RAID1 is used for fault tolerance and requires only two drives as it mirrors the data onto both drives, providing redundancy in case one drive fails. RAID0 does not offer fault tolerance and requires a minimum of two drives, but it stripes the data across both drives, increasing performance but increasing the risk of data loss if one drive fails. RAID5 requires a minimum of three drives and provides both fault tolerance and increased performance, but can be slower for write operations. RAID10 (also called RAID1+0) requires a minimum of four drives and combines disk mirroring (RAID1) and disk striping (RAID0) to provide both fault tolerance and increased performance, but can be more expensive and complex to manage.
