Hello, I am pretty sure my hard drive is done for. I have everything backed up on Time Machine to an external hard drive. Ideally I would like to upgrade to a 1TB SSD drive and restore everything from TM which was running El Capitan. I am planning to do this upgrade on my own. Does everything I just described above sound feasible? Can someone help me find the appropriate SSD drive to buy that is compatible? Below is the info for my Mac.
