    Things you should know:

    • RAID-5 is good fault tolerance with good speed.
    • RAID-5 is three or more disks with parity data spread over all disks.
    • The total capacity of your RAID-5 array will be (Largest Disk x Number of Disks) - 1 Disk = Capacity
    • The maximum number of drives than can fail before RAID-5 fails is one. This is regardless of the number of drives present in your array.
    • RAID-5 is intended to be hot-swappable.
    • If a disk fails, you'll need to rebuild your array for it to be fault tolerant again. This takes many hours, typically.

    This is RAID-5 information.
    You may also want to consider RAID-50
