I will be honest and say I have no experience with Drive Scope on a Fusion Drive, but the NVMe report is essentially the extended S.M.A.R.T. report but gives no indication of the acceptable/expected range. It does NOT offer a surface scan function for the HD portion of the Fusion drive, which is by far the largest component. Unfortunately S.M.A.R.T is quite good at detecting failures, but Surface Scans are superior at PREDICTING failures on rotating rust media. That is specifically why I have stuck with TTP instead of DiskWarrior albeit DiskWarrior probably has the edge in performing volume repairs.


If we knew what it was we were doing, it wouldn't be called research, would it?
