# Should I buy an external SSD or a hard drive (HDD)?

It depends on the job:

- **SSD** — much faster, silent, more robust when carried around. Best for anything you open or work from: apps, libraries, projects.
- **Hard drive (HDD)** — cheaper per terabyte but slower, especially with many small files. Fine for Time Machine backups and archives you rarely open.

Many people use both: an SSD for working data and a larger HDD for backups.
