A little bit of story:

I was planning on buying an SSD for my (old) laptop and wanted to know my laptop SATA ports. I plan to replace it with the optical drive using a caddy.

After a bit of research, I got to know that a SATA 3 connection efficiently uses an SSDs' speed. I was wondering what type of port my Optical Drive is connected in.

I referred to this answer, and I know that if a motherboard is SATA 3 based, then every port is SATA 3 (I might be off on the statement).

However, HWiNFO reports something else.

The Hard Drive: enter image description here

The optical Drive: enter image description here

What does this actually mean? Does my motherboard have different SATA connections? Will I be able to replace the Optical Drive with the SSD to avail its benefits?

You're looking at different values and you're comparing the wrong thing.

With the screenshots you're showing you're comparing the "Drive Controller Information" for your DVD drive (which does include the speed) to the "ATA Transport Version Supported". If you take a closer look the "Drive Controller Information" for your HDD/SSD is listed as running at 6 Gbps. Also you can infer that the DVD drive is running at 1.5 Gbps. 1 Gbps should be plenty to read a DVD and different connections for SATA can run at different speeds. It might be that the controller on the DVD drive doesn't support more. Depending on your model you might be unable to use that connection for something else, if you can you could attach a drive to check whenever it also supports 6 Gbps.
