so at first glance these two iPhones in front of me they look to be exactly the same right I mean iPhone sevens matte black finish for the most part they are or are they hmm okay fine they're a little bit different this one over here is a 256 gigabyte model this one over here is a 32 gigabyte model now when you walk into the store and you decide which version you're gonna purchase you think the 32 gigabyte model is cheaper I just want to get in at the cheapest price point because I don't need all that much storage but the story's a little bit deeper than that Apple might not be giving you the whole picture here turns out that the 32 gigabyte model might be substantially slower than the larger capacity models not all storage is created equal not all of it is the same speed and what happened here Apple probably went a little bit chintzy err on the lower capacity models in terms of the quality or caliber of storage hence a speed difference now I'm going to test this out today to open your eyes so this one on the left over here capacity to forty eight point eight gigabytes of course that's the formatted size that makes this one the 256 gigabyte model twenty seven point eight five gigabytes that makes this the formatted size of the 32 gigabyte model you can see there I've got something on here called performance test from your CPU to your memory to your storage which is the thing we're interested in today if I tap on storage right speed you can see 359 megabytes per second the read speed 851 megabytes per second now over on the right here let's go ahead and hit the storage right you can already see how much slower that was just by watching the bar move along that's forty two point four megabytes per second the read is not such a big deal right the less expensive SSDs almost always get hit in the right performance this read speed is in the same neighborhood as the 256 gigabyte model but the right speed all these smokes you're talking about almost 10 times faster right speeds on the larger capacity iPhone 7 let me paint a picture I've got a laptop over here this laptop has some movies on it some movies and iTunes Star Wars being one of them never mind the synthetic let's transfer it over like any normal user would do so let's kick it off the 256 gigabyte I'm going to plug it in I'm going to begin to transfer and we're going to time it nothing else is sinking on this iTunes besides this movie file for comparison it's a 4.2 gigabyte 1080p video file Star Wars a new hope I'm going to use another device just for the purpose of having a clock running three two one okay two minutes 34 seconds around two and a half minutes for a 4.2 gigabyte file let's eject this device and replace it with the 32 gigabyte model select Star Wars and New Hope 4.2 gigabytes in three two one now keep an eye on this one guys there we go three minutes and 40 seconds the evidence is there so the bar finish and I bet if you walked into an Apple store and you asked the employee what was the difference between the 32 gigabyte model and the 256 gigabyte or 128 gigabyte model they would tell you Oh sir ma'am miss it's just the amount of stuff you can store on there not exactly true if you're a media head you're constantly transferring large files pictures videos there's all types of scenarios we're having a slower write speed on your device could affect performance as you've just seen I don't think it's worth the performance hit considering the savings it would be nice though if Apple was a little bit more transparent about that performance difference I don't think you'll find people saying it in the Apple Store so that's why I'm doing it for you
