Create a RAID array
- [Instructor] Hard drives are generally pretty reliable, but for highly available configurations and for storing data, it's nice to be able to increase the reliability of our storage even further. To do this, we can combine more than one disk to reduce the risk of failure of single devices. The technology that allows us to do this is called RAID, which stands for Redundant Array of Independent Disks. RAID lets us combine separate physical disks into arrays, or configurations, where data is split apart and stored across more than one device in particular ways. This is called striping, in that pieces of data are written in stripes across different physical drives. Some configurations of RAID provide improvements in read or write speed. But in many cases nowadays, we use RAID for redundancy more so than speed. Improved caches and different technologies like solid state storage take up a lot of the slack for speed related issues. The arrays we create can store data in different ways, and…
