I have a 1TB WD Green, two 1TB Seagates (model unknown) and a 1.5TB Seagate in my Drobo V1. I’m getting another 1.5TB today (a WD Green “4k sector” WD15EARS). The WD 1TB is the oldest by about 6 to 9 months I would guess.
The question is: is there any way from the current logs to decide which of the three 1TB drives I should replace? Any clues in there as to error rates or other indicators?
