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?
Correct Answer: A. RAID 5
RAID 5 offers a balance of redundancy and storage efficiency, making it ideal for scenarios where maximizing storage is a priority. It uses striping with parity, allowing data to be distributed across all drives with one drive's worth of space reserved for parity. This means usable storage is approximately the total capacity minus one drive, while still providing protection against a single drive failure—making it a strong choice for file hosting with redundancy.
Why Other Options are Incorrect:
B. RAID 6
RAID 6 provides dual parity, allowing for two drive failures, which improves redundancy. However, it uses more storage for parity (two drives’ worth), reducing overall usable space—making it less ideal when maximizing storage is the primary concern.
C. RAID 10
RAID 10 offers excellent performance and redundancy through mirroring and striping, but it sacrifices 50% of total storage capacity due to mirroring. While highly reliable, it does not maximize usable space compared to RAID 5.
D. RAID 50
RAID 50 combines RAID 5 and RAID 0, offering higher performance and fault tolerance, but requires more drives and reserves more space for parity. It provides good redundancy but does not maximize storage as efficiently as standalone RAID 5.
