Hi guys, I would like to install an SSD in my GF's iMac (in the optical bay). This would I hope enable me to make a fusion drive with the existing HDD that is already in there. Does anyone have any experience of doing this on this exact model (see title). Specific things I would like to know are: Does it need 3g or 6g SSD? Is this the Sata speed that can be checked in system info? What are negotiated link speeds and are they important and dependant on the drive used? Do i need TRIM? Do I need to short the fans out are some are suggesting or is that only if you are replacing the original HDD? Do I need any special leads? I think I may need mini-sata to sata? What mounting case are you guys buying to hold the SSD in place in the optical bay? Specifically, if anyone from the UK has done this I would be very interested as the only company I can only find that supplies the mounting is OWC in the States. I have spent 2 hours reading through threads on various websites, but am nervous about getting it exactly right and of course, most people's thread are relating to different imacs. Many thanks guys. hardtofin EDIT: Would something like this do the job http://www.dabs.com/products/kingst...-drives-75K4.html?q=2.5 to 3.5 adapter&src=16 or do SSD's not have the mounting holes in the same place (note this is a kingston converter).
