Both of my external hard drives are Iomega 160 Gigs and they're both on 24/7.  One of them is now my backup drive, the other is my temp drive for unzipping stuff to move around.  Neither one of these has ever failed in over 2 years of constant use and access.  The only reason I moved my external runtimes is because the load time from my SATA drive is much faster.
