I just replaced my Internal HDD with my SSD boot drive. and I think given how easy it was I'm happy to go ahead and install a second drive.. but as I'm going into the whole thing, I want to install a 1/1.5TB drive. Can anyone recommend a reliable 1/1.5TB drive? is Sata III 5400rpm the best the mac mini (2012) will accept? Alsao is the max depth a 7mm drive? I haven't seen any 1.5TB 7mm drives around?
