SSDs (Solid-State Drives) and HDDs (Hard Disk Drives) are both data storage devices, but SSDs are significantly faster, more durable, and energy-efficient, while HDDs offer higher capacity at a lower cost. SSDs use flash memory with no moving parts, making them ideal for OS and app performance, whereas HDDs use spinning magnetic disks, suited for mass, long-term storage.
