As a best practice, which of the following RAID levels should NOT be used on an OS partition?

RAID 0 provides striping across multiple disks for performance but offers no fault tolerance or data redundancy, meaning a single disk failure will result in the complete loss of the operating system and all data on the array. For an OS partition, data integrity and availability are paramount, making RAID 0 unsuitable.

RAID 1 provides mirroring, creating an exact copy of data on two or more disks, which is an excellent choice for an OS partition due to its high fault tolerance and quick recovery from disk failure.

RAID 5 uses striping with parity, providing both performance benefits and fault tolerance for single disk failures, making it a viable option for an OS partition, though recovery can be slower than RAID 1.

RAID 6 uses striping with dual parity, allowing for tolerance of up to two simultaneous disk failures, which provides even greater fault tolerance than RAID 5 and is also a suitable option for an OS partition.
