Comparing the iPhone 7 32GB and 128GB: Which one you should opt for?

Hello all! Today I’ll be providing you’ll with the difference between the two iPhone 7 models mainly 32GB and 128GB (not considered 258GB, but will give an overview about that variant as well). As many of us are usually confused based on the storage of the device, this article which is limited to iPhone will give you an idea on which one you should buy?

This article is requested by one of our amazing readers, Anand Mistry. As he was confused on which iPhone he should buy, he has requested TechnoITWorld for the same. So there you go Anand, a detailed difference between the two iPhone 7 models i.e. 32GB and 128GB (as requested by you). Of course before talking about the device, I’ll be roughly giving an idea on their tech features and design and then a comparison between the two variants.

With the growing amount of data in terms of quality and quantity, it is very important for any device to have a good amount of storage capacity. Also, it is very essential that the device sustains huge amount of data, without any memory lag and without the device being hanged. Traditionally, when smartphones where launched in the beginning, their storage space usually used to be 4GB or 8GB. As developments took place in the mobile industry, devices with 16GB, 32GB, 64GB, 128GB and more came in to existence. Apple one of the biggest tech giant, usually had memory options starting from 16GB. But recently with their new flagship iPhone 7 model, they have removed the variant of 16GB.

The iPhone 7 is available in 32GB, 128GB and 256GB. Based on such a huge memory and different variants, many a times the user is confused on which option to go for. So here I’ll be providing you on which option you go opt for and why?

With making stunning designs and look of the device, Apple has also mastered in providing high security and durability among their devices. Giving a short and brief about the tech specs of the iPhone 7, as some of you’ll might not be aware of it (not detailed tech specs).

Available in 32, 128 and 256GB variant with 4 vibrant colours and the limited edition colour (RED iPhone). Weighing 138 grams, the device features a 4.7” Retina HD Display. The display is a multi-touch display with IPS technology. Featuring 12MP Rear Camera and 7MP Facetime HD Camera, the device is powered with A10 Fusion chip. That’s all for a basic tech specs about the device. Let us now jump into the comparison of 32GB and 128GB.

As reported by GSMArena, the device which is backed with 32GB storage space is much slower than that of the 128GB in terms of storage performance and memory usage. Agreed by the fact, that the 32GB variant is much more cheaper than the 128GB, but the question here lies is, that is it really worth based on its storage and memory performance?

The applications on the App Store of Apple are first reviewed and then they are put up in the market place. This leads to great quality of the application in the App Store, but the apps are usually of hundreds of megabytes (MB). Of course when you install just one or two apps, you won’t find that relevant. But once you use multiple apps related to work, personal use, business and others, you will realize that the storage takes tons of space in your device.

The device supports 4K (Ultra HD) Video Recording. The video recording is superbly amazing and crisp, but this video builds up and uses a lot of storage space in your device. If you tend to purchase a 32GB iPhone then out of that, approximately, 4GB to 6GB is consumed by the iOS (Operating System) and other built-in-apps (which can’t be uninstalled in order to free your storage). So you get only 28GB of memory space if buying a 32GB model. Out of this 28GB if you tend to install apps, record videos, click live pictures, download movies and other stuff your storage space is stacked completely and in the end you are short of memory.

If you consider the 128GB device model, of course you will be much safer with more memory as Apple does not allow external storage, it is always better to have more memory than required.

This was about memory shortage issue, but based on the storage space, the device also has differences in the way they process the read and write requests. Hilsenteger used the free PerformanceTest Mobile app to compare the read and write speeds of the iPhone. While there was little difference between the read speeds of the 32GB and 128GB models, there’s a huge disparity when it comes to write speed. The 32GB iPhone writes at 42MB per second, which is nearly eight times slower than the 128GB version’s 341MB per second.

Disc speed can make a big difference in real-world performance, especially on the iPhone. iOS is more prone to push apps out of the RAM and store data on the disc drive, so the longer it takes to read and write files, the slow the phone will perform.

More noticeably, tasks like copying movies from a PC to a phone will take much longer on the 32GB model. In addition to that photos shot in the RAW file format, which can be as big as 15MB on the iPhone 7, and you’ll quickly eat through that much storage in a few months. The 128GB option is much better for general use, and you’ll probably forget that there’s an upper limit on your storage at all.

Based on the reports from GSMArena, the details are listed as such:

Storage test Apple iPhone 7 128GB Apple iPhone 7/7 Plus 32GB
Basemark OS II Memory 1721 839
PassMark Disk Mark 69616 43668
PassMark Storage Write 308 Mbyte/s 39.6 Mbyte/s
PassMark Storage Read 926 Mbyte/s 691 Mbyte/s
5min 4K video copy 0:17min 0:52min


Based on the above tests and outputs, it is very clear that the iPhone 7 128GB model is much better than that of the 32GB Model. You spend money, but you save time. And time is money. So I think you should give first priority to the 128GB over the 32GB variant.

So, if you can afford the 128GB iPhone 7, pull the trigger. It will save you from numerous headaches and it could ultimately save you some money. Additional iCloud storage space doesn’t come free. And if you don’t get enough storage, prepare to spend money every month on the service.
