A few months back I replaced the hdd in my 2011 MacBook pro with a 128 gb ssd. I've always meant to swap the optical bay with the original hdd but haven't got around to it. Now that I could use the space I've been doing some reading. I just have a few quick question to clear up, due to some conflicting information I have found. First: http://www.ebay.com/itm/2nd-HDD-SDD...C_Drives_Storage_Internal&hash=item415b737383 this is the correct product for my particular computer correct, I have seen this seller recommended many times on here. My other question is, and I've heard different answers. Should the ssd go where the optical bay was, or in the hdd bay? I have heard that since I have my os on the ssd, putting it in the optibay may cause some sleep/wake issues? Will there be any issue with heat having a regular hdd in the optical slot, since it was obviously not designed for this? Those are my only remains questions. If you have any other advice I would love to hear it.
