Question

The type of hard drive that has no moving part, so they are more efficient, run with no noise, emit little heat, and require little power

a) HDD
b) SSD
c) External hard drive
d) USB drive

Answer 1

An SSD, or Solid State Drive, is the type of hard drive without moving parts that's known for efficiency and low power consumption, unlike traditional HDDs that use spinning disks and magnetoresistance for data storage.

Step-by-step explanation:

The type of hard drive that has no moving parts and is known for its efficiency, lack of noise, minimal heat emission, and low power requirement is the SSD, which stands for Solid State Drive. Unlike the traditional HDD (Hard Disk Drive), which uses magnetic encoding and spinning disks to read and write data, SSDs use flash memory to store data. This technology is similar to what's used in USB drives but optimized for more efficient and reliable storage solutions suitable for both internal and external applications.

Historically, HDDs operated on the principle of magnetoresistive induction, where data are written to and read from a spinning disk. Modern HDDs, including external hard drives, use giant magnetoresistance, a result of nanotechnology, to read data. SSDs, not requiring these mechanisms, have no mechanical parts, which contributes to their distinct advantages over HDDs.
