Exam Tips - Secondary Storage
Most common exam questions:
- "Name three types of secondary storage" → HDD (magnetic), SSD (solid state), Optical (CD/DVD/Blu-ray)
- "Which is fastest?" → SSD (no moving parts, flash memory)
- "Which is cheapest per GB?" → HDD (magnetic)
- "Which is most durable?" → SSD (no moving parts, shock-resistant)
- "Which is best for portability?" → Optical (lightweight, no power needed) or SSD (durable, lightweight)
Key comparison phrases:
- Speed: "SSD is fastest, HDD is moderate, Optical is slowest"
- Cost: "HDD is cheapest per GB, SSD is most expensive"
- Capacity: "HDD has highest capacity, Optical has lowest"
- Durability: "SSD is most durable (no moving parts), HDD is fragile (moving parts)"
Scenario questions - How to choose:
- Video editing: SSD (needs fast read/write for large files)
- Budget laptop: Small SSD + cloud storage (balance speed and cost)
- Photo archive (10,000 photos): HDD (cheap, high capacity)
- Software distribution: Optical (portable, cheap to manufacture many copies)
- Gaming PC: SSD for games, HDD for storage
Common mistakes to avoid:
- Confusing RAM with secondary storage - RAM is volatile, secondary storage is permanent
- Saying HDD is faster than SSD - NO! SSD is always faster
- Forgetting to explain WHY in scenario questions - always justify your choice
- Not mentioning "no moving parts" for SSD durability - this is the KEY reason
