Surface book 2 15 inch 256G super low wirte speed

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....

    I have the same problem, write speeds reaching a maximum of 340 MB/s. I am not happy about this and I'm becoming impatient.

    Will Microsoft go into denial like Apple? No solutions on offer?

    Same problem here, would like an update from a Microsoft official if this is expected behavior.

    Same issue here but with the SB 2 13" i7 w/ 256GB Drive.  Very disappointing.  Saving large files takes three times as long as on a 3 year old machine that I had prior to this.  These are pathetic speeds for a NVME SSD.  My machine is completely up to date and I just reloaded Windows to see if it would make any difference.  

    Does anyone have a 256GB drive with valid write speeds?

    Hi All

    Funny enough I contacted Amazon support in regards to this issue and the representative told me that this is the first time they hear about this issue. And as I purchased the SB2 15 256 via Amazon they suggested to get it replaced so i did, but I bet replacement will also have slow W speed
