Drivepool has automatically and without SMART features enabled, detected a failing drive and auto migrated all data to a good drive just before it failed. I only lost 1GB (6 files) from the failing 4TB drive that was around 90% full. These files are one of a kind and nearly impossible to recover if lost and I don't use duplication because i have over a petabyte of data stored and no room for it. Drivepool is by far the best piece of software I've ever purchased.
