I am about ready to pull the trigger on a new MacPro and I would like some opinions on my two possible backup/RAID solutions. I was initially looking at hardware RAID but it is far too pricey and out of my budget. I will be using the built in software RAID and am planning on using WD Caviar Blacks. I don't do any professional work so high speeds aren't a necessity. I am leaning more towards the second setup for the fact that it offers a secondary backup of the Time Machine backup which contains versioned backups. Any constructive help would be appreciated!
Setup 1:
1TB System Drive: Holds OS & Personal Files
1TB Secondary Drive: Software RAID 1 Copy of System Drive
1TB Tertiary Drive: Time Machine Backup of System Drive
Setup 2:
1TB System Drive: Holds OS & Personal Files
1TB Secondary Drive: Time Machine Backup of System Drive
1TB Tertiary Drive: Software RAID 1 Copy of Time Machine Backup
Setup 1:
1TB System Drive: Holds OS & Personal Files
