Raid

So you want to create a RAID 0 (striped) volume using the 2 M.2 NVME drives and use it to boot your OS (Windows).

Is that correct?

Alright, there is a solution,
but is there reason you want to create a RAID 0 volume on M.2 drives?

Depending on the M.2 drive manufacturer, they are fast; if creating a RAID 0 volume using old HDD for better R&W speed, it makes since. But accomplishing RAID 0 on 2 M.2 drives for faster R&W for booting OS and playing games, I would just keep the OS drive and games storage separate. In case if OS drive gets corrupted you can still keep the games storage left intact without worrying about virus issue. But no drives are always safe.

RAID 0, as you know there is no redundancy if one drive fails. Safe to create a RAID 5 parity volume.

There is a catch as well, UEFI does not support RAID 0 volume, so you cannot install OS if the UEFI is enabled on BIOS.

So the following must be configured and met.

* BIOS must be set to legacy settings (no UEFI)
* RAID volume cannot be more than 2 TB
* Fast boot must be (maybe)

Still want to learn more?

I'm not sure how to configure RAID 0 in BIOS menu, but I'll go through the steps by using the DISKPART cmd prompt.

First: BIOS settings and your motherboard is compatible to create M.2 RAID volume
Since I do not know what your BIOS menu looks you'll have to try configure the followings by using the references from internet
* BIOS "legacy" settings
* SATA mode: RAID

Save your BIOS changes and restart the PC

Confirm with your laptop manufacturer that the motherboard M.2 drives are compatible of creating RAID volumes.

Second: Checking the M.2 drives are added onto the motherboard with combined total storage capacity less than 2 TB.

Third: Boot up your Windows installation CD

1. Boot off from your Windows installation CD
2. Once at the installation menu, press Shift + F10 to open cmd prompt

Fourth: DISKPART
CAUTION: Careful how you use DISKPART cmd prompts. if you have other drives in your laptop and if you accidently select the wrong disk / drive you can accidently do work on a disk / drive which you did not wanted. So double check that you have selected the correct disk / drive before proceeding anything.

1. Once the cmd prompt is opened type DISKPART

> DISKPART

2. Check all the disks / drives connected to you pc

> list disk

You will see something like the following screen (if you have no other drives connected)

Disk ### Status Size Free Dyn Gpt
-------- ---------- ------- ------- --- ---
Disk 0 Online 1000 GB 0 B
Disk 1 Online 1000 GB 0 B

3. Select the disk by the following; 'n' is the disk / drive number (do not include '')
NOTE: you will repeat this cmd many times for precaution

> select disk 'n'

To confirm you have selected the correct disk, type list disk again, this time you will see a '*' next to a row of disk which you have selected, if you have selected Disk 0, you will see something like this

Disk ### Status Size Free Dyn Gpt
-------- ---------- ------- ------- --- ---
* Disk 0 Online 1000 GB 0 B
Disk 1 Online 1000 GB 0 B

4. Convert each disk to dynamic

Action the following commands one at a time for each disk / drive

> clean
> convert dynamic

Once the commands for each drives are complete, check that the drives are coverted to DYN

> list disk

You will see something like the following screen

Disk ### Status Size Free Dyn Gpt
-------- ---------- ------- ------- --- ---
Disk 0 Online 1000 GB 0 B *
Disk 1 Online 1000 GB 0 B *

5. Create volume for each disk and stripe

> create volume stripe=0,1

This should do it, the above command can time to complete.
After the RAID 0 volume is created, you can check your new RAID 0 stripe volume by typing the following

> list volume

6. Exit DISKPART

Press Ctrl + C to exit out of diskpart and type exit on cmd prompt

DISKPART cmd prompt scripting is a great tool to use. The above is just 1 of many ways to creating RAID volumes. Check out Google references on the followings.

* DISKPART
* RAID 0 cmd prompt

Good luck and have fun
