Has Apple FIXED Thunderbolt on M1 iPad Pro?

In this video I re-visit my Thunderbolt tests on the M1 iPad Pro, but this time with iPadOS 15 Developer Beta 5 installed. Have the speeds improved?

with the new m1 ipad pro and i was
00:04
testing the speed of the thunderbolt
00:05
port apple advertises its devices having
00:08
thunderbolt and being suitable for use
00:10
with fast external storage so we checked
00:13
it out with an external ssd and the
00:16
results were very underwhelming if you
00:18
want to check that video out there’s a
00:20
link up here
00:22
now we’re going to test it again with
00:24
ipad os beta 5. let’s see whether apple
00:27
has fixed these issues
00:32
to test the performance of the
00:33
thunderbolt port we’re going to be
00:34
copying some files what i did last time
00:37
is i created a folder with lots of
00:39
different types of files and sizes of
00:41
files and it came to about 26 gigabytes
00:44
and i then created an image a single
00:46
image file of the same size
00:48
so we thought we would test both of
00:50
those to see whether there was any major
00:52
difference between them
00:53
and let’s just bring up the results from
00:55
that previous test so first of all it’s
00:57
the read test so this is copying from
00:59
the external drive to the internal ssd
01:02
of the ipad pro and we can see that the
01:04
single file took 47 seconds
01:07
that was one minute 20 for the folder of
01:09
mix files now if you just compare those
01:11
figures with say the m1 mac mini you can
01:14
see that the mac mini managed to read
01:16
the single file in 12 seconds and the
01:18
older of mixed files in 13 seconds so
01:22
the thunderbolt performance of the ipad
01:24
pro is really lagging behind
01:26
other machines with the m1 chip like the
01:28
m1 mac mini now if we look at the right
01:31
performance so this is copying from the
01:32
internal ssd on the ipad to the external
01:35
ssd
01:36
it took 3 minutes 44 seconds for that
01:38
single file and 4 minutes and 2 seconds
01:41
for the folder of mixed files now again
01:44
if we compare that with the m1 mac mini
01:46
we can see that it
01:47
did the single file in 23 seconds and
01:50
the folder of mixed files well that was
01:52
also 23 seconds so again the thunderbolt
01:56
port on the m1 ipad pro running ipad os
01:58
14 it just doesn’t work as advertised
02:02
and i took quite a bit of heat in the
02:03
comments over pointing this out a lot of
02:06
people saying that well i shouldn’t be
02:08
saying this because apple are going to
02:09
fix it anyway in ipad os 15.
02:13
this argument just doesn’t stand up you
02:15
can’t use your ipad without ipad os and
02:18
you can’t use ipad os without an ipad
02:21
the two things go together and they are
02:23
one product two halves of one product if
02:25
you like
02:26
so
02:27
for apple they’re currently selling the
02:29
m1 ipad pro with ipad os 14 and they’re
02:32
marketing it as having this thunderbolt
02:34
functionality but it doesn’t work so
02:36
apple deserve to be called out on that
02:38
and they should respond really to all of
02:40
the other reviewers who are saying the
02:42
same thing as me the thunderbolt port is
02:44
not working properly something else that
02:46
was said in the comments as well is that
02:48
the ssd inside the ipad pro is affecting
02:51
things and perhaps slowing things down
02:53
a couple of people even said that it’s
02:54
an emmc drive inside the ipad um it
02:58
isn’t it’s nvme uh all of the ipad pros
03:00
are nvme and they have been for a while
03:03
in fact even the iphones since the 6s
03:06
have nvme drives in them but it’s not as
03:08
fast as the drive that you’ll get in the
03:11
m1 mac mini
03:12
i found an app called jazz bench on the
03:16
ipad and i just i don’t know how
03:17
accurate that is but i ran it
03:19
and it shows about 1900 megabytes per
03:22
second for that internal drive on the m1
03:24
ipad so i don’t think that is the
03:26
bottleneck here at all
03:27
so inside this thunderbolt enclosure
03:30
i’ve got an nvme drive it’s a western
03:32
digital black sn750 i think it’s a 512
03:36
gigabyte model
03:37
this thunderbolt enclosure i’ve tested
03:39
this with a windows pc with thunderbolt
03:42
i’ve tested it with intel max and i’ve
03:44
tested it with the m1 mac mini and it
03:46
runs very quickly on all of those
03:47
machines it is only the m1 ipad pro that
03:50
seems to struggle with writing to this
03:52
drive so let’s see how this thunderbolt
03:54
drive does now with ipad os 15.
03:57
of course the file system on ipad os
03:59
isn’t the greatest there aren’t loads of
04:01
benchmarking tools that we can use to
04:03
test this so we’re going to go back to
04:05
the old trusty stopwatch so erin i’ve
04:07
got a job for you
04:09
erin is going to be my trusty assistant
04:11
here i hope you’ve got your stopwatch
04:12
ready and i’ve got to say erin i i took
04:15
the time today to pop on a shirt i’ve
04:17
even broken out the cufflinks and um
04:20
it’s nice to see you made an effort
04:21
anyway
04:24
so i’m going to start the file copying
04:26
and i’ll tell erin when to go and she’s
04:27
just going to hold up the stopwatch and
04:30
to save your pain we’re going to speed
04:32
up the footage
04:37
now i should say that we’re testing this
04:39
live i haven’t pre-done these tests
04:41
before recording this video so what
04:42
you’re getting is our actual reaction to
04:44
this the time it took here to copy the
04:47
single file from the internal ssd to the
04:49
external ssd was 31 seconds how about
04:53
that so that’s a lot quicker than the
04:55
previous uh three minutes of 44 seconds
04:58
so it does indeed look like apple have
05:00
fixed it
05:01
so now we’re going to try the folder of
05:03
mixed files
05:11
so an almost identical time for the
05:14
folder of mixed files at
05:16
well i think we’ll call that 31 seconds
05:18
again so basically the same and a
05:20
massive improvement on performance from
05:22
the previous four minutes and two
05:24
seconds
05:25
so now what we’re going to do is copy
05:26
those files back to the internal ssd on
05:29
the ipad pro
05:37
there’s a bit of a theme developing here
05:39
because that’s uh 31 seconds again uh
05:42
that’s for the single file reading back
05:44
in and previously it took 47 seconds so
05:47
again we’ve got a performance bump
05:49
so last of all we’ll try that folder of
05:52
mixed files
05:59
yeah you guessed it 31 seconds brilliant
06:02
so everything takes 31 seconds now in
06:04
ipad os 15.
06:06
what a great result
06:08
thank you so much for your help erin i
06:10
quite literally could have done it
06:11
without you
06:15
so we’ll pop up a graph on screen now of
06:17
the comparison between previously on
06:20
ipad os 14 and with ipad os 15 beta 5.
06:24
and we’ll just pop in as well the mac
06:27
mini’s results with these because this
06:29
is what the m1 chip is actually capable
06:31
of
06:32
and you’ll see there’s still a fairly
06:34
big performance difference between the
06:36
m1 mac mini and the ipad pro but
06:39
considering how bad it was before i’m
06:41
pretty chuffed to see these results and
06:43
i’m really glad that apple has sorted
06:45
out this issue i think it would have
06:46
been better if apple didn’t market the
06:48
product as having something that wasn’t
06:50
available and still isn’t technically
06:52
because ipad os 15 hasn’t officially
06:55
been released yet and i’ve heard from
06:57
people in the comments section who
06:58
bought this ipad and were bitterly
06:59
disappointed because they were hoping
07:01
for better thunderbolt performance
07:04
i think apple should have been a bit
07:05
more upfront and just said thunderbolt
07:07
is coming in the next operating system
07:09
would that have stopped you from buying
07:10
an m1 ipad pro
07:12
it wouldn’t have changed my decision and
07:14
i’d have felt a lot better about it
07:16
instead i feel a little bit cheated by
07:18
apple for the uh six months that i’ve
07:20
spent without having the thing that i
07:22
paid for
07:23
uh what do you think i’m sure you’ll let
07:25
me know in the comments section
