Can i Use the M2 card or Nvme disk for booting the UNRAID instead of pendrive or usb disk ?

No, the USB flash drive is required for licensing.

 

None of the OS is installed to any of your storage.

 

The OS is unpacked fresh from archives on the flash drive, into RAM, at each boot, and the OS runs completely in RAM. Think of it as firmware.

 

The flash drive also saves settings you make from the webUI in the config folder so your configuration can be reapplied at boot.

 

Other than that, the flash drive isn't accessed much.

is this processor is good for NAS on UNRAID?

That depends on how you intend to use Unraid.  There a many potential uses some of which require more powerful hardware.

• NAS only serving up files on shared storage to external clients?  The Celeron would be fine for this.
• Plex (or other media server) server with occasional transcoding needs?  You would likely want at least an i3 CPU for this
• Host some Docker containers for backup, media downloading, media server, network management, etc. in addition to the above? Again, likely at least an i3/i5 and maybe more depending on how you use Docker
• VM host for one or more VMs?  You would likely want at least an i7 with a fair amount of RAM for dedicating CPU cores and RAM to VMs. 

Decide first what you want to do with Unraid and that will help make the hardware decision easier.  It is always good to have some headroom to grow as you will probably find more uses for Unraid than you initially anticipate.

 

Enable signatures in your forum account settings.  Many users put their Unraid hardware specs in their signature and it will give you an idea what other are using.
