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 am returning my 2nd SB2 again, as I don't think I can get any update or resolution on this issue from Microsoft.

    That options is not checked for both device. I just enabled it and did benchmark, but same writing speed.

    BTW, what's you device? surface book 2? Is your SSD 256G? (or 512G, 1T)

    It is a SB2 15" 1TB

    I can't tell from the model number what drive it is.  If the letter F was actually a V it might be one of the PM 961 Samsung drives.

    Have you seen any firmware upgrades for the drive.  Samsung Magician should be able to let you know, but do not try to install one until you check back.

    The other thing is I had a drive which increased its speed if I disabled an anti-virus.  Make sure and do this while offline.

    The Dell systems use a M.@ NVMe drive with a SATA controller.  The way to check is to look in Device Manager under Storage Controllers and see if it shows SATA or Microsoft NVMe or Samsung NVMe.
