A new server has recently been purchased and needs to have the RAID configured for its four drives. Which of the following RAID levels would be set up to provide the BEST performance and data…

RAID 0 stripes data across drives for maximum performance but includes no redundancy or parity, meaning any single drive failure results in total data loss.

RAID 1 mirrors data between drives providing strong redundancy but offers no performance improvement from striping, and with four drives it wastes 50% of capacity compared to RAID 5.

RAID 4 uses a single dedicated parity drive which creates a write bottleneck since every write operation must update the dedicated parity disk; RAID 5 resolves this by distributing parity.

RAID 5 distributes parity information across all member drives rather than dedicating a single parity disk, which eliminates I/O bottlenecks and provides both improved read performance through striping and fault tolerance allowing recovery from one failed drive. With four drives, RAID 5 uses three drives' worth of capacity for data and one drive's worth for parity, making it the most efficient combination of performance and protection available in this scenario.
