For storage I'm using a drobo s with 5 3TB 7200RPM drives setup as RAID 5. I will be adding a second identical unit next week to mirror the first one for backup purpose. Be advised that RAID 5 provides data redundancy and is not a backup device alone. That is why I will be adding a 2nd unit next week for backup. Not cheap but I do NOT want to rip all my movies again if my storage device crashes, not fun.
Once I add my 2nd RAID I will post pictures.
