A cool drive, is a reliable drive. Basically if your drive gets too hot, it will become corrupt or loose data.Many external drives now come with a built in fan. These cool the disk very well but can make unwanted noise.Some drives are made of highly heat conductive alloys and dispurse heat by simply transfering it into the air.There is a heat sink in contact with the drive which draws the heat to the outer casing where it is cooled by surrounding air.If you dont mind a bit of extra background noise, choose a fan as these are the best cooling method.Some of the more expensive non-fan models are just fine at cooling themselves silently! Others will not last longNow that you have decided on the above three variables
for example.. you may have decidedYou need 1TB for maximum storage capacity of media etc, a FIREWIRE connection bridge and a BUILT IN FANThis would be at the higher end of the price spectrum but will give excellent performance.
You may need only 40GB for backing up word documents etc, a USB connection bridge and NO FANThis would be a budget way to back up files and should still be reliable if the heat sink is effective
