So I know a SATA3 handles a maximum speed of about 750MB. But when comparing this HDD and this SSD, what would be the difference in terms of read/write speed. Won't they both be using the SATA3 busing and having a maximum speed of 750MB? If I wanted to choose a drive that gives me the best read/write speed, which one should I go for, or are they both relatively the same?

The SSD is much faster. The HDD has 10000rpm but is still slower.
// Edit. Add content of my comment to the answer:
Because a HDD is limited by it platters and spindle. Moving the head to the right position takes some time. SSDs don't have this. SSD can be read much faster because it doesn't have an mechanic parts. The data are read from Flash modules. Here is a link for you:
Yes, but you are not comparing apples to apples. You are only looking at the BUS and the read/write speed; however, you are not accounting for latencies, which are always much lower in an SSD (basically any SSD on the market for SATA3).
HDD's didn't used to share the read/write often because the bigger issue then was how fast the platters could spin (4800, 5400, 7200, 10000) which was a direct relationship to the latencies and seek times (more-or-less).
Anyway, the Velociraptor typically maxes around 115 in the last tests I saw.
I'd suggest reading the article on Wikipedia about the performace characteristics of hard drives.
