What is the speed of SATA 2?

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

The correct answer is: 3Gbps or 300MBps

SATA 2 (Serial ATA 2) has a maximum speed of 3Gbps or 300MBps. This is because SATA 2 uses a 3Gb/s signaling rate, which translates to 300MB/s transfer rate. The other options are not correct because they do not match the signaling rate used by SATA 2. Option A refers to SATA 1, which has a signaling rate of 1.5Gb/s. Option C refers to SATA 3, which has a signaling rate of 6Gb/s. Option D is incorrect as SATA 2 does not have a signaling rate of 16Gb/s.
