Why is data access time generally lower in a solid-state drive (SSD) than in a traditional hard disk drive?

Correct answer: Electronic memory does not have to wait for a mechanical head to move

An SSD uses flash memory and electronic control to access data, so it does not need to wait for a spinning disk or a mechanical read/write head to move into position. This generally gives it lower access latency than a traditional hard disk, making option A correct. An SSD is not RAM and requires power to operate.
