Tried googling for “WD MTBF replacement drives” to find no info on this aspect. The drives I get back from Thailand always have a ‘white’ sticker, not the same red/white (at least for the Red and Red Pro NAS drives) sticker that comes on their retail drives.
I’m assuming these are simply refurbished drives, and I do recall previously that one of these warranty replacement drives died much sooner than a typical retail drive in one of my Synology boxes.
So my concern is if/when I throw in a warranty replacement if/when my ZFS (FreeNAS) array needs re-silvering that it may die during the resilvering process and potentially a lot worse on the Synology RAID boxes as they are older…?
There doesn’t seem to be much info in terms of MTBF on these warranty replacement drives or their performance standards.
