I currently have a 1Tb Ensemble and wanted to add a 2Tb drive to it. I figured if I purchased 2x2Tb drives (NON-ent), I could put one in Ensemble and keep full backup offline. Say something like Seagate that offers 5 yr warranty. One goes down, I replace with backup (obviously backup again to another drive at that time) and send damaged drive out for replacement. My point in the this post/thread was to know IF a NON-ENTERPRISE drive offered ANY drop in performance (or ANY other issue) other then dependability/reliability issues.

861v4, DSP6000 (24/96), DSP5000C (24/96), Ensemble (1TB)
