Nope. They really are constructed and/or tested to higher standards. Now, you may have a poor experience putting high-end drives into a crap situation - that's not necessarily the drive's fault.
If you start talking to a company that wants to sell you a lot of drives, and for relatively cheap (a couple of bucks per managed-RAIDed gigabyte), ask them about the duty cycle on the drives. A lot of consumer and even midline drives have duty cycles of less than 40% (put heavy read/write cycles on the disk for less than 40% of the time it is powered up). Enterprise drives are rated up to 100% utilization. If you take a midline drive and an enterprise drive of the same type (SAS, SATA, FC, etc.) and run them at full load head-to-head, statistically, the midline or consumer drives will fail sooner.
