It depends upon the drive. Some manufacturers' drives run hotter than others. On my system, my 2TB WD green drives run about 10C cooler than my 320GB Seagate system drive. They are all healthy, at least according to the SMART interface data that I monitor. That said, I have had Seagate 500GB-2TB drives that ran too hot and failed sooner than they should have. Fortunately, most were under warranty, so I only had to pay for shipping in a couple of cases. The replacements are still running hot, so I have decided to use 7200rpm WD drives for now. They have been much more reliable, have fewer bad sectors, and don't overheat.
As for noises when you copy files, that is probably the head positioning drivers. They do make noise to some extent - which is why I usually stream some music when I am running my system (like right now)... :-)
FWIW, Hitachi has a good reputation, and as a disclaimer, I used to consult with Seagate. I still prefer Western Digital drives.
Yes wd drives are more reliable, unfortunally i cant found the 1tb (black version) in my city (casablanca, morocco) . Anyway i sold that pieace
shit (hitachi) to a friend of mine that is going to run it on a dvr , i also lost an external 60 gb hitachi drive this week . Looks like im going to move to seagate drives again ...
Thank you Rubberman .
Well, if the Hitachi is otherwise working ok, I wouldn't worry too much about the current temperature. Just make sure the drive gets enough cool air flow over it - escpecially the controller circuitry on the drive.
