Types of Storage Devices

-Hard Disk Drives (HDDs)

-Solid-state drives (SSDs)

HDDs

Hard Disk Drives

Hard Disk Drives

Store data on magnetic platters that spin at a high speed. A read/write head moves across the platters to access data. Relatively inexpensive and offer large storage capacities, but they are slower than SSDs.

SSDs

Solid-State Drives

SSDs

Store data on flash memory chips. They have no moving parts, making them much faster, more durable, and more energy-efficient than HDDs. Typically more expensive than HDDs for the same storage capacity.

SSDs

Commonly used for storing the operating system, applications, and frequently accessed files.

SSDs

A video editor working with large video files would benefit greatly from using this, as it can significantly reduce the time it takes to load and save files.

NVMe

Non-Volatile Memory Express

NVMe SSDs

Type of SSD that connects to the computer via the PCIe bus, offering even faster speeds than traditional SATA SSDs.

NVMe SSDs

Commonly used in high-performance computers and laptops.

Storage Capacity

The amount of data that a storage device can store, measured in gigabytes (GB) or terabytes (TB).

Seagate Barracuda and Western Digital Blue

Popular HDDs for desktop computers

Samsung 990 Pro

A high-performance NVMe SSD.

Crucial MX500

A popular SATA SSD
