m.2 nvme raid 0

I just built a new m.2 drive and I am a bit confused with the number of pcie lanes that are available for my setup. Some say 16, some say 40. Some say that the CPU has 16 and the mobo has 40. This confuses me slightly.

My question is if I add another nvme drive into a raid 0 will it adversely affect performance? Or will there be any gain at all? I know how raid 0 works in theory and I have done sata raids before with great results.

I DO have all my data backed up so I am not concerned with the reliability of the raid 0.


Mobo: Gigabyte aorus z370 gaming 7
CPU: i7 8700k
Graphics: EVGA 1080 ti SC
Mem: Corsair Vengeance 2666

A name brand NVM-e SSD drive is very reliable. A good one will be guaranteed beyond the life of the machine. I have one in my ThinkPad.

I do not see value in RAID for SSD on a workstation computer or laptop. But it you want to do it, it should not hurt performance to a great extent.

Oh yeah i forgot to say that i have a Samsung 960 evo as my boot drive. It was more so for my personal knowledge. I see mixed reviews on the raid. I get 3.2 gig read/ 1.5 gig write speeds as of now. In the Sata SSD secondary drive RAID 0 that I have (because i have no life) I'm getting 1.4 gig read/ 700 meg write speeds.  I was just wondering if it would improve performance on the nvme as well. I probably won't do it though. I have already spent enough on this PC.

I use a single Samsung 960 in my ThinkPad as the single and large drive. Works great. Your speeds in this setup look fine.
