This one.
Microsoft has more than 100,000 programmers employed. The problem is that at this point the source code of Windows is so large that they had to modify Git to be able to even work on it.

Sigh.. this is bugging me:
MP33 M.2 PCIe SSD using NVMe 1.3 protocol:
https://www.teamgroupinc.com/en/upload/product_note_pic/c5b68811632bdcc2e516ca197fe7bf1d.jpg
Read and Write should be 1,800 MBP/s.
I am getting 800 MBPS both read and write. :\. See my benchmark:

MSI B350 Tomahawk (AMD). See CPUz ID for more info:

Thanks.
I may have a working theory behind this. Currently, I am using PCI-e adapter for NVM-e until I get some spart parts (screws) for my NVMe on my motherboard. A NVMe slot is a dedicated lane to the CPU unlike PCI-e x8/x16 slots? This might explains why I am only seeing 800 MBP/s.

Update. After doing some research, I found out that my secondary PCIe slot is operating 2.0 x2 bandwidth which is 800 MBP/s because one of 2.0 x4 slot was used (PCIe x1). So I took it off and my speed was at (R): 1,400 MBP/s and (W): 500 MBP/s. I find that very odd because 1) with PCIe x1 in use, it operates both R/W at 800 MBP/s. By making PCIe x1 slot available, write speed seems to be a lot slower, but the read speed doubles. I wondered why.
It wouldn't really matter because PCIe slots are on shared lanes anyways. M.2 is on dedicated lane, correct me if I am wrong. I will find out on the 29th once the correct screws for M.2 NVMe board arrives from MSI.
