Hi everyone, The HDD on my 2009 iMac 27" i7 2.8 GHz recently died and so I was looking to upgrade to a Fusion Drive with a Samsung 840 250GB SSD and a 2 TB HDD. I have searched quite a bit regarding replacing the optical drive and came across a variety of issues people had when doing so. So, for people with experience doing this.. I realize my iMac is a SATA II and will not get the actual 6GB/S of most SSDs, but is the boost really worth the $$? Also, I am curious on how to best install the HDDs. I had planned to do the easy and cheapest way of installing the SSD in the optical drive bay and a 3.5" HDD in the main bay, but I have read where some people claimed they had terrible performance from putting the SSD in the optical bay and were getting sub-SATA I speeds. I am not sure why this would be the case, but nobody had a good explanation. Can anyone vouch for this setup or have any ideas about the optimum way of installing? Any other advice you would have about the process? Thanks in advance!
