Week 3: Storage, SATA, NVMe, SAS, M.2, and RAID
210 instructional minutes | five 42-minute lessons
This week compares storage by workload, interface, form factor, performance, durability, redundancy, and failure evidence rather than capacity alone.
Lesson sequence
- Storage Is More Than Capacity
- SATA, NVMe, SAS, M.2, and mSATA
- RAID Is Not Backup
- Storage Selection Lab
- Diagnose the Missing or Failing Drive
Evidence you will produce
- storage technology/workload comparison;
- interface and protocol map;
- RAID decision with backup distinction;
- storage-selection rationale;
- failure ticket using firmware, controller, OS, filesystem, SMART, and symptom evidence.
A+ alignment
Primary coverage: Core 1 objectives 3.4 and 5.2.
Safety boundary
Preserve data before destructive changes. Do not initialize, format, rebuild, or replace storage until the evidence and recovery requirement justify the action.
