What does SSD stand for?

The term SSD stands for Solid State Drive. This designation reflects the type of storage device that utilizes integrated circuit assemblies to store data persistently, typically using NAND-based flash memory. Unlike traditional hard disk drives (HDDs) that rely on moving mechanical parts, SSDs offer faster data access and transfer speeds, greater reliability, and lower power consumption. The "drive" in the name signifies that it functions as a storage solution similar to how traditional drives operate, but with the advantages of solid-state technology.

In digital storage terminology, "drive" is widely accepted in describing devices that store data, making it the appropriate choice in this context. The other options—like Solid State Disk—could have been used to describe the technology historically, but "Solid State Drive" is the current and standard terminology widely adopted in the industry today.
