    RAID question

    There are something’s which tasks the minds of everybody regardless of their stature of intelligence. I believe it’s either called a senior moment or having a blonde moment...? (Nothing against blondes mind, my misses is blonde.)

    Question I have three HDDs in my system, and I want to use the two identical HDD as RAID and the other for backups and application storage? I think you can run two HDD as RAID and the other as a single HDD. RAID 0 would be all three but would require another HDD to make a mirror. RAID 1 you can use two HDD as RAID and the single would not be a RAID which is what I require. I’m 99.9% this can be done but I’m asking just in case.
    Thank you

    RAID 1 is what you want, you were right with your initial thoughts.

    Not sure what you mean. RAID 0 can be done with any number of drives (with the correct controller) and isn't mirrored.

    There are no problems with creating an array from 2 of the drives and keeping the last drive on it own. You have 2 choices for the type of RAID array you can create from 2 drives.
    RAID 0 - This will give you 2 times the capacity of one drive (becuase there are 2 drives) and it will give you better performance, in general anyway. RAID performance characteristics are quite complex and much debated. It will also mean that if one drive fails you will lose ALL of the data that was on either disk.

    RAID 1 - This will give you the same capacity as one drive. Performance for a single user is no different to having a single drive. The advantage is that if one drive fails everything will carry on.
