iPad iPad Air 2 use very slow TLC nand

[Doomtomb]

dude you need to calm down. The iPad Air 2 is snappier than any previous iOS device Apple has released thanks to the A8X processor. Everything you do is super fast. Transferring files onto your iPad? Does anybody still do that? Streaming bro

Look you must at least acknowledge their reasons for going with TLC, it stores more bits per area. It's the only way to economically give you the amount of storage you are asking for in such a thin device without taking space from things like... the battery. Some seconds slower doesn't mean it's, I quote "***** NAND"

Just for fun, since I got sucked into this thread, I checked my 64 G cellular one, and I got TLC like most people on the thread. I used the Phone Doctor Plus app designed for iPhone.

On the other hand my 64 G iPhone 6 is MLC.

So far no reboot/other issues for either device.

You are talking about the Air 2 is TLC right?

How did you check using this app as I can't find it using this? I used the other app mentioned on here to discover my 64gb air 2 wifi uses MLC

Im not sure if they can change the tlc nand cause it uses 33% less room. Maybe that how they achieved to make the ipad that thinn. Its crazy

Yet another reason why going this thin is stupid.

Im sorry your life is ruined just return the tablet and get something else...Im not sure what you want to hear...Apple is not going to change business practices cause FROM0TOHERO is having a heart attack with a TLC chip...its just hilarious someone would lose sleep over this. Hope you find a device with perfect specs for you.

The OP is hilarious, Happy with iPad, reads something about something he never heard of before. Joins MacR, has 100 posts all on this memory unicorn. 18 seconds gone from his life. Thanks for the great laugh. Oh and please smash your POS iPad Air 2 on the closest hard surface.

Its funny, how you know that i never heard of TLC vs MLC before? The first time i hade to choose between the two was when i went to buy a SSD for my laptop. The TLC drives where way cheaper. But there where also some complaints about the TLC ssd's so i went with the MLC drive from Samsung. And btw its not a huge issue i was just a little disappointed that the Air 1 was a little faster. Like i sayed before, i stoped worrying and just hope my Air 2 keeps going and is ok. My first Air 2 hade a strange issue. From time to time there was a clicking sound that seemed to come out of the speakers. I made a appointment and got it replaced. Till now the new unit works ok. And please folks, im finished with the TLC vs MLC issue. I just hope my unit works and is ok.

The air 1 may transfer very large 1gb files a few seconds faster but in everything else the air 1 is far slower than the air 2. Let's just clarify that and end the thread.

Well yeah the Air 2 is faster thats right. But in everyday usage the diffrence is not that huge.

Games is where the air 2 was probably meant to really excel in. What other purpose would need twice the cpu/gpu performance over the air 1?

Wakes up. Reads this thread as he eats breakfast. Gets to thinking. Do the Crunch Berries that he is eating, taste the same as an original box of Crunch Berries? Or did they change the ingredients? He decides to investigate further, and finds startling evidence that they are in fact not the same! Amazing, the newer one has less sugar! They do taste different! He now goes into depression thinking how this discovery has ruined 20 seconds of life.

Sitting an wondering how he can move on, now that he know's the hidden truth to this fact, he runs to the one true constant that he can trust. The one last constant that even TLC nand can't destroy...................................

He grabs the box of Cheerios.

The main area of performance improvement is 2 gb ram. I have both iPad Air 1 and 2 side by side and Air 2 shines with it's 2 gb ram in day to day use.

While my iPad Air 2 has TLC compared to MLC in Air 1, I saw no noticeable difference between the two while syncing same data.

If i pay premium prices, i want that best possible parts in my electric devices. My PC have a 1300 Dollar Graphic Card. If i want medium parts i will buy a cheap HP tablet or something alike. But if a pay almost 900 Dollars for a tablet, i dont want the cheapest nand available. Pathetic or not, i guess you dont get the point. If you buy a car u take the cheapest tires available or you get a quality product? Think about it. And btw i have 2 children and sometimes more problems than i need, but i care what parts my devices or cars have!

Until you can build your own tablet I doubt you're going to be happy. I don't understand any person in the world buying a product, using it, complaining about it's internal components for one and then on top of it all continuing to use the product.
I would never understand the point of purchasing ANYTHING and keeping a product I don't feel are up to my standards. I would return and get my money back and wait until such an acceptable product hits the market that I feel is worthy of spending the money on, one that is premium enough for premium pricing whatever that is supposed to mean.
For the tires question, I buy the most expensive tire on the market for my car which is also the most quiet and best riding tire but also wears out the quickest, in less than 1 yr per set or do I drop my standards and buy a cheaper tire that lasts 3x as long but has more road noise and a harder ride thus? neither answer makes sense, I just pick the one I'm willing to live with because I can not have both.


After this post I'm going to meet a few couples this evening for drinks and a nice dinner at Del Frisco's to debate how TLC NAND in my iPad Air 2 is destroying the quality of my life. As well as tire pricing/softness/noise/braking/seasonal use.

Which area does it shine in with 2GB? I'd like to test a side by side scenario as well.

Multitasking has improved so much on Air 2. Also, Safari tab reload problem has been 80% reduced. Further optimisations are still needed for iPad Safari to eliminate tab reloading problem completely.

Regarding TLC vs MLC debate, even Samsung EVO 840 SSD uses TLC NAND and still the performance is stunning. So instead of we debating on performance, the custom controller and optimisations done by Apple must negate the performance hit.

Apple is definitely doing cost cutting as this years Air 2's are 60-70 $ cheaper than last year's.

 

[thadoggfather]

I wonder if 2015 build iPads are still shipping with Tlc. I would suspect so

 

[Alphazoid]

Mine is using MLC. It's a 16GB model though.

My 64GB 6 Plus also uses MLC.

On Samsung TLC NAND

For those who are interested in the developments in Samsung TLC performance degradation over time, there is now a new (as of 20th Feb) fix for the famous Samsung 840 EVO and NON-EVO drives. As you may know, the 840 series including the newer EVO are Samsung's bread and butter SSD series. The controller and firmware technologies are most likely shared with TLC eMMC modules used in tablets including possibly the Air 2.

Apparently no one knows the root cause other than Samsung (who have not shared the details as of yet with Anandtech) and whether or not this affects the iPad I do not know. However, this should be at least interesting as it is tied to the discussion at hand and those who use TLC NAND-based SSDs for their other machines.

It went something like below.

Performance degradation over time observed on Samsung 840 & 840 EVO drives that was covered on Anandtech in Sept. of 2014:
http://www.anandtech.com/show/8550/...40-evo-read-performance-bug-fix-is-on-the-way

Then a while later progressed to a fix being issued by Samsung as a firmware update in Oct of 2014:
http://www.anandtech.com/show/8617/...e-to-fix-the-ssd-840-evo-read-performance-bug

Samsung then followed up just now in late Feb of 2015 with yet another attempt at the fix not yet available, since the earlier fix proved no better in the long run:
http://www.anandtech.com/show/8997/...0-evo-performance-another-fix-is-in-the-works

I guess there may be a link between the Samsung TLC and the iPad Air 2, since other TLCs are following Samsung's lead and may have forced Apple to switch to MLC NAND due to long-term performance degradation concerns that still is being fixed currently.

This is just my guess at drawing the links.

Sorry to dig up an old thread, but I wanted to share my info. I got my iPad Air 2 128GB LTE two weeks ago. I used Phone Doctor to test the storage and got these results. To my knowledge this is pretty good, yes?

I got my 64gb iPad Air 2 LTE on release day and it has about the same results.
