Thankfully, it's the read speed that's most important. It determines how fast the phone boots up, or how quickly an app is launched. This is why the 32GB iPhone 7 will boot just as fast as the 256GB one. Bottom line, most of your daily activities on the phone, including watching movies and playing games revolve around reading information off of the phone's SSD. Let's be clear though. Your phone does write data to its SSD, like when you take photos or record a video, it writes that data straight to your local storage. However, these tasks require much less bandwidth than the SSD is actually capable of performing.
SSDs can write data in excess of 100 megabytes per second, Recording a 4K video, the most demanding write job you can do on a phone, only requires a write bandwidth speed of 30MBps, which comes nowhere near your phone's write speed limits, So a faster write speed would make zero difference in this case, It's octane case for apple iphone 6 and 6s - frost/turquoise the same for another heavy write job: transferring data from your computer to your phone, When the phone is physically connected to your computer (say, via a Lightning cable), the speed in which you transfer data from one device to another is determined mostly by the speed of the connection standard, In the case of the iPhone 7, that standard is USB 2.0, which supports data transfer speeds of up to 60MBps at most; however, real-world speeds tend to cap at around 40MBps, Bottom line, USB 2.0 (and 3.0 for that matter, which the iPhone 7 doesn't support) has a slower transfer speed than your actual phone's SSD, making the transfer cable the bottleneck, not your phone..
So if you want to compare the true write speed of the 32GB version and 256GB version of the phone, make sure both have the same amount of free storage space first. Thing is, when you buy a 32GB phone, you're not getting it because you plan to put a bunch of HD movies on it. If you were, then now's the time to start thinking about going with 128GB at a minimum. It'll hold all of your photos/videos, and you usually won't have to worry about erasing anything. So yes, typically there is a speed difference in copying large files to the 32GB versus larger capacities, but how many of us do that on a regular basis? In 2016, that's just not how most people use their phones. As long your phone can stream movies without much trouble, you're probably going to be satisfied with its performance.
The low-capacity version of the phone might have a bit slower storage speed, but in real-world usage, you might not have a different experience at all, So you decided to save money and get the 32GB version of the iPhone 7 (instead of 128GB or octane case for apple iphone 6 and 6s - frost/turquoise that 256GB monster) and now you're wondering if you're on the short end of the performance stick, Well, technically, you are, Lower-capacity storage chips tend to perform slightly slower than higher-capacity ones, It has to do with the number of parallel channels you can put inside solid-state storage devices (SSD) -- the type used in all mobile devices, including Apple's iPhone devices, Higher capacities can have more channels, and more channels equals higher speed, What this means for you is your iPhone might be slower than the 128GB or 256GB models, Or will it?..
You're addicted. If you're seriously thinking about buying a Pokemon Go Plus, there are few other explanations. It's a $35, £35 or AU$50 wearable pin that quietly alerts you to nearby Pokemon -- that way, you don't need to pull out your phone to play the uber-popular Pokemon Go game. Like with the slot machine at a Vegas casino, all you're doing is repeatedly pushing that single button to capture Pokemon, collect items and advance in the game. Push, push, push. Thing is, if you're a Pokemon Go addict, you like it that way.
