What is SATA (Serial Advanced Technology Attachment)?

This content has been automatically translated from Ukrainian.
SATA (Serial Advanced Technology Attachment) mode is one of the operating modes for connecting devices to a computer via the SATA interface. SATA is a standard for data transfer between a hard disk drive (HDD) array or solid-state drive (SSD) devices and the computer's motherboard.
SATA uses serial data transmission, allowing information to be sent one bit at a time. The SATA operating mode determines the data transfer speed and capabilities of the connected device.
The most common SATA modes include:
  1. SATA 1.5 Gbps: This is the first version of SATA, which transfers data at a speed of 1.5 gigabits per second (Gbps). It was introduced in 2003.
  2. SATA 3 Gbps: This version of SATA transfers data at a speed of 3 gigabits per second (Gbps) and was released in 2004. It is popular among older computers and devices.
  3. SATA 6 Gbps: This is the most common SATA mode, which supports a data transfer speed of 6 gigabits per second (Gbps). It was introduced in 2009 and provides fast data transfer for modern HDDs and SSDs.
The SATA mode can be configured in BIOS or UEFI on the computer's motherboard. Depending on the connected device and motherboard support, you can select the appropriate SATA mode to ensure optimal data transfer speed between devices and the computer.
