Episode 20 — Understand RAID Levels Removable Storage and Optical Media Tradeoffs
This episode introduces the storage choices that technicians must understand when balancing speed, redundancy, convenience, and risk. For the A+ exam, you should know the basic purpose of common RAID levels, the strengths and weaknesses of removable flash media, and where optical media still appears despite being less common in many environments. The episode explains how RAID can support fault tolerance, performance, or both depending on the level selected, while also making clear that RAID is not the same thing as a backup. It also covers practical issues such as removable media portability, formatting compatibility, wear, and data exposure, along with the limited but still relevant uses of CDs, DVDs, and similar media for distribution, recovery, or archival tasks. By framing these options as decisions with consequences rather than terms to memorize, the episode helps you think like a technician instead of a flash card.
