I am a student who owns the iPad Pro 10.5 64GB gold and I have been very happy with it so far. One day I downloaded an app to test my iPad disk speed and noticed the write speed is half the one on my iPhone 8 plus 64GB. I saw a similar thread for iPhone 8/plus/X somewhere on this website and decided do it for the iPad. This is the app I used:
PerformanceTest Mobile

Please Kindly reply with your read/write speed as I will update the average speed on this thread regularly.

I'm familiar with NVMe performance. Thing is even those M.2 2280 usually have at least 2 NAND chips to help with parallelism. If minimum storage wasn't 64GB, I'd agree with you on 500MB/s writes. Alas, there's usually significant performance penalty due to lack of parallelism on very low capacities.

Iirc, starting with the A9 the storage controller is built into the Apple chipset so I highly doubt the 1TB models would have a different storage controller. As you have surmised, what's more likely is the 1TB models having more NAND flash chip packages compared to lower capacities (likely 2 instead of 1).

Mind, since majority of the magic happens in the Apple A12X SoC, rather than the logic board, what we need is more of this:

This link was great to read.

Oh I wanna join in on this. What app are you guys running these test on?

My write speeds are in the 1,400 range which doesn’t sound right. Seems backwards to me. I’ve tried the test numerous times, I cannot get it to complete the disk benchmark and show both read and write speeds. Only write speeds show up, which are oddly high and look more like read speeds to me.




It says I’ve scored 238,920 overall and looking on there website, this is there disk benchmark chart showing recently uploaded benchmark scores of 1TB iPads at the top with the highest at 195,000 range. But, there’s no way to see a break down of what there read/write MB speeds are. So, I have no idea what my write or read speeds actually are..

So I’m really confused by this. I wish I had all of the information here.

Wow!

I get an error when I try to submit the results, and tapping the Storage items in the list causes the speeds to vary quite a bit, but never lower than about 750MByte/Sec.

My 1TB is in line with this. I cannot get the write test to work. But the read MB speed is around 1,300-1,400 MB. I wish the write test would work, but it fails and displays no results. I’ve tried uninstalling no luck.

My overall storage results score is around 240,000.

The 1TB iPads seem to be drastically faster than the lower storage models. I’m guessing they have parallelism.

Or bigger RAM or SLC caching. The PerfTest storage benchmark is just way too short for an accurate gauge of disk performance.

There still fast though. On par with smaller mainstream M.2 ssd’s

Or

raid 0 Sata SSD’s 850 Pro’s or equivalent.

The test is so small that large cache might not help most likely.

It would be great to get some developers to work on some new apps for benchmarking with iOS. Possibly something to test for throttling, and more in depth benchmarks.

I’m surprised it doesn’t exist.

I expect majority of iOS users don't care for benchmarks. Reckon benchmark addicts are probably mostly on Android or Windows. For those that are interested, Geekbench is likely good enough for the majority that do.

I know the storage on new iPads is fast (I think starting with A9 is when they moved to PCI Express). I think PerfTest numbers seem pretty off though. I'm curious what the memory and storage utilization are on yours and @greenteapanda 's iPads are (both 1TB). Given how short the PerfTest is, I wouldn't be surprised if that's affecting the storage scores.

For storage, there's this:
https://itunes.apple.com/app/jazz-disk-bench/id1298441490?mt=8

The Jazz Disk Bench test below uses TestSize(Seq): 1GB and TestCount(Random): 16384. As can be seen from PerfTest screenshot, iPad is a 512GB model (2017 Pro 12.9) and is 90% full. I also didn't bother closing background apps before running the benchmarks.

Nice. The sequential results really show the benefits or parallelism. However, it's the Random(4K) scores that are particularly impressive. Those are proper SSD results (mayhaps not high-end NVMe but certainly at least 2nd or 3rd gen mainstream SATA).

Random 4K tends to not vary much with capacity but I do wonder what the results are like for the A12X/4GB 2018 Pros and the A12/3GB Mini 5 and Air 3 256GB.

For comparison, here are the results from a 128GB iPhone XR (also A12/3GB).

I’m thinking performance is inline with like a Samsung 850 evo drive with the 4K random read and write speeds. Although the sequential read and writes are much faster than a traditional sata SSD.

Hopefully someone will chime in, and run this test on a 64GB iPad Pro or 256GB or 512GB model.

Is the latency so low because it is directly controlled by the CPU? It seems suspiciously lower than even high end SSD’s.

So if I did the tests correctly:

iPad 6th gen (2018 model) 128 GB:

Write/Read
276/913

 

[MichaelPichael]

iPad Air 10.5 (2019 model) 256GB:

Write/Read
618/1615

 

[Aditya rathee]

Very interesting yet not surprising result. I noticed that comparing your result to iPhone 8/plus/X your write speed is about 100-200MB/s lower and my iPad is 100MB/s lower than the same capacity iPhone. it is pretty disappointing knowing Apple didn't use the same SSD on the iPads which was released the same year.
Yeah thanks it was transposed. I have reversed them now.

Can yu tell me how exactly do yu use yr ssd with lightning port
I mean do yu plug in just using lightning to usb c cable or use that apple lightning to usb 3 adapter??

a bit slow at write..

Should i be worried about it🥺?

 

[Digitalguy]

this benchmark doesn't seem very reliable to me. I get higher results on my 128 12.9 first gen than on my 10.5 pro 256GB...

JazzDiskBench with sequential test size set to 1GB is the most reliable storage benchmark I've found on iOS.

not free but I may give it a shot...

 

[aevan]

But my point is that the iPad Pro has slower writing speed than the latest iPhone which I think should be using the same SSDs but apparently they don’t. If you spend so much money on an iPad wouldn’t you want it to have higher writing speed? My iPad only has 70MB/s compared to 190MB/s on my iPhone 8 Plus.

edit: wrong post.

 

[aevan]

If you're willing to shell out $0.99, maybe you can try this:
Jazz Disk Bench by Guangyu Chang
https://itunes.apple.com/us/app/jazz-disk-bench/id1298441490?mt=8

I find 1400MB/s write to be unsustainable considering the iPad likely doesn't have the degree of parallelization as one might get from a larger SSD with multiple NAND flash chips. Burst thanks to either memory or SLC caching, sure, but not sustained. Mind, I'd be quite happy to be proven wrong on this regard.

Note, I believe the storage controller is built into the A12X chipset and addresses raw NAND flash chips.

edit: wrong post.

Tomorrow or soon I’ll post results in regards to my 64GB iPad Pro 10.5…
And funny thing about it… if the rumors are true and the 14 lineup ( more the Pros) get USB 3.0 lightning female port then we can finally get true USB 3.0 via 3.0 lightning cables supplied to the 14 lineup, it’s way overdue for A10X iPad Pro and A9X 12.9 inch one to not be supplied with a USB 3.0 lightning cable.
