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.
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.
