In ten years, across several different machines, different companies, and different operating systems I've noticed a trend that external hard drives die long before their internal counterparts. Everyone I've spoken to who has used external hard drives for any period of time has shared the same experience.
At first I thought it was because they are moved a lot more than internal drives, but my laptop internal hard drives seem to last as long as my desktop ones, and I've had the same short lifespan when external drives are never moved.
Is this a known issue? Do external hard drives have substantially shorter lifespans than internal drives? If so, what can be done?
