RAID1 - Mirroring

RAID1 is an implemention of drive mirroring, for every pair of drives (because RAID1 is done in pairs), the contents of DriveA is mirrored in real-time to DriveB
The advantage of RAID1 is that there is a very solid 1-level of Fault Tolerance (i.e., one drive can completely fail without any loss of data); the downside is that it is not very space efficient (drive capacity of a two-drive pair will be the size of the smaller of the two)
Since data is stored across both drives, read-performance will be (theoretically) twice that of the individual drive; write performance will be that of the slowest drive.
A minimum of two drives is required
