Apple finally bumped up the storage capacity of the base iPhone model to 32GB. So the difference between the 32GB, 64GB and 256GB iPhone 7 is just the amount of sh*t you can store on it. Right?
Well, it turns out that the 32GB iPhone 7 and 7 Plus models have slower storage performance than 128GB and 256GB models.
The video below tests a 32GB iPhone 7 and a 128GB iPhone 7 using a free app, PerformanceTest Mobile. While both devices have similar read speeds, there’s a huge discrepency when it comes to write speeds.
In theory, larger capacity SSDs perform better because manufacturers have to place more NAND chips, in parallel to each other. This means that the SSD controller has an easier time accessing more of the memory than a controller in a smaller capacity SSD.
While this is true, should a 32GB iPhone 7 be almost 10x slower in write speeds than a higher capacity iPhone 7? Just watch the video and draw your own conclusions…
