Lesson Plan

• Describe the architecture and operation of fixed and portable solid‑state drives.
• Compare key characteristics (capacity, speed, power use, durability, cost) of fixed SSDs, portable SSDs, pen drives and HDDs.
• Evaluate which storage device best fits a given scenario based on capacity, performance, portability and budget.

• Projector and screen for slides
• Laptop with internet access
• Sample fixed SSD, portable SSD, and USB pen drive
• Printed comparison‑chart handout
• Whiteboard and markers
• Quiz worksheets / exit‑ticket cards

Start with a quick poll: “Who used a USB pen drive or external SSD this week?” Capture responses on the board to activate prior knowledge. Briefly outline today’s success criteria – students will be able to describe, compare and choose the appropriate storage device for different tasks.

1. Do‑Now (5') – Students list all storage devices they own and share one advantage of each.
2. Mini‑lecture (10') – Explain SSD technology, differentiating fixed vs. portable SSDs and the role of NAND flash.
3. Interactive comparison (12') – Display the comparison table; students fill a Venn diagram highlighting similarities and differences.
4. Hands‑on demo (10') – Connect a portable SSD and a pen drive to the laptop, demonstrate file‑transfer speeds and discuss interface impact.
5. Guided practice (8') – In pairs, students choose the best device for three real‑world scenarios using a checklist.
6. Check for understanding (5') – Quick Kahoot quiz covering key characteristics and selection criteria.
7. Summary & Q&A (5') – Recap main points and answer lingering questions.

Summarise how SSDs, portable SSDs, and pen drives differ in speed, capacity, durability and cost. Ask students to write one “exit ticket” stating which device they would recommend for a video‑editing project and why. Assign a brief homework: research the price of a 1 TB portable SSD and compare it to a 1 TB HDD.
