I'm setting up a new computer and have never used a raid config I have a 1tb nvme m2 drive and access to 1tb, 2tb, and 8tb hdds.

So the question is can I run raid 1 with the 2 1tb drives to have a complete backup in case of nvme failure?

Or should I just keep important files on hdd and run ahci?

Another option maybe, partition one of the larger drives and raid 1 there?

1. RAID is not a backup
2. No, you cannot do a RAID 1 with those drives. Well, you can, but you really, really, really do not want to.
3. RAID is not a backup.

A RAID 1 gives you the size of the smallest drive in the array, and the speed of the slowest.
The NVMe drive would be continually waiting for the HDD to catch up.

RAID is not a backup.
It can help in one and only one condition...a dead drive. It does nothing for the far more likely ways for your data to disappear.
Accidental deletion, virus, corruption, ransomeware, etc, etc.


A far, far better method is to use one of the current imaging tools, and set up a schedule to create images to the 8TB drive.
For instance, Macrium Reflect will do an image, on whatever schedule...

No. Raid should be with identical types of drives. Load everything on the SSD and use a free software backup utility to protect important files.

RAID is not a backup - it is purely about higher availability. If you delete a file in raid 1 it's gone on both drives.

For instance, Macrium Reflect will do an image, on whatever schedule you select, to a folder on that 8TB.
In case of need, put in a new NVMe drive, and resurrect that image back to the new drive.
