1GB computer memory physical size in 1980 and 2009
The huge sized 1GB memory is from IBM built for mainframes in late 1970’s. The same 1GB memory comes in a micro-chip nowadays! What a wonderful technological advancement.

Really interesting to see where the next 25-50 year of tech goes.
That’s not memory it’s storage.
Indeed, yes it is storage.
I would like to point out the hand is holding a SD card. Quite a few SD cards, if you open them up actually contain a micro SD card.
Also a micro SD card can hold close to 16GB. It would have been more fair to hold a chip the size of the distal edge (white end that grows) of your fingernail up.
That truly resembles the size of 1GB in 2009. Chips that size dont tend to have a bigger capacity, but chips that small are very useful in micro electronics and onboard memory for such things as mobile phones.
Please be more accurate author.
PS: It really is unfair to compare a magnetic/tape storage device to a SSD or similar chip. A fairer test would have been comparing a 2.5″/3.5″ drive to Merlin.
Or what I presume is Merlin? That looks a lot like the storage device from a IBM 1970’s Merlin machine?
Amazing how 30 years can change things.
What will the next 30 years change
Lets hope it’s our attitude towards one another
Peace man .
What’s a ‘gigabyte’?
‘gigabyte’ is GB, you stone-age dweller!
1 giga byte = 1024 mega bytes
1 mega byte = 1024 kilo bytes
1 kilo byte = 1024 bytes
1 byte = 8 bits
bits are used to store stuff in computer memory/storage
you over anal loser trolls with your super technical bullshit is getting old. It’s a joke… laugh, who cares if it’s inaccurate, you get the freakin point.
my god i feel sorry for people who have to be around you.
krams, youve just made a troll family very happy.
their father is a huge success as of today.
krams, you’re wrong.
1 giga byte = 1000 mega bytes
…
Rhonda.
krams is right, computers don’t count in exact 1000’s
1 Gigabyte = 1024 Megabytes, and so on down to binary which is made of 1’s and 0’s.
and back to the original topic… go the over-sized ancient storage…
Rhonda, you are wrong while Krams says true- there is 1024 MBytes in 1 GByte
Actually, Krams is right. Though manufacturers and general lazy people round it to 1,000 in order to make it easier to calculate how many bytes there are. I think even windows rounds it all up to 1,000; or they may have used to. Furthermore, I also agree with “wh666″ as memory isn’t the same and disk space, maybe a little re-wording would make people happier?
No.
He was correct, 1000mb = 1gb is just what people think cause someone had simplified it.
1gb = 1024mb = 2^10
“2″ because each value in an 8bit byte is either 2 values - 0 and 1 (binary)
For example
0000110100001010010001110110010101110100001000000111100
1011011110111010101110010001000000111001101101000011010
0101110100001000000111001101110100011100100110000101101
0010110011101101000011101000010000001100010011001010110
0110011011110111001001100101001000000111100101101111011
1010100100000011000010111010001110100011001010110110101

1101111011100100111001001100101011000110111010000100000
0111001101101111011011010110010101101111011011100110010

Get your shit straight before you attempt to correct someone.
they weren’t being “anal” or “over technical,” but I suppose you’d say the same if they used terms like 800mhz ram, front end BUS, or even POP3.
If 1 giga byte is not 1000 but 1024 mega bytes, then why do we say
1 GB = 1k MB
k is 1000 and it is NOT 1024.
???
I don’t understand what Kikkoman is trying to explain with those zeros’ and ones’.
Gigabyte can mean either 1024^3 (2^30) bytes or 1000^3 (10^9) bytes. Although the computing industry has adopted the metric notations (k, M, G, T, etc), initially they used kB to refer to 1024 bytes and kb to refer to 1024 bits because the difference between the two systems is only ~2% at k. For G however the difference is ~7% and for T it is almost 10%! This is why when you format your 1 terabyte drive, it may only have 909 gigabytes.
Modern computer hardware manufacturers generally use the metric system (GB = 1000^3 bytes); probably partly because they can sell less for more. Some people use GB to refer to 1000^3 bytes and GiB to refer to 1024^3 bytes.

You ultra-nerds need to get LAID!!
Jesus fucking monkey balls…..
So which is it 1GB=1024MB or 1GB=1000MB? Me and my buddies got into this argument last year because I thought it was 1024, and they said it was 1000
Yeah, it’s all based on whichever is more convinient. Programs and most file managers base it on 1024 but it sounds better in you state it using 1000MB = 1GB to sell storage.
@David: a nerd is a socially awkward person. These people here are passionate for modern technology and are discussing things that they enjoy discussing about. By calling them “ultra-nerds” (using a computer yourself, no less) you’ve proven that:
1.- You’re more of an “ultra-nerd” than every single person posting here, combined.
2.- You have no idea what a nerd is and are just calling people names out of your ass.
3.- I’m pretty sure everyone here has got laid more times than you have or will ever have.
Please, get a clue, or do yourself and everyone a favour and choke.
I have had this fight several times, and recently gave up.
In freshman year, my TA said in class a gig is 10^9. I jumped up and said, no it is 2^30. Nobody had any idea what I was saying and why I was worked up.
Finally, everyone has surrendered. 1024 bytes, believe it or not, is now called a Kibibyte and 2^30 bytes is a Gibibyte written as GiB (check out wikipedia if you dont believe me). It is written KiB. KB is 1000 bytes now. So, GB now is 10^9 bytes, and the stupid TA must be laughing from her grave (I’m sure someone murdered her).
Just remember, as we move into TeraBytes, you are getting 91 % of what you should have when you buy a hard drive.
Interesting comparison, not quite accurate though. The drive pictured is a “Head Disk Assembly” (HDA) from an IBM 3380 Model J storage device released in 1987. The HDA is actually 2 disk drives in one, with an actuator on each side. Each actuator was 630MB, or, 1.26GB per HDA. The actual device had 2 HDA’s in it for a total of 2.52GB per unit. List price was $59K or $82K depending on whether you had a controller box or not. State of the art stuff for 1987….
Don’t be stupid! The man in the shop told me it was 1000kb to a mb. Im sure he knows his job much better than you stupid ‘pretend geeks’ who think you know so much but are really all lying to sound smart. you leave rohnda alone cos she is right.
1 GB = 1000 MB…. At least according to the SI system… I know it sounds odd but in the SI system there are rules that have to have to be equal for all measurements. Just like 1 Km = 1000 m and 1 KJ = 1000 J etc.
Both sides have a point here actually. This is because physicists work with the decimal numeral system and computers work with binary numeral system.
2^10 = 1024 and 10^3=1000… kibibyte and the magabyte.
Umm, guys. Let’s get smart here. There is a difference between the decimal prefix giga and the binary prefix giga. The decimal system uses the SI standard for the definition, where as binary uses both the IEC and JEDEC standards for the definition. Neither is right or wrong on paper. But when it comes to electronic memory and storage, the IEC and JEDEC are what is correct.
The JEDEC and IEC definitions of Giga (Gibi in IEC, actually) is 1024 cubed, or 1 073 741 824.
The SI definition of Giga is 1000^3. or 1 000 000 000.
Ever wonder why your hard drive says 500gb but only about 482 are actually available? It’s because hard drive makers use the decimal definition to make it seem like you’re getting more than you actually are. Operating systems, since they actually have to know the amount of bytes available to use, will show the binary definition.
Cloud9ine is both right and wrong, since both JEDEC and IEC are used for the binary definitions. IEC, as he’s said, is the one that’s gibi, JEDEC (the people who DO memory standards) still call it giga. Giga is right for 1024^3 in an electronic memory environment, due to the way binary works (I realize a lot of you are retarded, so I’ll just say that it has to do with a bunch of 2’s [since 2 is the number of possibilities to choose when the options are 1 or 0. Reread that before correcting me, it's right. You're just retarded.])
Giga = 1000^3 in an SI environment, which is basically everywhere that isn’t computer memory.
It’s confusing, but I think you guys can grasp it now.
very nice and informative site. I really had a great time reading some of you post.. keep it up and looking forward to read more soon.
That was a great post….I love this site. Thanks
That was a great post..I love this site. Thanks
That was a great post..I love this site. Thanks
So I’m confused… what’s the difference between GB and TB?
the difference betwn GB and TB is G & T
Who says nerds don’t get laid? I enjoy nerds immensely. I’d fuck a nerd any day of the week and I am typically repulsed by the whole muscular jock type.
great article, will recommend to friends rep
What is missing is the difference between uppercase and lower case when applying it to computer terms. k=1,000 K=1024 further both are in use and while some think they are interchangeable that is not the case.
Snobby douche bags. It would be nice to look at a picture and for once not have someone nitpick over it. Oh I found that you can Google the questions you asked and the result is that you’re not made to feel stupid when you find the answer. Have a nice day Fuckers.
fascinating forum…. But why argue between 1000MB to 1024MB, it is just the same… The question is why you can’t format the 500 GB of hard disk in full? Why there is missing bytes…Actually the manufacturer together with the software developer agreed to make that in standard because for safety features.. If you ask me why? you can research it yourself and find the answer yourself and you will see why…. ^_^ God bless you all and more power on this site it entertains me really..
You’re beeing too complex ’bout this Giga thing
True is :
K (Kilo) is 10^3 = 1000
KB (Kilobyte) is 2^10 = 1024
simple that way.
it’s 1024 just because in computers everything is manipulated in base 2 (binary) with 0’s and 1’s …
they used the Kilo, Mega, etc names because of the proximity of the numbers (1024 - 1000). And remember that this happened in the 60’s-70’s …
they can’t imagine that nowadays we’ve got this PETAbyte things !!!
sorry by my bad bad bad english …
All these posts about what Kilo and Megabytes and storage values and ones and zeroes etc etc etc… sounds like the guys from BIG BANG THEORY posting to this website…. take a chill pill, Sheldon!! ROFLMAO!
OH my. I was just googling pictures of old storage devices because I was amazed at how an iphone can have 32 GB and wondered where all those 10101010101010000111111….s go. I was never expecting to find so many wildly entertaining techies. THANK YOU. My favorite is the binary code for “get your shit straight before you attempt to correct someone.” That was great. Probably accurate too, I would never know.
Great posting. It Kinda makes you think.
