What component do solid-state drives not use, resulting in energy not wasted as heat?

• A. Resistors
• B. Transistors
• C. Diodes
• D. Capacitors

Answer: (A)

Power loss in circuits mainly comes from resistive elements turning part of the current into heat. Solid-state drives store data using transistor-based memory cells (floating-gate transistors) rather than resistive paths. Because the memory elements are not relying on resistors to hold or move charge, there isn’t a significant resistive path dissipating energy as heat in the storage section. Diodes and capacitors appear in SSDs for other functions (like isolation or charge pumping), but they don’t define the energy loss in the way a resistor in a load path would. So the absence of resistive dissipation in the memory path means energy isn’t wasted as heat in the way it would be if resistors were used for storage.
