If one disk gets fried, the other can keep working. It’s the simplest way to implement fault tolerance and it’s relatively low cost.The downside is that RAID 1causes a slight drag on performance. RAID 1 can be implemented through either software or hardware. A minimum of two disks is required for RAID 1 hardwareimplementations. With software RAID 1, instead of two physical disks, data can be mirrored between volumes on a single disk. One additional point to remember isthat RAID 1 cuts total disk capacity in half: If a server with two 1TB drives is con ! gured with RAID 1, then total storage capacity will be 1TB not 2TB.Following are the key points to remember for RAID level 1 .Minimum 2 disks.Good performance ( no striping. no parity ).Excellent redundancy ( as blocks are mirrored ).
