Some RAID 1 implementations treat arrays with more than two disks differently, creating a non-standard RAID level known as RAID 1E. In RAID 1, one of the drives is used to store the data and another one acts as a mirror to the already stored data. We can easily manage our hard disks from the web management UI. Few of the things I am passionate about include system administration, computer hardware and physics. Say you have 3x8TB drives in multiple locations and want the max amount of profit, in 5 years you’ll benefit from redundancy (raid5/z1) only if drives are so bad that you lose 5% of drives every year and never replace them. RAIDZ1 maximizes disk space and generally performs well when data is written and read in large chunks (128K or more). This provides significant reliability in case one drive fails - you don't have to reconfigure a fresh FreeNAS install from scratch. Now select the Raid Type like Stripe, Mirror, Raid-z, and Raid-z2.
