Has anybody tried the iPad Pro 2021 and Samsung T7 SSD? What read/write speed did you get?

Ok, it seemed extremely precise for that, anyway I think the same speed should apply to A12X/Z...(which is 10Gb/s) Based on many reviews, TB3 speeds are still not enabled on iPadOS 14

Not necessarily. Unless you get perfectly divisible numbers, you're bound to get fractions/decimals.

With that said, the T7 itself is limited to 1GB/s so not a particularly good test for TB3.

It is a affordable small USB 3.2 gen 2 SSD. Question is how it is performing on the iPad Pro 2021.

Ok, I tried myself:
Transferring a 5GB file to the iPad: 16 seconds
Transferring a 5GB file to the SSD: 2 minutes and 19 seconds.
?

Ordered a USB 4.0 cable now

Yes, APFS formatted it can reach up to 400 MB/s without data loss.
I formatted the T7 to APFS this afternoon,

copying 10gb of video files from T7 to iPad.
ExFat = 20secs
APFS = 15secs

copying 10gb of video files from iPad to T7
ExFat = 1min 50secs
APFS = 27secs

I now don’t need ExFat as i have no need to plug into to a Windows PC so all is fairly good for me, i expect the speed results will be even quicker doing the same test on my iMac Mini M1 ?

maybe there will be more to come wit IPadOS 15?

Clover Hater should have added “ I DONT REPLY TO QUESTIONS I COMMENTED ON” ?

I’m sorry to bring this back up but you guys’ speeds are insane
I’m transferring five videos - 2 @ 4K (9.5-10GB) 2 @ 1080 (3.5GB) and 1 @ iPhone standard size @ about 1.5-2GB. Total of 25GB from the M1 12.9” iPad Pro 2TB to a 2TB Samsung T-7.
It took 16 minutes!!!
That seems insane looking at your digits but it’s formatted ExFat - no clue the difference would be that significant.

I’m going to have to reformat and move everything off in mirror to a different drive to wipe it.

That’s brutal because it holds a 1TB+ music and video library folder - the main iTunes or Music folder

That’s the only way to reformat, right? I can’t just reformat with the data already on the drive right?

Ugh

Reformat = data gone.

Reformatting won't make any difference

It simply does not handle exFAT well in terms of performance or dependability.
Yeah I guess we can say it's part of the exFAT anomaly with iPadOS... Which is a shame since this is supposed to be multi-platform file system (iOS, MacOS, Windows, Android). For those locked in the Apple eco-system this might not matter, but for everyone else it's an annoyance...
