* RAID 5 configuration: Using five of the available drives in a RAID 5 configuration meets the requirements for: * Storage capacity: Four 600GB drives (2, 5, and 6) provide a total usable capacity of 2.4TB (4 * 600 * 0.8), exceeding the minimum requirement of 2TB. RAID 5 introduces parity data for fault tolerance, sacrificing some usable space (one drive's worth). * Performance: The combination of multiple drives in a RAID 5 array improves read performance compared to a single drive setup. * Fault tolerance: Even with a single drive failure (any of the five drives used in the RAID 5), the remaining drives can reconstruct the lost data, allowing the server to continue operating.
