questionswhy does my 64gb ipad not show 64gb of memory?

All that cool stuff that makes your pad work and do what you want it to? That.


If your 64GB iPad had 64GB of free space, all you would have is a very expensive serving tray.


It is an Ipad and you're complaining???
Tsk, tsk, someone take that away from him, he is not worthy.....


@rustybender: Or a cutting board you could give to your grandpa.


It's the same deal for any device that you're going to buy, whether that's a tablet or a memory card. It's 64GB total, with some of that taken up by really low-level stuff that you'll never worry about.


@rustybender: Think about it. Do iT yourself iPads! We could finally put on our own firmware and get all the support we want and unlock the true power of the iPad!


I don't mean this to sound snarky, but is this the first time you bought a computer, hard drive, flash drive, memory card, etc and checked this? If not, you'd know that the "advertised size" and the "usable size" are never quite the same.


I wouldn't think that formatting and a mobile OS would take up 6+ gigs of space. That seems like it would be crazily bloated! Here is my assumption: Hard drive manufacturers (and some OSs) have forever said that 1 megabyte is 1000 kilobytes, 1 gigabyte is 1000 megabytes, and so on. However, Windows (and some other OSs & software) recognize those values as 1=1024. This discrepancy adds up as sizes become larger. To make it easy, I found some calculations that say at the kilobyte level you lose 2.4%, megabyte level you lose 4.8%, gigabyte you lose 7.2%, and at the terabyte level you lose 9.6% of the advertised capacity due to these calculation differences. So, in this case, 64*.928=59.392. 59.392-57.17=2.222, which seems like a much more reasonable amount to be chalked up to formatting and OS reserved space. Of course, I could be completely wrong, but this is my assumption based on past experience.


Okay, there is quite a bit of misunderstanding with the way that GB is calculated. From a user stand point, 1000B=1KB, 1000KB=1MB, and 1000MB=1GB.

However, it's actually 1024B=1KB, 1024KB=1MB, and 1024MB=1GB.

So, your Ipad is actually computing the real amount of memory, not the amount deemed by the basic method.

So, you actually have 64,000,000,000 Bites of Memory. Now, for argument's sake, let's do the math.

64,000,000,000B/1024B = 62,500,000KB

62,500,000KB/1024KB = 61035.15625MB

61035.15625MB/1024MB = 59.60464477539063GB

So, you end up with 59.6GB of actual space on a 64GB drive.

Once the manufacturer installs their software (which does take up space), you get what's left.

The end.


The 2 posts above mine are correct + any apps you have installed take up space and pictures, videos, music and app data all take up space. All those pretty wallpapers that Apple has included take up space. The higher the resolution, the bigger the file size of the picture. So, I hope you have more clarity now. You still have plenty of space left and can install tons of apps, take tons of pictures, and have lots of music on your iPad. One thing that will take up a lot of memory is HD videos.


There's a bit of misinformation in above posts, and in the OP; the 64GB referred to by advertising, the box, etc. refers to STORAGE SPACE, not memory! You have 64GB for music, movies, apps, etc. Memory is used to store temporary data while a process is running. The iPad 3, which I believe is the 64GB model, has 1GB of RAM (Random Access Memory).

Now that that's cleared up, as @capguncowboy said, 64GB is not actually sixty-four billion bytes of space. Moreover, as others have said, formatting takes some space, as does the Operating System (iOS) and Out-of-Box apps (Safari, Mail, iTunes, etc.). Fret not, you did not receive a defective product =)


There is actually a standard to differentiate between the whole 1024k vs 1000k = 1GB

The hardware is correct in advertising you have 64GB but the software should be displaying either 64GB or ~59.6GiB

If you used the prefixes of "kilo" and "giga" in any context outside of computing you would be talking about powers of 10 why is computing so different? In the early days of computing the difference was slight but as computers continue to evolve the differences between the binary and decimal scales becomes more and more noticeable.
