A redundant array of independent disks, or RAID, is a way of storing
the same data in different places (where the term redundant comes from)
on multiple hard disks.
There are many ways to use RAID and there are several different types of array. Some use multiple disks to increase performance – think a two or three lane road instead of single, that has to serve traffic going in two directions – while others are used to increase reliability. Additionally, there is a third type of RAID that offer the best of both worlds; all of which we’ve explained below.
A RAID array appears to the operating system to be a single logical drive, regardless of how many individual drives are part of the RAID array. Both hard disks and SSDs can be used, and while it’s advised that matching drives are used in a single array for best performance, it’s not strictly required.
