Hello all i have a 240gb ssd on its way along with a optical drive caddy. i have a early 2011 macbook pro 15". i know the main drive bay is the sata 3 and the optical still uses sata 2 so im installing the ssd in the main area and the platter drive in the optical. on to my question. im wondering if using the ssd and the hdd separate and managing the data myself is better than fusion. now it i did go this route can the documents and downloads folder be relocated to the hdd like how you can under windows? main reason is i have read that fusion will write and fill the ssd then as it gets full it will start using the hdd. is this correct? i was hoping it would have the os on the ssd and then write everything to the hdd then only what you use frequently gets wrote to the ssd. i have several macs but this is the first i will be having an ssd in mainly because im spoiled by my gaming desktop and miss the speed. haha thanks for your time.
