In building my new desktop, I currently have a 1TB NVMe for the OS, a 2 TB NVMe for games and apps, and an 8 TB HDD for data (mostly photos/videos/movies). I'm wondering if it's worth mirroring the OS drive? The other drives I'm comfortable with just backup, as that is easy enough, but I've had some bad experiences recently with OS drive problems... Is it worth doing? Do you use Raid on your own machines, if so, for what?
