iPhone 7 storage speeds across different sizes?

This video seems to suggest the 32 GB version is significantly slower than the 256 GB version of the iPhone 7 - specially on the write speeds. To the tune of 8 times slower!

Anyone with access to a 32 GB and a 128 or 256 GB version that can test to verify?
 
Firstly, I doubt the slower speeds ever matters in the real-world, and secondly I'm pretty sure intelligent people don't buy iPhone 6 or later with the lowest tier storage.

8 times slower write speeds is quite significant, don't you think?

Write speeds of 42 MB/s vs 360 MB/s without disclosing it to the consumer is very shady.

However, I think the reason why you have this discrepancy in speeds is quite straight forward.
256 GB is 8 times larger than 32 GB, so I could theorize that the write performance is based on how many blocks of 32 GB you have. This can be confirmed with a 128 GB iPhone 7. If it writes 4 times faster than then 32 GB version, it's clear.

I agree with Palladium. Even with your example, I fail to see how this will affect users of the device at all. The only heavy write performance necessary for the device is shooting 4K video... which no matter which device you're using works just fine. So with that out of the way, what else is going to need quick write performance? (Photos, even in burst would be less... soooo).

Terrible read performance would matter more, as in theory that would slow apps from loading and etc.
 
I don't think its shady since they never told you that you would get X performance out of the nand. If they did then you would have a point. They tell you that you get 32gb and that's what you get. This is fairly standard for Apple, they aren't in the business of selling specs (you'll notice they don't say how much ram their iOS devices have either), they sell you the experience which they do for the most part deliver on.
 
This is standard practice in all flash-based devices. If you buy a lower capacity, you get a slower speed, the # of blocks of NAND you have dictate the speeds you observe, so naturally, less NAND is less speed. Apple never promised anything with regards to speed on any of the devices or across the platform, so who cares? Oh, YouTubers.
 
Seems to be a common theme among SSD type storage which is what the iPhone uses. Larger the size, better the speed. 8x does sound a little high though.
