Helping my parents build a new computer, I go online to look for installation instructions for Win10 on Raid 1, found this #cringe 😂 #LinuxFTW
After ten years in forums daily I've never seen a good outcome with RAID. Even a mirror or RAID1 designed to protect data if one drive fails, has always still resulted in the loss of all data.
With today's huge drives, real time backup and lightning fast SSD's there is no good reason for RAID except to learn the hard way.
