I searched the boards but couldn’t find anybody with the same query.
My Drobo has 2 WD 500g and 2 WD 1tera drives in it. Drobo seems to always be working, always sounds like the drives are being written to, sounds like the heads are in constant motion.
I don’t remember this being the case when I just got it, although that has been a year or so ago. Is this normal or am I being paranoid?
