I got iPad Air 4,iPad pro m1 on hand to compare with m2 12.9 iPad Pro. All have 256gb as ssd storage. Using jazz disk lite to test n result is showing that m2 256gb version only 1.5gb/s read n write. The result surprised me because I thought this year only 128gb version ipp ssd is downgraded but now mine 256gb is also affected. 0FDF5643-3764-4BB9-B50B-2492DD604345.png45EEFD38-0205-4FCA-B81C-5F6A6FE046D7.jpeg2ECF9176-85C7-4403-97FC-168F60718AEB.jpeg

I'm not sure what you expected, but I think 1.5gb/s is tremendous. That's like a whole movie in SD quality per second.

I don't quite know why you'd need something faster.

Looks like the same issue as the laptops and desktops. Higher speeds come with larger disk sizes due to ssd configurations.

Guess they are moving away from using 128GB NAND flash module and no new ones are being manufactured.
To those folks asking why that matters, gamers certainly can benefit from faster storage access. Quicker loading at the start and during gaming sessions. Outside of that, faster storage means a more responsive iPadOS with background apps or stage manager.

To be fair, the sequential speed matters less than random access Speed, but still important Nonetheless.

Your device is battery-powered. I would not want a faster SSD at a drastically shorter battery life.
 
Im not sure there is problem there, havent looked for M1 256GB speed tests, but, given my M1 probably has only one chip, Im not sure there is anything to complain about in neither my case, nor yours, unless you really have to have 2TB drive speeds on yours, not just want, but need.

I’m surprised at people asking why they need it to be faster. It’s a pro device. People want or need the speed. It’s like guy asking why anyone would need more than a megabyte of ram or whatever a long time ago.

If nothing else, longevity of the device. What a weird thing to ask in my opinion.

Practically speaking, the overall performance difference from the SSD sequential speed will be negligible. Those random 4K speeds are more important.

Well here is a 256 M1 for comparison.

I know what you meant by the 256gb, but the 1.5gb/s stopped me for moment (seemed strangely slow). Just to avoid confusion, please to use capital B when referring to bytes and keep lowercase b for bits. Most important when referring to speeds - disk throughput is usually quoted in bytes/s whilst the connector (particularly when external) is in bits/s. And, whilst I am nitpicking, giga is written as capital G. So 256 GB and 1.5 GB/s.

Just in case you didn't know, those speeds are in MB/s, not mb/s. MB = megabyte, mb = megabit.

So it's not 1.5gb/s, it's 1.5 gigaBYTES per second.
1.5gbps would indeed be slow, but your actual speeds are about 10 times faster than that.
 
I hate gillibits per second. A gillion times too slow. I bet it renders the iPad all but unusable.

That's got nothing to do with anything.

It's a perfectly valid question. The speed is either good enough or it isn't. Just because it's half the speed of the 512GB model, doesn't mean the speed is too slow. Doesn't mean it's fast enough either. But just saying it's half of the higher model isn't useful.

Is the speed slow enough to cause any real world use drawbacks?
