Which of the following are advantages of using Solid State Drives (SSDs) rather than Hard Disk Drives (HDDs) in laptop computers?
- An SSD is much lighter than an HDD
- An SSD has lower power consumption than an HDD
- SSDs are thick compared to HDDs due to no moving parts
A1 & 2 only ✓ Correct
B1 & 3 only
C2 & 3 only
D1, 2 & 3
Correct answer: (A) 1 & 2 only — The advantages are that an SSD is lighter and uses less power, so the answer is 1 and 2.
Explanation
★The advantages are that an SSD is lighter and uses less power, so the answer is 1 and 2.
★A solid state drive has no moving parts and stores data on flash memory.
★This makes it much lighter than a hard disk drive, matching item 1.
★It also draws less power than a hard disk drive, matching item 2.
★Having no moving parts makes SSDs thinner, not thicker, so the third statement is wrong.
★So being thick is not an advantage of an SSD.
★So the advantages are items 1 and 2.
