Serial ATA (SATA) is a computer bus interface that connects host bus adapters to mass storage devices such as hard disk drives, optical drives, and solid-state drives.

If you plug a SATA 3.0 drive into a SATA 1.5 port on your motherboard, the drive should be able to function at a 1.5Gb/s transfer rate. Some drives require a jumper setting, while others natively recognize their allocated bandwidth and adjust accordingly.
Yes, SATA II (SATA 3 Gb/s) devices are backward compatible with SATA I (SATA 1.5 Gb/s) interfaces. This means that you can connect a SATA II hard drive or SSD to a SATA I motherboard, but the drive will operate at the lower SATA I speed. However, if you connect a SATA I drive to a SATA II interface, it will run at the SATA I speed as well.
It wouldn't be a SATA motherboard if you couldn't connect SATA drives to it.
The Sata II is has a transfer speed that is two times as fast as the original Sata. The Sata has a communication speed of 1.5 Gbit/s while the Sata II is 3.0 Gbit/s.
Serial port generally refers to Serial ATA port. These Serial ATA ports are better known as "SATA" ports. You will find them on Hard Drives and Solid State Drives specifically. But you may also find them on peripherals such as card readers for Flash media and Optical Drives. SATA is categorized into 3 categories SATA, SATA II and SATA III. The Function of SATA is to transfer data. Previous to SATA, Computers used "IDE" service which was far slower and more expensive to manufacture than SATA.
SATA 3 is backwards compatible, it means you connect it the same way as SATA 1.
Ø SATA I- 1.5 Gb/sec, SATA II- 3 Gb/sec and SATA III- 6 Gb/sec
Its faster
Ø SATA I- 1.5 Gb/sec, SATA II- 3 Gb/sec and SATA III- 6 Gb/sec
Speed of sata 1 is 1.5 Gbps Speed of sata 2 is 3 Gbps
