- BMinimum of five drives

Explanation
Migrating from RAID 1 to RAID 5 requires adding at least one additional drive, so having sufficient unused drive space or an available drive slot is the fundamental prerequisite.
Common mistakes.
- B. RAID 5 requires a minimum of three drives, not five; five drives would be required for RAID 6 with double parity or certain other configurations, but not for a basic RAID 5 migration.
- C. HP ORCA is a specific HP server utility for configuring arrays during boot and is not a universal or mandatory requirement for migrating a RAID volume across all platforms and controllers.
- D. A minimum of 2 GB RAID cache memory is not a defined universal requirement for a RAID 1 to RAID 5 migration and is a controller-specific optional performance feature.
