A hard disk drive (HDD), hard disk, hard drive, or fixed disk[b] is an electro-mechanical data storage device that uses magnetic storage to store and retrieve digital information using one or more rigid rapidly rotating disks (platters) coated with magnetic material.
Activities
- Learn about SDD storage technology and compare it with HDD technology
- Use
lsblkandblkidcommands in Linux to identify your HDD devices - Use iotop, iostat and sar -d in Linux to assess you disk usage
