A RAID is an abbreviation, which stands for Redundant Array of Independent Disk. Its purpose is to combine multiple hard drives into one single storage volume.

Comments

  1. Is posible create internal Raid 1 ?? i have mac mini 2012. (4TB first slide and 4TB second slide)

    Thanks
  2. Thanks Great. Tutorial:=)
  3. Can i use this in raid 1 as a time machine backup drive until it is full; then simply archive those drives and replace them with new ones?
  4. Hi Erika, is there any warnings on bad hard drives before automatic rebuild?
  5. Raid 1 is NOT a suitable backup.
  6. hey erikai have question?
    i want to swap my hardrive in my macbook pro 2010 to a ssd
    i do music production so i have alot of licensing for plugins on my hard drive. i want to transfer everything over without having to uninstall everything and reinstall it on another hardrive. would raiding the hardrive be my best option for doing this?
  7. Ooops, Hi Charles I read your post after I erased the drives.... they work but I am using them for important data,...do I need to worry now?
  8. You do NOT want to erase the drives like Erika mentioned! Doing so under Yosemite will turn the drives into Logical Volume Groups/Logical Partition and you will effectively brick the drives.

    Partition the drives first, then you can erase the partition if you want.
  9. Hi Erika,
    What happens if you want to work on one drive and "update" the second drive using Raid 1? If the second disk is unmounted, will the changes update when you simply plug the second one back in? 
    Thanks!
  10. hi, im doing all you do in the tutorial but an error compare.
    Raid failure
    POSIX report: impossible to complete the operation, operazione non permessa
  11. I would like to use my raid for my movie collection. Should I use 256k block size?
  12. Great video - thank you. For the Google Drive backup setup, do you simply drag the Drive folder to the raid window as a second mirror drive, otherwise, can you elaborate?
  13. Hi Erika, thank you for the great tutorial!
    I have a few questions for you: 
    1) If one of the drives is unplugged from OSX for a short period of time, and a change is made on the other drive which is plugged in - will this cause an issue? Or will both drives simply sync up automatically when they are plugged back in together.
    2) Is it possible to use patricians of hard drives, rather then whole hard drives to employ this raid 1 mirror?
