I read over and over that heat on spinning drives is the enemy and causes quicker failures. I assume the outer case is dispersing the heat as it should - aka hopefully its not that hot inside as well. Cuz the outside case is very hot to the touch. Is this normal? Does yours heat up this much? Will this cause early drive failure? I have a owc mercury elite pro 5TB and 3TB - both heat up the same. And now that I have Crashplan backing everything up these drives run 24/7 and are getting very hot. If 5 years from now everything is A-OK then I won't worry. But the drives are new and so is my experience with owc drives.
