I am considering getting a refurbished 2010 iMac to save some money and plan to put an SSD in it. To my knowledge, the 2010 iMacs only had SATA II, and thus, are not able to run at 6Gb/s like a lot of these new SATA III SSDs are capable of. I'm very uninformed about this topic and couldn't find the answer I wanted via search. So my question is, how much does this limit performance? Would an OWC 6G SSD simply saturate the entire 3Gb/s on SATA II? Would that be my bottleneck? Or are the performance gains by SATA III SSDs simply insignificant at this moment? Are these SATA III SSDs actually using that 6Gb/s? Thanks in advance.
