Enable RAID support, Network Port + Thinkpad Keyboard

Thanks for the detailed reply

I wanted to refer to mirrored disk setup (RAID1), but I goofed up

You are right RAID1 can be setup with current version aswell but with lower SATA speeds which is a huge drawback

I would like to have two PICe ports instead of the SATA port so that we get the speed & redundancy without compromising on the speed. Not sure if there are any technical limitations to enable 2 PCIe ports

Do we need backup even after having RAID1 setup? I dont take backups

Off topic:
Appreciate if you can point me in the direction incase if backups are also required
