What is the speed of SATA 1?

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

The correct answer is: 1.5Gbps or 150MBps

The speed of SATA 1, also known as SATA I, is indeed 1.5Gbps, which translates to 150MBps. This specification was introduced as the first version of the Serial ATA interface, aiming to improve data transfer speeds compared to the older Parallel ATA (PATA) technology. SATA I's 1.5Gbps speed represents the theoretical maximum bandwidth, meaning that the actual data transfers may be lower due to protocol overhead and other factors. The subsequent versions of SATA, including SATA II and SATA III, significantly increased these speeds to 3Gbps (300MBps) and 6Gbps (600MBps), respectively. The option that mentions 16Gbps is related to a different standard (SAS - Serial Attached SCSI) and not SATA, making it irrelevant in this context. Understanding these specifications is crucial for recognizing how different generations of SATA interfaces have evolved to meet increasing performance demands.
