A systems administrator is provisioning a SQL server with a RAID controller. The management team requires that the server be able to withstand at least a single hard drive failure, but the…

RAID 0 provides no data redundancy and will result in data loss if any single hard drive fails, failing to meet the requirement for single drive failure tolerance.

RAID 5 offers single disk failure tolerance but involves parity calculations, which can be computationally intensive and may reduce write performance for a SQL server compared to RAID 10.

RAID 10 (also known as RAID 1+0) combines mirroring (RAID 1) and striping (RAID 0), offering both fault tolerance against single drive failures and high performance for database operations. It avoids the performance overhead of parity calculations present in RAID 5 and 6, making it suitable for computationally intensive workloads like SQL servers.

RAID 50 is a nested RAID level (RAID 0 of RAID 5) that provides good performance and fault tolerance but still relies on parity, making it more computationally intensive than RAID 10.

RAID 60 is a nested RAID level (RAID 0 of RAID 6) offering high fault tolerance but is the most computationally intensive due to double parity, which would significantly impact performance.
