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.
