## Definition

Stands for solid state drive. A type of storage device for computers that is much faster than an old-fashioned hard drive. It has no moving parts, so it is quieter and less likely to break if you drop it.

For teachers: Abbreviation for solid state drive. A data storage device that uses integrated circuit assemblies to store data persistently, typically using flash memory. It contains no moving mechanical components, distinguishing it from traditional hard disk drives.

## Examples

- I upgraded my laptop with an SSD to make it faster.
- Installing an SSD is the most effective way to reduce the time it takes for your computer to start up.
- While traditional hard drives rely on spinning platters and magnetic heads, an SSD accesses data electronically, resulting in significantly lower latency and higher throughput for demanding applications.

## Usage notes

- Often used as an initialism for 'solid-state drive'; functions as a countable noun in technical and consumer contexts.
