Summary: I keep a rolling set of six external hard drives, replacing or upgrading each one over the years. The WD MyBook that houses this one is the only surviving original member, going strong from 2008, that's over 7 years. Not so bad.
Great drives but these are not designed for RAID configuration
The Truth, Amazon
5 December 2014
Summary: Great drives but these are not designed for RAID configuration. One of them died on me after months of serial abuse on my QNAP NAS. I'd say they aren't enterprise strength, but great otherwise.
Summary: Had this thing for 6 years and have been using it constantly since. Started out as a boot drive, then became a storage drive since. It does park the heads (or some method) to save energy, so video games have the occasional 2 seconds frame freeze every 10 minutes or so and movies tend to do it too...
