    Hi All,

    I have a late 2013 27incher with a 3TB fusion drive (that is now split).
    I wonder what speeds you are getting with blackmagic disk tester; for me it's ~700 read and 300+ write.

    I'm lead to believe that there is something going wrong with write speeds, because I also replaced the hdd with a kingston v300 ssd, and that one is also exhibiting low write speeds (480 read v. 210 write). Two ssds with significantly lower write speeds can't be a coincidence, can it?


    PS: I was getting same 700/300 speeds back when it was still fusioned.

    No as it's only a 128Gb disk that is the max write speed you will get it is no higher until you have more silicon on there I'm afraid, those were the speeds all the 128Gb ssd's apple used in that year got.
