What does SSD stand for, and how is it different from HDD?

The term SSD stands for Solid State Drive. This type of storage device differs significantly from a Hard Disk Drive (HDD) in its technology and performance characteristics. SSDs utilize flash memory to store data, which allows for faster read and write access times compared to HDDs that rely on spinning disks and moving read/write heads to access data.

Because SSDs have no moving parts, they generally provide quicker boot times, faster file transfers, and improved overall system responsiveness. This technology also typically results in greater durability and robustness, as SSDs are less susceptible to physical shock compared to the mechanical components in HDDs. Additionally, SSDs consume less power, making them a more energy-efficient option.

In contrast, the other options present definitions or characteristics that do not accurately describe an SSD. For instance, "Sustainable Solid Drive" does not relate to any recognized storage technology, "Static Storage Device" mischaracterizes the speed capabilities of SSDs, and "Super Speed Disk" suggests a need for significantly more power, which is also inaccurate. Thus, recognizing an SSD as a Solid State Drive that uses flash memory underscores its key advantages over traditional HDDs.
