RAID 1 is costly primarily because it requires duplicating all data across two or more drives, effectively halving the usable storage capacity. For example, if you have two 1TB drives in a RAID 1 configuration, only 1TB of usable storage is available. Additionally, the need for additional hardware, such as extra drives and potentially more advanced RAID controllers, can further elevate costs. This redundancy, while providing data protection, translates into higher overall expenses compared to other RAID levels that utilize more efficient storage methods.
RAID level 1
Such level of redundancy is called RAID 1 and nowadays is used mostly in consumer level computers.
RAID 1, RAID 1 + 0, and RAID 5, 6.
Every RAID level stripes data across multiple drives, which improves performance compared to using a single disk. RAID 0, RAID 1, RAID 1+0, RAID 5, RAID 6, etc. all have better performance than a single disk. Other than RAID 0, all other RAID levels provide fault tolerance. RAID 1, RAID 1+0, RAID 5, RAID 6, etc. all have fault tolerance.
RAID 1
RAID 1 OR RAID 5 provide added performance as well as fault tolerance --- GAURAV TOMAR
That would be RAID 1.
RAID 1 is the most fault tolerant, as all drives have to fail to lose data.

Raid level 5 supports reading and writing, but writing performance is slower than raid levels 0 and 1.Raid level 5 requires a minimum of 3 drives.
