    It's great to see innovations/advancements like this, still been achieved!

    Not sure if 33% extra capacity is worth losing 70% endurance compared to TLC
    Only 1000 P/E cycles sounds really scary for an SSD

    However, this would work for USB sticks, memory cards and other devices which don't rewrite that often.

    Regular usage should be pretty OK even if it sounds like a lot, constant read/write with a massive amount of data and the drives still lasted a really long time from what I recall of the test that done for this purpose against a number of drives a year or two back.

    Guessing it's the same as HDD's though and some drives can be more prone to error or failure and this does improve capacity while keeping prices at a somewhat lower level but I guess testing will have to check just how durable QLC will be against TLC.
    (Though it might still give a number of years for standard usage.)

    EDIT: So SLC for single layer cell, DLC for double layer cell or rather MLC and now TLC and QLC.

    PLC next then and five layers? 100 cycles?

    I Remeber 8 years ago talk of 1TB SSD costing $100 by 2018.

    Were barely at 512GB costing $100.

    I once did the math and my MLC SSD would take 16 years to die from use.
    I'm sure I will switch to something faster/bigger before, but for more heavy usage I'd guess that 10k cycles would be the minimum endurance.
    1k cycles sounds scary alright, but we are talking 2 to 8 TB drives that will probably be used to store data and not be rewritten very often.
    If the price was the same as an HDD I'd rather buy the faster SSD for data storage.
    As for endurance, I'd prefer the TLC for daily usage.

    In MO The SSD manufacture technology is surely going backward, instead of going forward like any other part of the PC industry. The SSD's are getting slower and less reliable , only to make higher profit margin for the companies that make them.
    That is in great favor for the NAND Flash Manufacturers and really bad for the people who buy SSD's

    That's warranty endurance, not actual. Top TLC chips are able to withstand over 20000 PE cycles.

    The main question is will it able to withstand 1-month power-off vacation period after even 1000 PE cycles?
