    anyone know the 2017 SSD speed vs 2016? I know they said it was faster but wondering how much faster.

    This year the SSD is just downgrade from 19nm to 15nm NAND chip according by ifixit tear down, as Apple just increase the internal lands from 2x to 4x and claim that faster.

    If it's actually faster, as benchmarks seem to indicate it is, what does it matter?

    This good for marketing on benchmark, but for real performance not too much help, even read/write large file you can not see too much different unless the SSD is new.

    1. The speed of sequence read/write is actually fast enough and don't help a lot in real performance, and just affect very rarely internal large file copy , the faster speed hard to achieve because because copy from external is restricted by USB 3.0 speed.

    2. The small file read/write and latency will increase due to worst NAND, it affect the response of the OS, such as Safari read/write cache.

    3. The reliability and endurance will reduced.

    4. The heat of controller and NAND chip will increase and the speed will reduced due to heat.

    5. The GOOD is Apple reduced the Cost (and sale it some price)
