- When people think USB,
they usually think of this kind of cable,
which was released in 1996
with numbers like USB 2.0, 3.0, and 4.0 are flying around
and letters like A, B and C
Let's start with a brief summary of what USB is,
letters versus numbers.
Letters have to do with the shape of the connector.
So we've got USB-A which David just showed you.
We've got USB-B, think printers,
and then we've gotten USB-C, which is the smaller one.
And then this is the one that makes people angry
because they have to buy dongles
to work with the older USB-A devices.
Which cable is 80 times faster?
- I don't know. - This one or this one?
- I would guess the bigger one is 80 times better.
- That's right it's 80 times faster,
but I didn't know that when I bought
the other one on amazon.com.
I went on Amazon and I said,
okay, I need a USB-C cable
because I want to transfer videos directly
from the camera to the computer.
I bought two of these Amazon cables,
plugged them in and everything was dirt slow
because even though it's a USB-C cable, it's USB 2.0,
so let's talk about what the numbers mean.
Numbers have to do with speed.
USB. 1.0 came out in 1996, 12 Mbps.
And one of the things that can get confusing here
is that when we talk about speeds, we're talking about bits,
megabits, gigabits.
And when we're talking about files
we're talking about bytes.
So megabytes, gigabytes.
So we're gonna do the math in just a minute.
To make it easier we're gonna deal with bytes
'cause that's kind of the real world file size
transfer speed stuff.
USB 2.0 came out in 2000, 480 Mbps,
and USB 4.0 also known as Thunderbolt 3 and Thunderbolt 4
came out in 2019 and is 40 Gbps.
- Fast.
- Is USB 4.0 better than USB 1.0?
- Yes, 'cause it's a much faster.
- Much faster. - Much faster
- First confusing point,
USB-C, especially USB-C,
just because they look exactly the same
doesn't mean that they're anywhere close
in terms of data transfer speeds.
This one 480 Mbps max, this one 40 Gbps
or 40,000 Mbps fast.
You can buy them both on Amazon and they're both USB-C.
USB 1.0, 12 Mbps.
You take that 12 number and you divide it by eight.
And so it's 1.5 megabytes per second.
You take the bit number, you divide it by eight
and then you get the bytes.
Cause there's eight bits in a byte.
USB 2.0 is actually 60 megabytes per second,
USB 4.0/Thunderbolt 3, Thunderbolt 4,
5 gigabytes per second.
We already talked about how I felt ripped off
a few months ago when I didn't realize I was buying
a USB 2.0 cable and not a USB 3.0 which is what I wanted,
but I have a real gripe here with Apple
and it has to do with the iPhone 13 Pro.
Let's take that out.
It was released this year, 2021.
My Mac was released this year USB 4.0, 40 Gbps.
iPad Pros released in 2021 USB 4.0, 40 Gbps transfer speed.
iPhone 13 Pro released in 2021, USB 4.0?
Nope. - USB 2.0.
Same for the iPhone 13 Pro Max.
And the issue here is apple is talking a lot about
ProRes video on the 13 Pro and 13 Pro max
made that a big selling point
but when you go to transfer those gigantic video files
to your computer, they're very slow.
- Right. It can take forever.
- So in the iPhone settings app,
it says under Apple ProRes, Show Camera Controls,
the ProRes Pro is one of the most popular formats
for video professional post-production.
A minute of 10 bit HDR ProRes is approximately 1.7GB
for HD and 6GB for 4K.
That's one minute. - Right, one minute, 6GB.
How fast does the iPhone transfer data from the phone
to the computer USB 2.0 speeds?
60 megabytes per second, pretty simple math,
100 seconds to transfer one minute of video
from an iPhone to a Mac.
- And that's the optimal speed.
- Right - if it's not perfect
and it usually never is, it's gonna be longer than that.
- We're gonna do kind of a real-world test.
Imagine that you're a videographer.
You've just taken a video that is an hour long.
How long is that gonna take?
We're gonna transfer a one minute video
that David just took with his iPhone to his computer.
I'm gonna set my watch.
- All right. - Stop Watch.
- Let me just pull the right cable
off the cable tree here.
Plug that in.
- Stopwatch.
Are you ready to do this, David?
- Click on my file.
I'll click download and start the timer at the same time.
Three, two, one, go.
It was slightly long as a few seconds over one minute
and we have a slightly larger than 6GB file.
So that kind of checks out.
- That does make sense.
This should take a hundred seconds exactly.
Maybe a little bit more, 105 seconds maybe.
- Oh, this is going.
I think one of the reasons why I really don't like this
is that Apple pitches this is like a pro phone.
This is a phone that they show pro videographers using but
- Well, imagine if you take them like a 30 minute video
or an hour long video and it would just,
it would be very difficult.
- Ridiculous. - And we should also say like,
when you go into the camera app with ProRes on,
they'll say how much time is left
that you can actually record.
And for me it's 32 minutes.
So I couldn't even record a feature length film
on my iPhone if I wanted to.
- Well, you know, you should've got the one terabyte.
- I should've got the one, sure.
Yeah, I think I would, if I'm a professional videographer,
I'm probably opting for something different.
- Probably. - Okay.
We're at 150.
- It was supposed to take a minute and 40 seconds,
100 seconds, maybe a few seconds longer than that
if it was totally ideal conditions.
- And boy we're over two minutes, wow.
- Yeah, I think that usually it's about
one third slower than max speed.
- Yeah, two 15-ish. - And we just hit two, 15
and it's still not done.
- Later.
- All right, it's done. - Here we go.
We'll say two, 33-ish.
- How many seconds is that, David?
(upbeat music)
So if one minute takes two minutes and 36 seconds
to transfer, then an hour long movie,
it's gonna take two hours and 36 minutes to transfer.
Most professional filmmakers do not wanna have
to wait that long.
- The frustrating thing is that Apple could,
if they wanted to build an USB 3.0 to life
on lightening port, but they're just not doing it.
- Right and they did it when they built the USB 3.0 SD card,
two lightening adapter for the iPad Pro like one iPad Pro.
So the lightning port can handle USB 3.0
which is 10 times faster than USB 2.0.
We don't expect, you know, for USB 4.0 maybe.
I mean, that'd be nice, but not necessarily.
- Yeah. - Totally necessary.
But USB 2.0 is ridiculous that we're still transferring
at the speed.
It was technology that was invented in the year 2000.
- Y2K. - Video files are huge.
When we do a recording session,
we usually end up recording with three different cameras,
at least an hour per camera.
So three hours that would take seven hours to transfer.
If we were using iPhone 13 Pros to even start
to be able to edit the videos.
That's insane. - It's a lot.
- Yeah.
- Video transfer speeds are slow.
It still takes us an hour to import everything.
But I wouldn't want to have to wait until tomorrow
just to start video editing.
And they didn't mention that in their commercials.
- Of course, and essentially for us to
some of the things are time sensitive.
- Right. I can't do it.
They can't afford to do it. - Of course
they also didn't mention it in the video.
- Yeah, they wouldn't say, oh yeah.
- I also don't think they mentioned that ProRes video
isn't available on the 128GB variants of the
iPhone on 13 Pro and Pro Max.
- Yeah, but I mean, okay, so 128GB phone,
let's assume that,
10 of that is the operating system.
How many minutes are you gonna get out of that?
- Not very many. - About 20.
Yeah, about 20 minutes, six gigabytes a minute, 120GB.
That's not enough time to take a movie
and even David's phone, like he said,
he's got 33 minutes left? - Yeah.
- If Apple had simply used the latest technology,
the same technology that's available in the Mac
and the iPad Pro, video transfer times would be
80 times faster.
And maybe the iPhone 13 Pro would actually be for Pros,
maybe not called the iPhone 13 Slow.
- You know, should a pilot on the iPhone 13 Pro
never read movie.
