SSD & 2 Hard Drives RAID 1, Ok?

Doing a new build with an SSD and 2 hard drives with Windows 8.1. I will put OS on SSD. I will put the hard drives in RAID 1.

Is this ok and any advice?

  1. why are you doing raid 1? Raid is not a backup.
  2. I don't have experience with RAID, but the store rep and what I have read is that RAID 1 is the level that makes an exact copy on both drives - is that not a backup or is this incorrect?

    RAID 0, is the only level I think that is without backup.

    RAID 1 is a mirror, not a backup. There is a difference.
    Yes, it mirrors everything on the two drives.
    It also faithfully mirrors every accidental deletion, virus, file corruption.

    An actual backup saves you from those worries.

    A business might run a RAID 1, so they can stay up and running if a drive dies. They also have an actual backup.
  4. Wouldn't that be true of all RAID levels except 0?

    I'm going to use cloud backups.

    Yes.
    Delete a file on my drive, it's deleted.
    Delete it with a RAID 1, it is the exact same result. Just deleted from 2 drives.

    If you're going to have backups elsewhere, the RAID is really, really not needed.

    If I have a few applications installed on a secondary drive, and it dies....no problem. I still have the install disks and can redo it in an hour. If I were running a webstore or something, that hour to rebuild translates into lost sales. $$$.
    But for me here at home? Trivial.

    The extra hassle is not worth it.
  6. Thank you that is what I needed, but it leaves me with another question.

    The hard drives and should I put them in RAID 0 to increase performance? Or install as two drives (3TB each)?

    I wouldn't RAID 0 them. With a 0, fail of either drive, or the RAID info = all data is lost.
    Since you're going to have an SSD, (OS and most applications), super zippy performance out of the data living on the HDDs is of no real concern. If I'm running a playlist of music from the HDD, it wouldn't play any faster if living in a RAID array.

    You can try it as a hobby. But it's really not needed. I'd just have them as two individual drives.
  8. Great - thanks!
  9. Good luck with the new SSD !
