I don't understand it yet, need help with HDD configuration

Hey guys

I just installed Fedora 21 and I'm trying really hard to create a virtual machine with vga passthrough. Anyway I used my arc 100 120GB for some scratches and tests, the last time I installed it I decided to use the same SSD and a 320GB WD BLUE. I choosed the easy partition method and than I selected both the drives during the installation. Now I don't know how to distinguish what is on which drive and how to install a program on the SSD or on the HDD.

Please help me. I really like using linux, expecially gnome that has a wonderfull interface, but sometimes I get confused

wait wut?

You tried to install fedora 21 on two separate hard drives? Just reinstall on your SSD. Use your 320GB HDD as a plain old data drive.

Ok, but how can you install a programm on the second HDD?? And there is a way to mount the second HDD automatically when you boot??

The best way would be to setup the system as normal. However set the home directory to mount on the second drive.

This will mean the OS and everything requiring speed shall be on the SSD and all user data on the HDD.
