which is the better PCIe NVME SSD for my needs(running Ubuntu Linux)?

[Ashutosh_5]

I have Dell XPS 8930(Intel Core i7-8700 - 6 Cores with 32 GB RAM and 2 TB Hard drive with Optane). Want to have the PCIe NVME SSD for running dual boot Ubuntu Linux. Could very well have the SATA 3 SSD but i can have some more $$$ to have a slightly faster PCIe NVMe SSD.
I have checked my mother board - i have this slot:
x4 available.

Is this good one for my needs:

I would go with the Samsung 960 EVO, best of the three. I didn't check that your motherboard is compatible with PCIe M.2, but I assume that you did.
