Storage device

Storage devices allow you to store data for later use. Storage devices can be internal or external. Most storage devices store data

until you manually delete the data. Examples of storage devices are hard‑disk drives (HDD), solid‑state drives (SSD), optical-disc

drives, flash drives, and so on.

Internal storage devices

Internal storage devices are installed on your computer and generally cannot be removed while the computer is turned on. The most

common internal storage devices are hard-disk drives—HDDs and solid-state drives—SSDs. HDDs and SSDs use SATA interface to

transfer information. SSDs are also physically similar to HDDs, which makes them compatible with existing computers. HDDs contain

disk platters. SSDs use flash memory which makes SSDs faster, quieter, energy-efficient, and shock resistant.

Removable storage devices

Storage devices that can be removed from your computer without turning off your computer are called removable storage devices.

Commonly used removable storage devices include:

• Optical discs

• Memory cards

• Flash drives

• External hard drives

Optical drives and discs

Your computer may support a DVD RW or a DVD RW and Blu-ray combo drive. Optical discs can be read-only, write-once, or re-

writeable. Some of the common types of drives are:

• Blu-ray writer—Reads and writes to Blu-ray Discs, DVDs, and CDs.
