    You said you need 2+TB of storage. In a two disk mirrored RAID setup, if you use 1TB drives, you'll only have 1TB storage total (as the second will be an exact mirror of the first). So if your initial post is accurate, you'll need a 2x2TB RAID 1 setup.

    Edit: Unless you meant you need two separate 2x1TB RAID 1 drives... If so, disregard my post.

    If you want a mirror of those drives, usable capacity is that of one disk (1TB), so keep that in mind.

    You won't be able to use a mirror if you need access to more than that, unless you go with larger disks, which always remains 1/2 of the total capacity. It's just how a mirror works.

    And also note that a mirror is NOT a backup system. For example, if you make a mistake, it's duplicated automatically.

    Oh i have another drive that serves as a main backup. I just need the raid for my old stuff that i need to have mirrored.

    1tb is fine enough for me.

    Look here. It's a mirror only from what I can tell though, but with drives, it's not too expensive.
