6 Storage Engineer Interview Questions and Answers

Introduction

This question assesses your foundational knowledge of storage technologies, which is crucial for a Junior Storage Engineer role.

How to answer

• Define RAID (Redundant Array of Independent Disks) and its purpose in data protection and performance
• Explain at least three different RAID levels (e.g., RAID 0, RAID 1, RAID 5) and their characteristics
• Discuss the trade-offs between performance, redundancy, and storage efficiency for each level
• Mention scenarios where specific RAID levels would be most beneficial
• Show your understanding of how RAID is implemented in storage solutions

What not to say

• Providing vague definitions without clarity on RAID's purpose
• Failing to mention specific RAID levels or their differences
• Overcomplicating explanations without considering the audience's understanding
• Neglecting to connect RAID concepts to practical applications

Example answer

“RAID stands for Redundant Array of Independent Disks, which combines multiple disks into a single unit to improve data redundancy and performance. For example, RAID 0 offers striping for performance but no redundancy, while RAID 1 mirrors data for redundancy at the cost of half the storage capacity. RAID 5 strikes a balance by using parity for fault tolerance and striping for performance, making it suitable for many server environments. Understanding these concepts is key to designing robust storage solutions.”
