Slow NVMe SSD Write speed

[kaiteck]

Hi guys, i just bought a new laptop which uses NVMe ssd which rated read speed around 1.5GBps.
But for some reason, I'm getting 150MB/s for write speed, is this normal? Or am I missing out any drivers coz I just installed Windows 10 pro english to it.

I attached a screenshot of AS SSD benchmark

It's possible your motherboard doesn't have a PCIe 3.0 x4 slot. If it only has a PCIe 2.0 x 4, that would make sense as to your speeds. Please supply your motherboard model and we might be able to help more.

Mi notebook 13.3"

I've a feeling its the ssd model. I've checked the specs of my NVMe Samsung MZVLV256 on this site: http://www.samsung.com/semiconductor/products/flash-storage/client-ssd/MZVLV256HCHP?ia=831

It stated Sequential Write Up to 280MB/s..!

But 280MB/s is still far from my benchmark test 149MB/s.. is this normal?
