I recommend fans (active cooling) for the hard disks:
- Most Off-the-shelf External USB 3.5" Hard Drives (except possibly: Apricorn, which has a fan, and 2.5" drives) may die from heat after a 3-hour backup session because they have no fan. special fan-cooled cases are available though.
- NAS with fan for the hard drives. It seems drives the size of 500GB or larger in an enclosed box get extremely hot (>170°). This can cause drive failure (happened to someone's Maxtor: external USB hd box, no airholes). commercial electronic components (chips) are rated to only work at absolute maximum 85°C(185°F)! Terabyte drives get even hotter because they have more platters to spin: hitachi 1TB drive is described as "hot, fast, and loud". Some drives like the seagate Terabyte drives run cooler though.
heat can also be the cause of stiction, where on certain mfrs of drives the lubricant on the platter becomes like glue due to the heat and when the head rests on the platter and cools down, it's stuck and the drive won't spin. heat can also cause damage to the electronics. hence...

anything other than their low-end products. their low-end products noticeably have no fan!
it seems all they make is NAS products. And they look nice.
