I have two 3TB WD30EFRX-68AX9N080 drives in a QNap NAS. They are set up in a mirrored configuration. They are quite old, and my storage is operational 24/7, primarily for local home use, storing music, videos, and photos.
It would be disastrous if I were to lose the information on them.
I want to be foresighted about potential issues. Besides the SMART check, what else would you recommend?
You have nothing to worry when there is a RAID-1 array, especially regarding HDD failure event.
But in both cases, NAS or PC RAID Array, you need to do some homework about how to replace a damaged drive by your self.
Or, and this is the best advice, leave a computers repairs specialist Pro, him to do the work.
We all count at SMART information so this to alert us about HDD health status.
Before SMART, Industry was using a crystal ball to determine data storage media surface health, but these media were named as 1.4 MB Floppy.
