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. &nbsp;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.

You are very welcome and I was happy to help you.

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

Windows 10 is a personal computer operating system featuring the "universal application architecture" (UAP); apps can be designed to run across multiple devices with nearly identical code, including PCs, tablets, smartphones, embedded systems, Xbox One, Surface Hub and HoloLens. Windows 10 also includes a virtual desktop system, a window and desktop management feature called Task View, the Microsoft Edge web browser, support for fingerprint and face recognition login, voice-based search (Cortana), new security features for enterprise environments, and DirectX 12 and WDDM 2.0 to improve the operating system's graphics capabilities for games.

RAID stands for Redundant Array of Independent Disks.

RAID is data storage technology that allows multiple drives to be used together as a single virtual drive for reasons such as fault tolerance, reliability and performance. 

There are several different levels of RAID that determine how the data is stored and the level of redundancy achieved across the drives.

RAID

Hardware includes cell phones and other digital living devices, tablets, computers, servers, peripherals and components, printers and scanners, gaming consoles, networking hardware such as routers, hubs, switches and modems, storage devices and security equipment such as firewalls and other appliances.

Computer data storage, often called storage or memory, is a technology consisting of computer components and recording media used to retain digital data. In addition to local storage devices like CD and DVD readers, hard drives and flash drives, solid state drives can hold enormous amounts of data in a very small device. Cloud services and other new forms of remote storage also add to the capacity of devices and their ability to access more data without building additional data storage into a device.
