I would like to install Ubuntu 14.04 on my PC, but I'm uncertain on what would be the best for my setup. I have a 128GB SSD (Crucial M4) and two 500GB HDDs.
Currently I'm running Windows 8 where I have Windows installed on my SSD and with the help of Storage Spaces I have an additional 1TB D:/ drive.
I kind of wanted a similar (or maybe a completely different but better) setup for Ubuntu. The system should be installed on the SSD (for performance reasons, obviously) and my Documents, Music, Videos, etc. should be stored on the two HDDs.
I thought about using a software raid, as it is described in this AskUbuntu post, also with level 0 or 1 (I don't mind missing 500GB of storage, I don't need that much). I also heard about LVM, but even after researching for quite some time I don't know if would be useful for me and even if, I'm too insecure to set it up.
Now I wanted to ask you for help. Maybe you have a similar setup or just know what would be the best alternative.
Thanks in advance for your help.
Edit 1: I also have a 500GB external hard drive which I would use for backups.
