SATA, or Serial AT Attachment, is a computer interface that connects storage devices like hard drives (HDDs) and solid-state drives (SSDs) to a computer's motherboard. It uses a serial cable for data transfer, offering faster speeds than older Parallel ATA (PATA) connections and a more streamlined, smaller cable. SATA is the standard for desktop and laptop storage, providing the connection for traditional 2.5-inch and 3.5-inch drives as well as specialized versions like Slimline SATA for smaller devices.

Key Characteristics:

Serial vs. Parallel: SATA uses serial communication, meaning data is sent one bit at a time, whereas PATA sent data in parallel. This allows for higher speeds and simpler, thinner cables.

Device Compatibility: SATA is the primary interface for internal storage devices, including:

HDDs: Traditional spinning hard drives, available in 2.5-inch and 3.5-inch form factors.

SSDs: Solid-state drives that are much faster than HDDs.

Optical Drives: Such as DVD and Blu-ray drives.
