So I am working on getting myself an external raid enclosure and moving my raid outboard, and I am faced with a decision. The outboard system will have its own controller, so I won't have any CPU penalty, so should I go raid 5 or 10? The array will be used to store media only, so mostly reads, writes should be at a minimum once its setup.
 
I am using 4x Samsung F1 1Tb drives
 
Thanks all.

    RAID 10 is recommended over RAID 5 since it gives speed and redundancy; basically RAID 0 and 1 together. The downside is that you lose half your HDD space.
     
    RAID 5 uses the parity bit, and you lose 1 HDD, but is more prone to failures.
     
    If I had to choose for storage, go for RAID 1 or 10.

    This site has nice gui also to help see various RAID levels.
    I hear nice things about RAID6 if you have the controller and drives to do one.

    Yea I have raid 10 now, I was just wondering if it was worth it to do raid 5 if I am offloading the parity calculations from the CPU. I think I will stick to my trusty raid 10. Thanks for your input guys.
