I am planning on purchasing some extra storage space. Another WD Velocirapor HDD 1TB to match the one I have, and two Samsung 840 EVO 1TB SSD's and I am wondering what would be one of the best or at least more preferred raid configurations I can use. I am new to raid but want to expand the space, stability, and speed of my system storage. Can anyone give me some tips, pointers and possibly direct me to some good guides?
