Ponury Typ

Hi there mates. I have one simple question, how unraid is handling hdd data encryption ? I am almost sold on unraid but i need to know how it works (i was going to do similiar "stuff" under arch but since i saw unraid on linus yt i found that i can give it a try). The best solution would be that hdd are enrcypted until you type password during boot (i got kvm connection to server and instaled fail safe that kill ups connected to server so it would shot down serve in couple sek - yes i got offsite backup in case of hdd meltdown of this actions ) then they got decrypted. BTW Its not like i got illegal stuff on my server but i got shit tone of license, own work etc i dont want anyone to have in case they grab my server (data is worth couple times more than server it self).
