software raid 1 fails

Hello, after many years I had my first failure on a server with software RAID 1, but that server was not defined the drive names as sda and sdb, cat /proc/mdstat shows that the first disk failed, to solve it, just replace it on the first disk reported or do I need to manually power off the failed disk for raid sync to be done?

cat /proc/mdstat:

fdisk -l shows:

RAID for home PC

I have 2 new HDD drives and I am thinking about making a ride array. I opted for RAID 1 because it is the most reliable one. It remains to choose now which method to use? BIOS or software (windows, linux)? I think that hardware raid is too much for home PC. What do you think?

Talking about the software RAID, if my Windows or Linux is broken my disk will be ok if I just reinstall the OS? The OS will be on NVMe, not HDD.
