I have an Asus N550JK laptop. Currently it has a 240 Intel 530 ssd os drive and a Seagate 2 TB storage hdd. I am toying with putting in a Seagate 1TB hybrid in place of the SSD. or even another 2TB drive with some sort of Ram cache. I have 16 GB of ram. I would love 3 or even 4TB in my laptop. I don't however want to give up all my speed, That is why I am considering a Seagate SSHD.or some sort of Hdd caching software. I have a crap load of games, movies and other stuff not including what I have on external HDD. Thoughts on how to approach this?
