How you can judge that? Im not against TLC. IM JUST AGAINST BUYING A PRODUCT THAT IS IN N TRANSFERING FILES SLOWER THAN MY AIR 1

iPad iPad Air 2 use very slow TLC nand

So you say it dosent matter if you have TLC OR MLC? If you could choose your phone with MLC would you take the TLC? I doubt that
The point is I don't care.
And if it wasn't for forums like this, you wouldn't care too....
I actually never asked what kind of NAND my iDevices were using.... I have a TLC ssd on my MacBook pro, where performances are very different.

Your mac book pro have TLC ? It came like this from the factory?

No they don't. They changed from Toshiba to Samsung.
Everything else is just speculation, since Samsung is a big TLC manufacturer (and their TLC NAND are quite fast and reliable).

My MacBook has a Samsung 840 ssd unit. A drive very reliable and with balanced performances.
So it would be ok for you if our ipads have TLC and the ones they buy in some weeks have MLC? And did you not upgrade to have a faster device? Whats the point to buy the air 2 if the Air 1 is basically faster in transferring big files? I use alot of big video files, and really there is a big difference while transferring them.
I dont understand why they choose a slower nand and are trying to convince us it is faster. Maybe in alot of small tasks its faster. But if you download a movie direct on the air 2 and open it in a other player, it takes forever till the movie is transferred. While constantly the air 1 outperforms the air 2 by minimum of 30-40 Seconds. In computer world 30 seconds are a very long time
There are operations where TLC NAND could be faster than MLC, so your assumption that your iPad is always slower is just baseless.
I never sayed its always slower

But while transfering files bigger than 1GB the Air 1 outperformed the Air 2 always by 15-30 Seconds

You are concerning about nothing.
The only concern could be about a defective NAND controller, that was the initial issue on some 128 Gb models.
But if your unit isn't affected, as I hope, than it's not a big deal.
I'd suggest you to take a look at Anandtech websites and do a little search about TLC. You'll discover that there are very good SSD using those NAND.
And the only time TLC is faster, is in writing small data blocks. It doesn't preform that well on bigger files. Plus it have shorter lifespan. But that is only if you wright more than 10-20GB a day
----------
And be honest, you would not be a little disappointed if your old ipad was faster than the new one?

Unfortunately I can't make a direct comparison like you did, so I don't know if your air 2 is defective or not.
But how many times do you need to transfer such a big file on your iPad ? In my case almost never.
If you do that daily then I can understand your complain.
iPad Air 2 use very slow TLC nand
Thats my main issue. I transfer many and big video files. As example, i took a 1700MB FILE the AIR 1 hade 47seconds, while the Air 2 used 59 seconds
----------
Now everywhere before i got the air 2 i checked the nand speeds in the reviews. Each review gave a very good benchmark result for the nand. Why? Because most benchmarks use small block writings, therefore the good results. But that's a little misleading

That's not true. There are many read situations where TLC are faster. And read is actually a big party of a tablet usage....
Shorter lifespan? Your iPad will probably last ten years, as far as NAND are concerned. Are you going to use it for ten years ?
I can't argue about your usage, but actually small blocks reads and writes are the typical normal usage.
If those 12" are a problem to you, then you'd better return your iPad. For most customers it isn't an issue.
----------
Guess i wont even use it more than a year

Ok ok i understand im crazy
No you're not crazy.i can understand some of your concerns.
Here's a post anyone who thinks TLC doesn't have issues can read. Contains links to benchmarks and news articles.

There is a lot of rumor and speculation about this, but I still have yet to see a single definitive piece of proof that TLC NAND is universally "defective." Slower, possibly, but that issue has been beaten to death already: in nearly all the applications where an iPad or tablet computer is used, a user largely won't notice the difference unless they look hard enough. And in the OPs case, he had to measure transfer times before he could see differences of a few seconds for very large files.
Will this affect access for playback? Absolutely not. Even the slowest, most "inferior" NAND flash far exceeds the common playback speeds of video content even to 4K resolution.
Will it have a shorter lifespan? There has been no concrete evidence of this either.
This is no different from buying a 128GB MacBook Air and freaking out because the 500GB model is "faster." In everyday use, the throughput difference isn't noticeable, except in applications where the NAND flash is unduly stressed and the life of the storage will be shortened anyway from that stress.
Most people who obsess over these things are likely shortening the lifespans of their units more through repeated, deliberate write/read testing, than by any perceived "defect" inherent in the hardware.
If you really want to take your iPad back based on faulty information and speculation, that's fine. But you should know the validity of the information you're basing your decision on.
Yes mine Air one also have MLC.
----------
Do you have the Air 1? If yes test it against the Air 2. It is slower. Much slower
