I use SSDs for Windows, documents, and 'in process' photos. Everything else goes to a 3tb HD that is in a slide in/out bay as is another 3tb HD that slides in/out another bay. The 2nd HD gets mounted and everything copied to it, then #1 removed and saved in a cabinet. For offsite backup, I use an eSATA 3tb HD that is stored about 2 miles away. Worst case scenario, I lose about 30-60 days email history.
