    Tested and is faster as well. I have a TLC 128gb by Sandisk. Read Write is definitely slower than the regular iPhone 6 64gb with a MLC. Should I change it? It seems I had a few crashes here and there incl microphone problems and camera.. but hate to setup everything again for my office (VPN, security certificates, database etc etc...) It does seems a little slower..

    I am sorry, but what is TLC and MLC? I google it and it comes a music band, an electrical supplies shop and and anime called The Lost Canvas.

    It is the type of flash memory used in iPhones. The larger storage capacities were using TLC as it is cheaper, but apparently has been causing issues. I believe Apple was planning to move to MLC to resolve these crashing issues users were having.

    curious how you are able to tell the difference without tearing the phone apart. i'm not aware of any programs that will show you the actual NAND type used in the phone

    Good app! Just bought it.

    I have 274 write, 751 read on my iPhone 6 128GB (not plus).

    Then you have MLC.

    Also, no evidence at this point suggest Apple has switched to MLC from TLC for the 128GB models, so exchanging now doesn't mean you'lll get MLC. Defintely exchange if you're having actual issues like boot-looping, but IF a switch is actually going to happen, it's going to take a few weeks for the supply chain to be fully converted.

    Current rumor also suggests ioS 8.1.1 has a software based fix.

    It is not confirmed at all if it is actually related to the NAND , it could very well be just how iOS handles file systems that large

    How do you know that from the readings? Thanks.

    You better replace TLC device with MLC device.

    1) TLC device read/write low performance

    If the image is not shown, check this URL: http://www.kbench.com/?q=node/142414 HK tech news had done a test and Korean Benchmark news reported.

    2) approximately 1/10 lifespan

    Chinese geeks made a tool for identifying which memory the device has in it. I myself didn't try yet because I don't have the new iPhone.

    Don't believe the test results from phone doctor too much. It can't distinguish the actual writing on memory from RAM and the caching from RAM. That's why sometimes writing is seemingly faster with TLC than with MLC. It's just what Apple wanted to be shown like using cache memory trick.
