need help with setting up a RAID

so as i was moving my stuff around i found an external 2tb hdd i bought a few months ago then lost. (dont ask me how i lost it). then got the bright idea to take it apart which revealed a 2tb WD green hdd. so i slapped it into my computer just now and re formated it. its working fine but id like to set it up in a raid but im not sure if i can since my other hard drive is a 1tb seagate barricuda, could some one fill me in if i can raid 2 different models of 2 different capacities? and if i can which raid would be the best? 0, 1, 3 etc..

  1. You don't need a RAID. Just set up some syncing software to sync a backup to it and put anything you want to survive through a drive failure on it.
  2. 1. Do not use a WD Green in a RAID 1 setup.
    2. Don't use two different size drives in a RAID 1 setup.

    Why?
    1. The WD Green spins up and down in an attempt to 'save energy'. The RAID function will suffer
    2. A RAID 1 depends on the size of the smallest. 1TB + 2TB = a 1TB RAID 1 array. And with the Green, a badly performing one.

    RAID 0 would be even worse.

    ok. would any other raids work at all? or the green just isnt a good one to use in a raid and the 2 different capacities make it even more useless?

    Those two drives will not work well together in any RAID scenario.

    And you do not need a RAID. You need a backup. Easily done, free, foolproof.
  5. very well then. ill skip with the raid on this set up. thanks for the input you two
  6. For a backup scenario, look at SyncBack Free.
    Point it at source and target folders, give it a schedule...done.
    Target drive here would be the WD Green.
