A systems administrator is configuring RAID for a new server.
This server will host files for users and replicate to an identical server.
While redundancy is necessary, the most important need is to maximize storage.
Which of the following RAID types should the administrator choose?

RAID (Redundant Array of Independent Disks) is a technology used to combine multiple hard disk drives (HDDs) or solid-state drives (SSDs) into a single logical unit to improve performance, reliability, or a combination of both. RAID levels determine how the data is distributed and stored across the disks.
RAID 5 is a level of RAID that stripes data and parity information across three or more drives. It provides good performance and redundancy but requires at least three drives. However, it uses only one disk for parity information, which means that if a disk fails, the data can still be reconstructed. RAID 6 is similar to RAID 5 but uses two disks for parity information, providing greater redundancy but requiring at least four drives.
RAID 50 is a combination of RAID 5 and RAID 0. It stripes data across RAID 5 arrays and uses RAID 0 for the striped data. RAID 50 provides better performance than RAID 5 or RAID 6, but it requires at least six drives and has higher complexity.
RAID 10 is a combination of RAID 1 and RAID 0. It mirrors two identical RAID 0 arrays. Data is striped across the RAID 0 arrays, and each array has a duplicate copy on the other array. RAID 10 provides good performance and redundancy and requires at least four drives, but it uses half the available drives for redundancy.
In the given scenario, the most important need is to maximize storage while maintaining redundancy. RAID 10 provides a good balance between storage capacity and redundancy, and it is well-suited for hosting files and replicating to an identical server. Therefore, the correct answer is C. 10.
