WHAT IS RAID 10 ?
RAID 10, also known as RAID 1+0, combines disk mirroring to protect data and disk striping to create a larger array of data. A RAID 10configuration requires a minimum of four disks, and stripes data across mirrored pairs. As long as one disk in each mirrored pair is functional, data can be retrieved.
