Can a SATA 1.5Gb/s ODD be connected to a SATA 3.0Gb/s port?

I got this Samsung Optical Drive: http://www.newegg.com/Product/Product.aspx?Item=N82E16827151266
I read the specs and found out that it has only "Burst Transfer Rate: 1.5 Gbps SATA".

HOWEVER, my MOBO - ASrock B75M-DGS: http://www.asrock.com/mb/Intel/B75M-DGS/?cat=Specifications has only 1 SATA 6.0Gb/s and 3 SATA 3.0Gb/s ports!(The SATA 6.0Gb/s port has been used up by the HDD)

So my question is, am I able to connect the ODD to one of the SATA 3.0Gb/s port and still make the ODD work without damaging it? (Is it FORWARD Compatible? If there is such a thing.)

    Don't think of your drive as being "Forward" compatible, think of your SATA 3Gb/s port as being "Backward" compatible. And the answer is yes, they are compatible. You just wouldn't be using up the full possible bandwidth of the SATA 3G/s port.

    I read something from this website: http://kb.sandisk.com/app/answers/detail/a_id/8142 that states, "SATA II specifications provide backward compatibility to function on SATA I ports...However, the maximum speed of the drive will be slower due to the lower speed limitations of the port."

    I think the thing you missed out on is that my Optical Drive has a spec of SATA 1. My Motherboard has three SATA 2 ports. It isn't the other way around. My Optical Drive isn't SATA 2 and my Motherboard doesn't have SATA 1 ports.

    Or what you are trying to saying is, these two things are Vice-Versa? Which in my case, the SATA 1 Optical Drive can be connected to one of the SATA 2 port?
  3. Yup, Your Drive is SATA 1 and Mobo is SATA 2. They are compatible. As long as the Mobo has the same or higher spec then then thing you are plugging in, then it should be compatible when it comes to SATA devices.
