RAID-10 If your controller supports it. If not, do it with Linux software RAID. RAID-1 will give you 1 x the drive size with data being written to all 4 disks at the same time, but being read from one - very redundant, but slow writes. RAID-5 will give you 3x your single disk capacity with one disk acting as a parity drive - reasonable performance, but one day you'll lose a drive and then find that a 2nd drive has sector errors when reconstructing the array and it's then game over - unless it's Linux software RAID and you're a guru - which you're not as you'd not be posting this question here. RAID-6 will give you 2x your drive capacity with the ability to survive 2 drive failling - hopefully you can replace one and not have bad sectors on another. RAID-10 will also give you 2x your drive capacity but has more performance than RAID-6. Not really an asterisk question though...
