Need help with RAID-1 (data mirroring )

  1. Hi,

    I am ordering a new Dell system with Raid-1 but not sure of Raid-1's pros & cons.

    The main reason is data security. But few questions.

    (1) Currently I clone my HDD twice a week as a back up using Acronis True Image software. Could I still do that by removing one of the Raid 1 drive OR the Raid -1 configuration will duplicate the new 3rd drive when I remove the 2nd drive ?

    (2) Could I remove the Raid -1 configuration in case if I don't like it for any reasons ? In that case could I continue on cloning the drive as I am doing currently using Acronis ?

    (3) Any other pros or cons ?

    Thank You.

    The downside to RAID 1 would be slower performance (multiple writes) and if something is corrupted or damaged on drive 1 that change will be made to drive 2.

    You should be able to break the mirror without any issues. If you want to duplicate a drive with Acronis, you should still be able to do that while the mirror is in place as long as acronis can access the RAID drives. I would suggest either adding a internal drive to store the images or using an external drive.
