How does an SSD work?
A solid-state drive (SSD) stores data in flash memory chips with no moving parts. Instead of spinning disks, it saves information as electrical charges in tiny cells — making it far faster, quieter, and more durable than a traditional hard drive.

Frequently asked questions
- How does an SSD work?
- It stores data as electrical charges in flash memory chips, with no moving parts, for fast access.
- Why are SSDs faster than hard drives?
- They have no spinning disks or moving heads, so they can access any data almost instantly.
- Do SSDs wear out?
- Memory cells have a limited number of writes, but modern SSDs last many years under normal use.
