SSD
Definition
A Solid-State Drive (SSD) is a type of non-volatile storage media that stores persistent data on solid-state flash memory. SSDs have no moving mechanical components.
Why It Matters
SSDs are significantly faster than traditional Hard Disk Drives (HDDs). Upgrading from an HDD to an SSD is one of the most effective ways to improve a computer's overall performance, leading to faster boot times, quicker application loading, and more responsive file operations.
Contextual Example
A computer's operating system and frequently used applications are typically installed on an SSD to take advantage of its high speed.
Common Misunderstandings
- Unlike HDDs, SSDs are resistant to physical shock and run silently.
- While more expensive per gigabyte than HDDs, SSD prices have fallen dramatically, making them standard in most new computers.
