    Any reliable source of what performance to expect from the different sizes of SSDs in the MBP15 2016? Especially interested if the 2TB could be faster than the 1TB as bigger SSDs are usually faster.

    Someone asked about this a few days ago, and no one had a any data to show much difference.

    Likely faster in any speed test, likely exactly the same in real world performance. They're lightning fast as it is, a couple of percent makes no difference.

    I started a thread asking owners to post their SSD benchmarks after noticing that the demo store machines had slower IO than my 2012 rMBP. Turns out the demo machines I saw were running significantly slower than they should have been and that owners' machines were flying. It was also clear that the larger SSDs were, in fact, faster than the smaller ones, but I doubt you'd notice the difference in real world use.

    Here's the thread I started

    The differences are probably smaller than appeared in that thread. 13" and 15" results were mixed together, though they use different storage, I've read. And there were too few samples. Notebook Check measured the 512 in the 15" at 2060 write, a good deal higher than was measured in your thread. More data would be interesting to see how big a difference there is.

    They are blazing fast in every machine since 2013 in most usages you will notice little difference but when moving huge files around a few seconds here or there may be noticed.

    Hello there,

    I tested 256GB version and 2TB version using blackmagic.

    The read speed all maxed out blackmagic's test at 2000MB/s

    The write speed is where the difference is,

    256GB got an average of 1300MB/s after 2 minutes of test.(Did multiple tests, the results are between 1300-1400)

    2T got an average of 1970MB/s after 2 minutes of test. (Did multiple tests, the results are between 1900-2000)

    Hope this helped you.
