According to Samsung itself, a strong proponent of TLC NAND, a TLC is 4 times slower in writing and 2.5 times slower in reading than SLC:

this is so dumb. It doesn't even make sense that apple used different chips in the 64gb iPhone 6 and 128 iPhone 6 +
Apple Said to Be Stopping Use of TLC NAND Flash in iPhone 6 and 6 Plus After ...
No it doesn't. That was my first tipoff that the original story was a fraud. The other tipoff was that I have one of the supposedly flawed phones which hasn't had a single problem in over a month of use.

I have a 6 64GB model, it has 49.6 GB of free space. I get crashes almost everyday. I have been to the Apple Store they tested it then a week later swapped it out because it still happens. Not sure what the cause is but its a little aggravating but I'm not going back for a swap out to get the same issue. I called Apple and let them diagnose it over the computer but more to let them know about the issue and hoping it helps get a fix out there quicker.
I have one other 6 64GB in my house and it has no issues.

Not, it is not, as Apple could use several vendors alternative components for the same 64GB device. In one rumor leakage this was mentioned:
You can see that for 64GB FLASH, Apple could mount 3 different compatible vendors: Hynix, Toshiba or Sandisk, and maybe one of them is giving the issues to the users with reboots problems.
You can see that for the 128GB, Apple only got one vendor at that time (Toshiba). So, if we would like to guess something, I would say that the iPhones6/6+ with Toshiba FLASH memories (64GB nor 128GB) are the ones with issues.
Of course, I think is impossble to know which device is assembled in your iPhone without opening it or without any special developer SW to check it (with I think nobody of us has).
It would be nice to get a benchmark from a crashing device. As you can see in the previous posts, there are 4x write speed differences between different devices.
Somehow I bet problematic devices have the slower flash (probably TLC).
If there is some truth in the Korean rumor, it could be Apple is test-manufacturing only some units with these different flashes.
I am fully agree, we need performance benchmarchs from the community. Although my previous post doesnt mention, maybe the Sandisk 64GB is a TCL but the Hynix or Toshiba are 64GB MCL versions. So, the people with MCL 64GB versions should have faster devices.
Using Performance Test Mobile on my 6+ 128GB -
Storage Write 135 MByte/Sec
Storage Read 195 MByte/Sec
Memory Write 494 MByte/Sec
Memory Rear 631 MByte/Sec
This phone has crashed half a dozen times but not since last week now.
This one is different again, storage write is similar (just slightly lower) but all remain scores (storage read and RAM) are much slower than my iP6!
Interesting discussion. So if I were to buy an iPhone 6, would you recommend getting the 128 GB model over the 64 GB model in regards to these crashes and speed issues?
Difficult to say, very few people posted their result. Up to now my iPhone 6 128GB has the best performance both in read and write speed... and it never crashed.
But as fas as I know nobody else posted results from a similar device.
Read this article a while back and thought nothing of it,
Until it happened to me this morning,
I have an iPhone 6+ 128GB
I was in the App Store updating my apps then all of a sudden a blue screen covered my phone screen and then the apple logo l appeared off & on my screen & then a reboot it.
What should I do?
Wait to see if it happens again? & then take it to apple?

Probably just Safari being the piece of crap that it is. I use iCab for web browsing. Never liked Safari on my Mac either. I use Firefox there.
An issue typically doesn't go away for no reason.
It's just dormant to awake at a later time.
Just a quick summary of the current community results.... really did not expect such variance!
Code:
Device ____ User ____ Write Read
iPhone 6 128GB eclipsevv 174 363
iPhone 6 64GB kemal __ 54 337
iPhone 6+ 128GB TEMPA __ 135 195
iPad Air2 64GB nagypeter 161 932Very interesting! We would need more benchmarks to confirm, but it seems each device gives consistent results:
- iPhone 6 128GB: fast write, fast read
- iPhone 6 64GB: slow write, fast read
- iPhone 6+ 128GB: fast write, slow read
Code:

iPad Air2 64GB nagypeter 161 932Hello,
Excuse me for my poor english, I'm french ;-)
I have the two last devices : iPad Air 2 64gb and iPhone 6 64gb ( iPhone just purchased yesterday)
The results with PerformanceTest Mobile :
iPhone 6 64gb : Storage write 165 MByte/sec; Storage read 336 Mbyte/sec
iPad Air 2 : Storage write 172 MByte/sec; Storage read 975 Mbyte/sec
Iphone free memory : 47,4Go
Ipad free memory : 46 Go

Thank you!
This is unlike the other iPhone 6 64GB timings, which had a much slower write rate.
I wonder if the amount of free storage matters?
Or perhaps you have a different chip than the others so far.
Interesting!
Excuse me for memory it's a false translation ;-)
I have 47 GB free on 64 GB of storage
When There are some app open in memory i have : storage write : 136 and storage read 199
