V310-15 new M.2 PCIe SSD lower speeds

Hello everybody! My laptop is V310-15isk (you can see the specs in signature) which according to the PSREF supports M.2 PCIe 3.0 x2 drives. So I:

1) updated bios very recently

2) got the brand new Western Digital SN500 M.2 and installed with the factory 2.5" HDD

3) made a clean W10 1903 installation (USB created with Rufus, UEFI boot)

4) updated Windows

5) updated drivers with Driver Easy and Driver Booster after W Update


However, I experience slow speeds with the SSD as you can see from the attached photos. The drive is recognized as one lane drive instead of two and thus, the lower speeds. Even the previous SATA 850 Evo had better benchmarks in 4K random read/write values (45/135). Does anyone have an idea on what is going on?

Hi! The machine is compatible with the WIndows 10 1903 update so could you try running the update from the Lenovo Vantage app. You can get the app here: Install all available update.
