Hard Drives are pretty durable as long as you don't store them in a super humid 
environment.  Inside and air-conditioned environment, they should last a very 
long time.  The interface, IDE or SATA of various speeds, will be around for a 
long time and like all archival media, you may need to migrate data along with 
progress.

A much more exhaustive analysis here:

Dye layer failure I would suspect.

As for me, I use them, but I only trust them so far and have had them fail with 
5-6 year old data.
