    A couple weeks ago GSMArena reported that its tests showed that 32GB iPhone 7 and 7 Plus models had slower storage performance than 128GB and 256GB models. Today, Unbox Therapy's Lew Hilsenteger posted a video featuring several speed tests that confirm that 32GB iPhone 7 models have slower data write speeds than other configurations.


    In the video, the free PerformanceTest Mobile [Direct Link] app is used to test the devices, a 32GB iPhone 7 and a 128GB iPhone 7. Both devices have similar read speeds, with the 32GB model reading at 656MB per second and the 128GB model reading at 856MB per second. However, there's a larger discrepancy in the model's write speeds. While the 128GB model writes at 341MB per second, the 32GB model writes at 42MB per second, nearly 8 times slower than the higher capacity model.

    Hilsenteger then performed a real-world test more representative of what a user might encounter, using a MacBook and USB cable to transfer movies over to the two iPhone models. The 256GB model wrote the 4.2GB movie in 2 minutes and 34 seconds while the 32GB model wrote the same file in 3 minutes and 40 seconds.

    Larger capacity SSDs often perform better than smaller capacity SSDs because its controller has access to more NAND flash memory chips, according to How-To Geek. Manufacturers have to place more NAND chips in higher capacity SSDs, and when they do they place them 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, which wouldn't have the NAND chips in parallel to each other.

    This is very very normal for how solid storage works.

    That won't stop the upcoming class-action suit...in 3...2...1...

    To make the Unbox Therapy guy seem less annoying, imagine he got tanked before shooting the video and is trying his damnedest to seem sober.

    It… it doesn't work, but it's a fun mental exercise.

    Come on guys. Why feature this muppet's video? He's like the Buzzfeed of the YouTube tech community.

    How does this compare to speeds for the iPhone 6s/6? 128GB vs 16GB?

    Now the iMac sales decline, Apple must put the pile of 5400 RPM HDD stock somewhere.

    8 times slower is NOT normal.

    Shouldn't the article read "more than 8 times"? I've never multiplied MB but 8x42 is 336 and 341>336.

    Sounds normal. Lower capacity SSDs have been like this for ages.

    Not this guy again... he lives off these kind of stuff.

    You could say the 128/256 GB models are faster, and, as anyone can see in the next video, even the 32GB model blows the competition out of the water in terms of storage speed. How many people transfer 4GB movies regularly using iTunes? If we do some everyday stuff like opening/switching apps, taking photos and videos, streaming content, is there a tangible difference between the models?

    In the upside, people with that little storage won't routinely be transferring such huge files onto and off their phones, so I guess it kinda cancels out.

    Apple has never made any claims to the speed of the memory within the device. Good luck with that class action. :p

    Exactly, it's nothing new. If you want faster, go higher. Apple would probably prefer it.:D

    Lmao at people immediately dismissing this guy for attacking Apple. And no, 8 times slower is NOT NORMAL. "How many people transfer 4GB movies regularly using iTunes?"

    Excuses, pathetic from Apple.

    No! We just got the base model bumped-up to 32GB, and now we have to hear the negative side! ;)
