my iMac doesn't have Sata3 ports?

[zoran]

Recently i decided to install an SSD drive in my mid 2010 core i7 2.93GHZ 27" iMac but i found out very sadly that my imac doesn't have SATA3 ports, only SATA2, is this true?
Also, is it known how many SATA ports my model has?

That's correct. It was 2011 that it jumped to sata 3

So now will i be experiencing difference in speed if i were to own an iMac with a sata3 port? Im gonna be using graphic design apps (Adobe CS6).

Sata 3 is half the speed of sata 6 but you'll see a jump changing a platter drive to ssd due to the throughput increase.

You'll see about 300-350mbs compared to 5-550ish depending on drive

On SATA 2 there will be a noticeable difference in speed as the SSD will be able to saturate it. Compare that to the HDD in my 2010 iMac which hovers around 90 MB/s both read and write and is clearly the reason it's so slow on Yosemite.
