My surface book 2 (15 inch, i7, 16G, 256G ssd) shows high read speed (~3000 mb/s), but super low write speed (~330 mb/s).  I returned my 1st one due to this super low write speed, but 2nd one also show almost same benchmark speed. Based on other reviews, these numbers are consistently reported in 256G ssd model. I wonder if this write speed is normal or it can be improved by firmware update later. If this write speed is normal...why MS used this ssd?. 300mb/s write speed is much slower than my 2yr old surface pro 4 256G (~1000mb/s) and 3yr old 256G ssd(~800mb/s) in my desktop....

    Really?!  What are your new read/write speeds?  Can you tell me where you got that driver? 

    Thanks a lot!

    My issue was that when running an SQL query, it took 30 seconds to run on my new i7 512Gb Surface Book 2, my old Surface Pro 3 took 9 seconds so something was really wrong here.  So I installed the Samsung NVE drive from here, had to go to Device Manager and manually update the 'Surface NVE Driver'  it and bang, now takes 3 seconds.

    I found by replacing the Surface NVE Driver with Samsungs driver, it cured my problem.

    I have the same problem with my 13 inches 256 SB2. high read speeds almost in the neighborhood of 2500 MB/s but almost unacceptable write speed (330 MB/s). I don't know the cause of this issue but I need a reasonable answer from the surface team.
