I want to add an SSD and a 2TB HDD to my current system which has already got a 2TB HDD. I want to do this as the system is very slow and I want to speed it up. The problem is how do I go about this, do I get rid of my current HDD and replace it with the new or just keep it with the two other storage devices. I also want to know how to install the OS onto the SSD and not onto the other HDDs. Thanks!
