Storage devices in a computer are hardware components that are used to store and retrieve data. These devices can be internal or external and come in various forms such as hard disk drives (HDD), solid-state drives (SSD), USB flash drives, memory cards, and optical discs (CDs, DVDs). They are essential for saving files, programs, and operating systems on a computer for later use.

Primary Storage (Volatile):
- RAM (Random Access Memory): Stores temporary data and instructions accessed by the CPU directly.
Secondary Storage (Non-Volatile):
Solid State Drives (SSDs):
- SATA SSD: Connects via SATA interface, offering high read/write speeds.
- NVMe SSD: Uses PCIe interface, providing even faster speeds than SATA.
Hard Disk Drives (HDDs):
- Mechanical HDD: Uses spinning magnetic disks to store data, offering large capacities but slower speeds.
Other Secondary Storage:
- Optical Drives (CD/DVD/Blu-ray): Reads and writes data on optical discs.
- Flash Drives: Portable, removable storage devices that use USB or other interfaces.
- Network-Attached Storage (NAS): Centralized file storage accessible over a network.
- Cloud Storage: Remote storage services accessible via the internet.
Specialized Storage Devices:
- SAN (Storage Area Network): High-speed network for connecting multiple storage devices to servers.
- Tape Drives: Used for archiving and backup purposes, offering high capacity but slow read/write speeds.
- Removable Storage Cartridges: Used for enhanced portability and security in specific environments.
- RAM (Random Access Memory): Stores temporary data and instructions accessed by the CPU directly.
