Which statement lists the two performance advantages of solid-state drives over hard disk drives?

• A. No rotational latency; no seek time
• B. Faster boot times; larger capacity
• C. Lower power consumption; reduced heat
• D. More moving parts; cheaper cost

Answer: (A)

Solid-state drives use flash memory with no moving parts. The two clear performance advantages come from that: there is no rotational latency because nothing has to spin up to bring data under a sensor, and no seek time because there’s no actuator head that must move to the correct location. With those delays eliminated, access is much faster and random I/O performance is greatly improved, which shows up as quicker boot times and snappier application loading. Other benefits like lower power or heat are real, but the direct performance gains asked about here are the absence of rotational latency and seek time.
