It's a non-issue. Why? Because if SATA 3 devices only worked on SATA 3 controllers then they would die an early death because few could use them. I hope your vendor/maker/support was clear about this.
However there are plenty of SSD issues besides this non-issue. Be sure your supplier notes your laptop compatibility.
I think Jimmy Greystone will know a lot about this topic, but all answers welcome
I am thinking of upgrading a 13inch Macbook Pro Mid2010 with an SSD. I think it only supports SATA 2 and not SATA 3.
Can you please assist as to how to check SSD compatibility?
Do all SSDS work with my mac so long as they are 2.5inch drives?
What else do I have to consider in regards to compatibility besides SATA 2 or 3 support?
Thanks in advance
