Q: New 12" Retina MacBook SSD speeds too slow ?

Just got my new Retina MacBook last week ! Very nice machine however It seems that the Flash Hard Drive Read write speeds are on the slow side. Specially when compared to the latest MacBook Pro numbers. Given this new Flash is NVM Express and Apple's own controller it should be much faster. The numbers I am getting are :

around 450 Mbps for Write and 750 Mbps for Read (screen shot attached). The new retina Pros are clocking at around 1400 Mbps !! Do my numbers for the new MacBook match other peoples experience with it as well or did I get a lemon ??

 

Thanks you

    I wouldn't exactly call no response for a year and a day, "fresh."

     

    And, I don't see how your response contributed anything to the OP's issue, but hey, knock yourself out.

    Those look like the specs for the MacBook Pro 13" Mid 2014 model, verify that your Model Indentifier is higher than 11,1:

    Look in this section and report back your model indentifier number:

    My reference source could be wrong, or may be that it's different for the i7 model, but clearly your ASP results should be correct:

    u see but now we need a person with i7 or 15" maybe there could be a difference...

     

    back to the topic

     

    both MacBooks of mine...  Macbook 12" 2015 and Pro 2015 has 5GT/s PCIe 2.0 x 4 ... why 1 has 1300 mb/s read and the other only 700 mb/s even though the 12" has 512GB storage and Pro has only 128GB

     

    Pro with 256 and more GB has even 1800 mb/s reads....

     

    Macbook 12" acts like PCIe 2.0 x 2 ... like 2014 Pro models... weird..

    If I had to guess, it would be because the cited MacBook Pro 2015 test was for not only the 15" model, but the optioned out 4 core i7 version, in lieu of the 2 core version.
