I just installed Win 10 Pro onto a machine that had Win 10 educational prior- a clean install. I have a C system drive and a 3-drive array setup as a single D: drive, consisting of 3 3TB single drives. I set this up 6 years ago and have no memory of what I did at that time but at present it shows up as 8+TB, so must have been RAID 0 . I want to reset the drive(s) as a RAID that will give me the fastest I/O without a need for backup/security (everything is backed up elsewhere) and don't need to retain any of the data currently on that drive set. Can someone give me a step by step? Thanks for the help.
