Solid-state storage is defined by having no moving parts. It stores data in memory chips, like flash memory, which is non-volatile and retains data without power. Because there are no spinning disks or mechanical read/write heads, access is much faster, it’s quieter, uses less power, and is more resistant to physical shocks. In contrast, devices with spinning platters or magnetic tape rely on moving components, which is why they’re slower or used in different scenarios (like archival storage). Thus, the key feature is the absence of moving parts.
