A slowdown is to be expected with Solid State Disks; as smaller SSDs are slower then larger ones. Simply because larger ones have more NAND chips and are therefore able to write to more locations at once. https://superuser.com/questions/977080/does-a-large-ssd-perf...

#12title omission: "... in benchmarks". In the real world, the flash speed difference is rather insignificant. I don't copy around huge 4K movies on my phone very often.
On some level it doesn't really matter, it stinks but it doesn't matter.
That said it might affect the camera performance in the long run, but then again if you are going to film 4K and take tons of RAW photos get the bigger storage since it's not expandable.

that explains the 25-30% slower read speed, it does not explain the nearly 10 times slower write speed, there must be something else going on

You bring up a good point a 10x slowdown is quite dramatic. I have edited my original post to make it sound like less NAND chips in the SDD isn't the only issue.

And on smartphones, it is very, very seldom the case that flash storage varies in speed between capacities, beyond simply vendor differences. Which is probably the case here.

#18My suspicion is that it has to do with the test and the SLC cache. In the iPhone 7, most of the flash is TLC, but a portion of the flash is configured as much faster (for writes) SLC. The cache buffers a certain amount of writes, later transferring them to TLC. On a bigger drive this cache is bigger. So if the test fits into SLC cache on the bigger phone but falls out of it on the smaller phone, that (combined with l…

#20For those of us the own the Verizon/Sprint version, I wish that Apple would at least match the capabilities of the Samsung S7 that shipped 6 months before the iPhone 7. The difference is the quality of the voice and the ability to communicate when signals are weaker.
