Hey everyone, I could use some advice. I own a late 2011 15 inch macbook pro. I previously swapped out the harddrive for a 512 ssd. I am currently looking at swapping out the optical drive for a hdd, and am confident that I can do it. My question though is what is the maximum size hdd that I could fit into the bay (and i mean gb size not physical size). The problem that I am having is that my photo library has grown far to large to store in my current ssd, but I would like to have it hand at all times. With this said, would there be any benefit to getting a fusion drive? I assume I am better off with a hdd rather than a ssd simply because it will provide more space for library. Any help would be appreciated.
