thanks to the "the thread has changed" warning: I've crammed at least 220 CDRs full of MP3s (each disk holding 10+ albums and plenty of miscellaneous orphans) onto my 1-tera drive. It's barely touched the sides. Maybe 150Gb in total (it used to be over 160, but the CDRs are degrading). It pales in comparison to a set my dad was given by a guy at work to take his pick from - 350 DVDRs. Bloody hell. Quite possibly more music than you could realistically listen to in a lifetime (the mind boggles at how much bandwidth he has available). But in 5 years time, that'll be but a fragment of a typical hard drive.
And my phone has about as much music in AAC on its minuscule, half-full card as my younger self had in a bulky 10-disk starter rack back in the day.

Yes I did register just to post this. I decided to crunch some rough numbers to see what'd come out.

The volume of a microSD card is 165 cubic mm or 0.165 millilitres. The volume of a standard US soda can is 355ml. This means (going on the unlikely assumption that all the cards fit in perfectly and leave no space) a can holds 2151.5 microSD cards. As the text mentions "that card" which is 16 GB this means the can would hold 34424GB or alternatively 33.6TB of storage. According to a quick google an article on Mashable ([mashable.com]) estimates the total size of the itunes music catalogue at 47.6TB, about 14TB more than the can would hold. Of course this is all estimated and assumptions have been made (that tip the balance both ways) but I think it's a large enough difference.

That said if it were a 32GB microSD it'd evaluate to 67.2TB which would probably be enough.

My first thought when reading the title-text was, “Is porosity taken into account when filling the carton and can, or is it simply the volume of one floppy/card multiplied?” I see I’m not the only one to think of that.

Additionally, this comic made me think of Feynman’s talk, There’s Plenty of Room at the Bottom. In 1959, he explained what it would take to write the entire 24 volumes of the Encyclopedia Brittanica on the head of a pin:

"Let's see what would be involved. The head of a pin is a sixteenth of an inch across. If you magnify it by 25,000 diameters, the area of the head of the pin is then equal to the area of all the pages of the Encyclopaedia Brittanica. Therefore, all it is necessary to do is to reduce in size all the writing in the Encyclopaedia by 25,000 times. Is that possible? The resolving power of the eye is about 1/120 of an inch---that is roughly the diameter of one of the little dots on the fine half-tone reproductions in the Encyclopaedia. This, when you demagnify it by 25,000 times, is still 80 angstroms in diameter---32 atoms across, in an ordinary metal. In other words, one of those dots still would contain in its area 1,000 atoms. So, each dot can easily be adjusted in size as required by the photoengraving, and there is no question that there is enough room on the head of a pin to put all of the Encyclopaedia Brittanica."

He goes on to discuss storing “all the volumes of interest in the world” on an area of 3 square yards. The lecture is pretty interesting, especially given the date he gave it and the current work in nanotechnology.

Personal note- I’ve been reading xkcd for a while and this is my first time posting to the forum. I’m pretty happy I got to reference Feynman, even if I am part of science’s collective crush on the guy [ref. “Nash” title-text]. Is now an appropriate time to yell, “Randall get out of my head” or would “Feynman get out of my head” be more appropriate?

When I was in college back in the mid-80's, one of my classmates brought in a nametag his father got at an IBM convention, and glued to the tag was a (failed) 1 MB memory chip that would have been part of a larger memory module. We spent the next couple of hours staring at it and just repeating "...a meg" over and over again.

For context, a 100 MB HDD was selling for well over US$1000, and most PCs hadn't broken the 640 KB barrier yet.

I can't even conceive of what these beasties hold. I feel like one of my old bosses who remarked, "I can remember a time where there wasn't enough magnetic media in the world to store more than a terabyte."

First hard drive: 40MB, in a Mac SE. We named it the "Monster Drive"; who could fill that? A few years later, I remember being suitably impressed when a friend bragged to me that he had a whole gigabyte of pirated software. (On tape, of course! No mortal could afford that much hard drive space!) Still later, I got a 128MB CF card for my Palm Pilot and was amazed at how much reference material I could carry around.

Today, my camcorder has a 32GB solid-state drive and a 16GB SDHC card in it. (It has enough space that it actually comes with video editing software stored on the camera so you can install it on any computer you plug it into.)

With my father's camera, there came a 16MB MMC card. I literally have no idea what to do with that little storage. I tried to use it in my kid's toy camera, but it requires SD, not MMC - the camera became unusably slow while the card was inserted. I suppose I could back up some of my prose on it... but that's about it.

Yeah, I just about did that too. So small, and yet that much space. And they have bigger capacities than that, I just didn't need that much room (I don't even come close to using all of the 2 GB I have available). And yet, I can still go over to my closet right now and pull out an old hard drive that has around 8 GB of storage space if I remember properly (might just be 8 MB). Man, we've come a long way.

TL;DR (the rest of the thread)

No, he shouldn't be freaking out at a single card.

That's just a bookshelf.

He should freak out at a soda can of them. Preferably, a soda can of them actually containing said iTunes "library".

Better yet, show him a shoebox of them containing the entire text, audio, and video contents of the Library of Congress.

Yeah, the thing is even though our storage space has evolved what we use it for has grown with it. With the advent of high definition media, the growing size of software (though I believe software size, with games maybe being an exception, isn't quite matching the growth rate of media) combined with the rate at which we can accumulate data (e.g. faster internet) means that we still have a need for ever increasing storage capacities. As such storage we found incredible at the time has quickly devolved into being almost useless because it's not suitable for storing the content of the present.

quote="LeeTheMan"]My first thought when reading the title-text was, “Is porosity taken into account when filling the carton and can, or is it simply the volume of one floppy/card multiplied?” I see I’m not the only one to think of that.[/quote]

I decided to ignore it as a factor when I was working the problem. It was only meant to be a quick and rough solution so I didn't fret over the finer details. The shape of microSD's and the shape of a soda can would work against fitting that many in certainly and would likely shave a few hundred off the total. Plus the size of the iTunes catalogue is only a rough estimate dug from that article which calculates it using an estimated song size of 5MB. And of course there's going to be larger and smaller file sizes.

Either way I think they're reasonable enough estimates that you couldn't do it with a can full of 16GB microSDs but 32GB might just cut it.

Actually that card is way more than a bookshelf. The average size of an ebook is something like 368kb. That means that a 16GB microSD could hold about 45,000 books which is probably a lot more than most average libraries.

I bought a 2 GB microSD card recently to use in one of those homebrew game cartridge things. It was a very unnerving experience.

After this comic I went onto Amazon to see where flash drives were.

Although it costs a bit, there are 128 GB flash drives available.

128 GBs... in a flash drive.



Must.... not.... impulse... buy.

Or, to put it another, way, is there anything else that can beat:
* 1e17 byte/m^3
* 0.01mL/GB
* 10 mL/TB
* 478 GB/teaspoon
* 367 TB/gal
...?


Not hugely portable, but the highest bit denisity I can find is this: http://news-service.stanford.edu/news/2009/january28/small-012809.html at approximately 3 Exabytes/in^2. I don't know how this would translate to volume.

You kids with your crazy flash drive stories. When I think about storage density, my mind goes back to my first hard drive. It was a 10 Mb full-height 5.25 in behemoth. It was still relatively huge, since the only other media in that system were 360k 5.25 floppies. If you want to talk first flash device, I was a late adopter, I think my first one was actually a 64mb USB flash i was given as a promo. Of course now, I have a zoo of different formats, microSD, SD, CF, USB stick, etc. But nothing beats that old monster hard drive. When that thing was really old, it started to fail, and the storage was so sparse, I would find files that were in the bad sectors and just rename them to xx.bad and keep on going. I think it had like 4 platters, and one of the heads had gone, but I used it that way for like 6 months. Fun times, indeed.

This is more interesting though, and much farther into the future.

I find it rather funny when they use "DVD quality video" and xvid compression as some sort of baseline measurement for recording your life. With the increase in storage, 1080p is a lot more feasible, and truer to life. Well, it'll get better in the future, but it'll also take up more space, plus to truly record daily life would take a much wider recording lens. Only goes to show, doesn't it?


You reminded me of an article I read a long time ago about data storage and "where will it all end?", read it here: http://www.americanscientist.org/issues ... -territory

This.

The card in my Reader is just 2gb and is about a quarter full. I have nearly 1,000 books on there. Text files are dinky! There is something incredibly strange (when I let myself think about it) about having an entire library traveling around with me in my purse.

My initial estimates matched Randell's almost exactly: 12 oz -> 35.5TB. iTunes claims 7 million songs. I guess ~5MB each. Thus, at 35 TB, iTunes could fit in a Soda can.

Hmm.. my first pendrive was 32mb.
Despite being young (<18), I positively feel like and old-timer constantly marvelling at how far technology seems to have come in just a few years.

On a related note, I *hate* hard drives. They seem like a great big kludge that's accidentally lasted for a couple of decades: think about it- in order to store data, you need to make a platter spin unimaginably fast, and touch it thousands of times a second with an ultra-fragile pointed stick, and if anything gets knocked slightly you lose *all* your data. A wondrous bit or engineering, sure, but horrible to maintain in general.
Solid-state FTW. (should be cheap enough to replace all hard drives within 4 years)
