Chosen Solution

Hi all, thank you first for reading and maybe replying my answer (wtf my english, sorry). I know i could search on the web, but on it i couldn’t find all I needed. I’m here because I need to replace my HDD with an SSD. I didn’t understand 3 thing:

  1. I have a SATA 2 on my iMac and the SSD is SATA 3. Ofc I’ll lose performance, so… Can I do something to resolve that? (Change my iMac SATA maybe?)
  2. My iMac will not be filled up, so I can put my SSD as first and only HD. Is that ok? Can I do that? (Or it’s better to put it together my default HHD [it’s called fusion drive right?])
  3. I read that to put my SSD I need at all cost to remove my SuperDrive (CD and DVD drive) and then but a support, is that right? I know, a lot of answer, but I say thank you a lot if u can reply completely. Ty for your time and patience again. BB - Alberto

You can not change the SATA speed on your machine - it’s a function of the bus. Some sATA III drives play quite well at lower speed (they are “self-limiting” and virtually transparent to the user) others have to be manually set to lower speed (do some research - see links below). As for your proposal see this and this previous answers to the same question. If this answer is acceptable please remember to return and mark it.
