RAID-10: The Optimal Solution for Mission Critical Applications

Which Redundant Array of Independent Disks (RAID) combines mirroring and striping and is the better option for mission critical applications?

A. RAID-10

B. RAID-5

C. RAID-1

D. RAID-0

Answer: RAID-10

The Redundant Array of Independent Disks (RAID) that combines mirroring and striping and is the better option for mission critical applications is:

RAID-10

RAID-10 stands out as the superior choice for mission-critical applications due to its unique combination of mirroring and striping. This RAID level mirrors data to two or more disks while simultaneously striping it across multiple disks. This dual approach allows for enhanced performance since data can be read from multiple disks in parallel.

Moreover, RAID-10 offers a critical advantage in terms of data redundancy. In the event of a single disk failure, data remains intact as it can be reconstructed from the mirrored disks. This high level of fault tolerance is crucial for applications where downtime and data loss are unacceptable.

While RAID-5 also provides some data redundancy through parity and increased performance, it falls short of RAID-10's reliability in the face of multiple drive failures. RAID-1, which offers data redundancy but lacks performance improvements, and RAID-0, which boosts performance but sacrifices data redundancy, are not as well-suited for mission-critical environments.

It is important to note that RAID-10 may come at a higher cost compared to other RAID configurations due to the need for multiple disks. However, the unmatched reliability and performance it offers make it an excellent choice for safeguarding critical data and ensuring uninterrupted operations.
