What is the speed of SATA 3?

1.5Gbps or 150MBps
3Gbps or 300MBps
6Gbps or 600MBps
16Gbps or 1969MBps

The correct answer is: 6Gbps or 600MBps

The speed of SATA 3 is indeed 6Gbps or 600MBps. This specification, also known as SATA III, is twice the speed of its predecessor, SATA II, which has a maximum transfer rate of 3Gbps. The increased speed allows for faster data transfer between the storage devices, such as solid-state drives (SSDs) and hard disk drives (HDDs), and the motherboard, improving overall system performance. The data transfer rates you see in the other options do not correspond to SATA 3. For example, 1.5Gbps or 150MBps is associated with SATA I, while 3Gbps or 300MBps refers to SATA II. The high speed of 16Gbps or 1969MBps is irrelevant as it pertains to other technologies like SAS (Serial Attached SCSI) or comparable interfaces but not SATA standards.
