Which is NOT descriptive of a solid state drive? Energy efficient Contains many moving parts More expensive storage than mechanical drives Nonvolatile storage
The Correct Answer and Explanation is:
Correct Answer: Contains many moving parts
Explanation:
A solid-state drive (SSD) is a type of data storage device that uses flash memory to store data, offering significant advantages over traditional hard disk drives (HDDs). One of the defining characteristics of an SSD is the absence of moving parts. Unlike mechanical drives that rely on spinning magnetic disks and read/write heads, SSDs use integrated circuits and flash memory to store data electronically.
Because there are no mechanical components in SSDs, they are more resistant to physical shock, run silently, and operate at faster speeds. This also makes SSDs more energy-efficient, as they require less power to operate compared to traditional HDDs. This quality is especially valuable in mobile devices and laptops, where battery life is important.
SSDs are also considered nonvolatile storage, meaning they retain data even when the power is turned off. This makes them suitable for long-term data storage and a reliable alternative to volatile memory types like RAM, which lose their contents when the system shuts down.
While SSDs offer many advantages, one trade-off has historically been their cost. SSDs are more expensive per gigabyte than mechanical HDDs. However, as technology advances, the price gap has been narrowing.
In summary, the only statement that is not descriptive of a solid-state drive is that it “contains many moving parts.” This characteristic applies to traditional hard disk drives but not to SSDs, which are built with solid-state electronics and lack the mechanical components of older storage technologies.
