A technician is commissioning a workstation that is required to have mirrored storage, utilizing two 4TB drives that support one failure. Which of the following best meets these requirements?

Rationale

RAID 1 best meets the requirements for mirrored storage utilizing two 4TB drives that support one failure.

RAID 1 provides data redundancy by mirroring the data across two drives, ensuring that if one drive fails, the other can continue to function without data loss. This setup aligns perfectly with the requirement for mirrored storage and the ability to withstand one drive failure.

A (RAID 0) YOUR ANSWER

RAID 0 offers improved performance by striping data across multiple drives, but it does not provide any redundancy. If one drive fails, all data is lost since there is no mirroring or parity. Therefore, RAID 0 does not meet the requirement of supporting one failure.

B (RAID 1) CORRECT

RAID 1 is the ideal solution for this scenario, as it mirrors data across two identical drives. With two 4TB drives, the total usable storage is 4TB, but the configuration supports the failure of one drive without any data loss. This redundancy is crucial for maintaining data integrity.

C (RAID 5) YOUR ANSWER

RAID 5 requires a minimum of three drives and uses one drive's worth of space for parity, allowing for the failure of one drive while still retaining data. However, it does not fulfill the requirement of utilizing only two drives, making it unsuitable for this specific scenario.

D (RAID 10) YOUR ANSWER

RAID 10 combines the features of RAID 1 and RAID 0 by creating mirrored pairs and then striping across them. While it provides redundancy and performance benefits, it requires a minimum of four drives, making it impractical for a setup with only two 4TB drives.

Conclusion

For the given requirements of mirrored storage with two drives that can withstand one failure, RAID 1 is the most suitable configuration. It effectively mirrors data between the two 4TB drives, ensuring data availability in the event of a drive failure, while other RAID levels either do not provide adequate redundancy or cannot operate with the specified number of drives.

RAID 1 best meets the requirements for mirrored storage utilizing two 4TB drives that support one failure.
