    Can someone tell me what 3 is? Lol

    "if default-bits-per-cell = 3 then that means you have TLC based NAND memory. If you have the TLC based memory then its possible you could have some issues down the road with your flash memory and it could even cause boot loops."

    According to this:

    MLC here, have Default-bits-per-cell = 2

    EDIT: I have a launch day model with MLC

    According to this SLC is better than both MLC and TLC. I can understand why based on the glass of water analogy.

    Well, to me as long as I don't have the TLC, I'm just fine. I don't need the best one, I just don't want the defective one. 😧

    Not sure if TLC is defective. It seems it's just not as efficient. I have no idea what's in my 6 Plus. No issues for me so far.

    Really wish I had been able to test the other two devices I'd had.

    I think that MLC is very stable though.

    The other thing to look at. Those that plan to get the 6 or 6+. How are you supposed to know what you have unless you buy it?
    I doubt the store will let you install the app to test it.
    And why is Apple building devices with different chips in each one?
    I plan on getting the 6+ in May, so I guess it will be a gamble.

    I wouldn't worry about it. If a user buys a 6 Plus or a 6 just and they find it unusable just return it.
    I'm not certain it's as cut and dry as to which type of nand is going to cause problems.
    I found the following:

    "SLC NAND flash is typically rated at about 100 k cycles (Samsung OneNAND KFW4G16Q2M)
    MLC NAND flash is typically rated at about 510 k cycles for medium-capacity applications (Samsung K9G8G08U0M) and 13 k cycles for high-capacity applications[citation needed]
    TLC NAND flash is typically rated at about 1 k cycles (Samsung 840)
    SLC floating-gate NOR flash has typical endurance rating of 100 k to 1 M cycles (Numonyx M58BW 100 k; Spansion S29CD016J 1,000 k)
    MLC floating-gate NOR flash has typical endurance rating of 100 k cycles (Numonyx J3 flash)
    However, by applying certain algorithms and design paradigms such as wear leveling and memory over-provisioning, the endurance of a storage system can be tuned to serve specific requirements.[45]"

    So I feel as these algorithms etc being applied to a certain chip could make it fine for what it's being used for.
    I'm sure there are iPhones 6's out there with TLC nand that are just fine.

    Are there any 6+, 128GB, with the MLC NAND?

    Buy it, open in store, install app. Find minor blemish or issue (Which you'll likely have), exchange device.

    However, if it has no issues at all, then just give it a chance. It says there are higher probabilities of TLC being defective. That doesn't mean they all are though.

    because apple can't get everything from one supplier. Same reason they had issues with screens on MacBooks a few years back. Samsung ones were good, but the ones used from LG were the ones causing issues. Seems pretty crappy if people get stuck with the "defective" ones. Hopefully apple would allow an exchange if people are having issues, and get rid of the "bad" units.

    It's not. The link in the first post installs a profile for the app. I'm not really interested enough to install apps from unknown entities. Not saying it is or is not legit. I am just careful what goes on my phone.
