  • So, at first glance,

  • these two iPhone's in front of me,

  • they look to be exactly the same, right?

  • I mean, iPhone 7's,

  • matte black finish.

  • For the most part they are -

  • or are they?

  • Hmmmmmmm?

  • Ok, fine, they are a little bit different.

  • this one over here is 256GB model.

  • These one over here is a 32GB model.

  • Now:

  • when you walk into the store

  • and you decide which version

  • you're going to purchase,

  • you think:

  • the 32GB model is cheaper

  • I just wanna get in at the cheapest price point

  • cuz 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 32GB model

  • might be substantialy 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 chintzier

  • 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

  • So open your eyes.

  • So this one on the left over here,

  • capacity: 248.8 gigabytes of course

  • that's the formatted size that makes

  • this one to 256 gigabyte model.

  • 27.85 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 write 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 write.

  • You can already see how

  • much slower that was just by watching

  • the bar move along

  • that's 42.4 megabytes per second

  • the read is not such a big deal, right?

  • The less expensive ssds almost always

  • get hit in the write performance this

  • read speed is in the same neighborhood

  • as the 256 gigabyte model, but the write

  • speed holy smokes you're talking about

  • almost 10 times faster write 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 benchmark, 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 we're

  • going to time it. Nothing else is syncing

  • 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 gonna use another

  • device just for the purpose of having

  • a clock running.

  • 3...

  • 2...

  • 1...

  • Okay, 2 minutes 34 seconds around

  • two-and-a-half minutes for 4.2 gigabyte file.

  • Let's eject this device and replace

  • it with a 32 gigabyte model.

  • Select Star Wars New Hope, 4.2 gigabytes in...

  • 3...

  • 2...

  • 1...

  • Now keep an eye on this one guys

  • there we go 3 minutes and 40 seconds!

  • The evidence is there. So the bar finish

  • and I bet if you walked into an apple

  • store and you ask the employee what was

  • the difference between 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 media head, you're constantly

  • transferring large, files pictures, videos

  • there's all types of scenarios where

  • 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 in the apple

  • store, so that's why I'm doing it for you.

So, at first glance,
