Itunes shows a Capacity of 57.18 GB on my ipad. I know the applications that come on the ipad take up space, but it seems like 7+ gb is a lot to take up on factory apps. Just wondering if anyone else's ipad shows the same or something different

I show 57.17 on my ATT 64GB iPad 3...I'd have to check but this is about the same capacity as my ATT64GB iPad 2, as well.

Can't give you an exact number cause I just reset and wiped all my data on my 64 GB iPad 2 prior to selling it but with all my photos and my 6 apps, I think I was down to about 56GB so your number seems reasonable to me.

my 32 came with 27 gb before putting anything on it. There are the system files, and then the difference between 1 gb in marketing speak and 1 gb in computer speak. Its normal.

My new 64gb also shows 57.17, however, my iPad 2 showed 58.1gb. I'm really not sure where all the space is going...

From Apple. But basically 1MB should mean 1000 Bytes. But because of the way computers use memory, 1MB is treated as 1024 Bytes on a computer.

32 billion bytes, in english is 32GB. 32 billion bytes to a computer is 28GB.


Capacity stated on product packaging

Storage device manufacturers measure capacity using the decimal system (base 10), so 1 gigabyte (GB) is calculated as exactly 1,000,000,000 bytes. The capacity of the storage media in your Mac (Mac OS X v10.5 or earlier), iPad, iPod, iPhone and other Apple hardware is measured using this decimal system. We set this out on our product packaging and on our website through the statement "1 GB = 1 billion bytes."

Capacity stated in Mac OS X or iOS

When you view the storage capacity of your Mac (Mac OS X v10.5 or earlier), iPod, iPhone, iPad, or other electronic devices within its operating system, the capacity is reported using the the binary system (base 2) of measurement. In binary, 1 GB is calculated as 1,073,741,824 bytes. This difference in how the decimal and binary numeral systems measure a GB is what causes a 32 GB storage device to appear as about 28 GB when detailed by its operating system, even though the storage device still has 32 billion bytes, as reported.

Nope. Let's do the math (for 64GB):
1024^3 = 1 073 741 824 Bytes in one GB.
64 "GB" = 64 000 000 000 "Bytes"
64 000 000 000 / 1 073 741 824 = 59,60...
My iPad reads 56,98 GB capacity
59,98 - 59,60 = 0,38 GB.
So, some 380 MB are lost. Error. Kernel Panic. I know it's not that much space but it is an indication that there's something else besides the marketing GB and the actual GB conversion.

Well ... it is a heck of a lot better than the Surface where if you purchased a 32GB version, you only ended up with something like 10GB (if that) for personal use.

And the higher the capacity, the higher the amount of space is "missing" such as on a 128GB iPad. On the 128GB, there is 115GB free space.

Even computer hard drives are the same way no matter if it's a Mac or windows computer.

That's supposed to be:
59.60 - 56.98 = 2.62 GB

The operating system does take some space, you know. :) At least iOS doesn't take up as much space as Windows does. :rolleyes:

This part, I actually don't get. I can understand having less space due to the disparity between binary and decimal but I don't get why system files would use significantly more space on higher capacity iPads.

128,000,000,000 / 2^30 = ~119 GB
119 - 115 = 4 GB

4 (iPad 128GB) - 2.62 (iPad 64GB) = 1.38 GB

What is that extra 1.38 GB used for?

Taken from Settings > General > About > Capacity on iPad 3 and 4's running iOS 6.1.3. Alas, I don't have a 32GB version.

iPad 4 16 GB: 13.3 GB
16,000,000,000 / 2^30 = 14.9 GB
14.9 - 13.3 = 1.6 GB

iPad 3 64 GB: 57.2 GB
64,000,000,000 / 2^30 = 59.6 GB
59.6 - 57.2 = 2.4 GB

iPad 4 128 GB: 115 GB
128,000,000,000 / 2^30 = 119.2 GB
119.2 - 115 = 4.2 GB

Applications + iOS. The actual software needs to be accounted for as well - you cannot just ignore that.
