Hi all, I've spent a good few hours trawling the web for info about adding an SSD to my mac using an optical bay caddy. I currently plan on buying a samsung 840 series 256Gb for £119, using it in the HDD bay and moving my existing HDD to the optical bay. My problem is that I can't seem to find (looked through Amazon & Ebay) an optical drive caddy that matches the model number for my MBP (which I believe is MC723xxx). There are loads that work for the models up to 2011 but they don't specifically list my model. Can anyone direct me towards a good value caddy available in the uk that they have used successfully that would fit my MBP as well? I am also open to a bundle that would include an external caddy for my optical drive. Thanks in advance for any help.
