The best hard drives??

[Richard Pope]

Paul,
     You are entirely correct when it comes to temperature. Even ten or 
20 degrees F can severely shorten the life of a HDD. It looks like I 
will be getting HGST drives even though I have had some difficulties 
with them.
GOD Bless and Thanks,
rich!

> One caution: I can't point to any manufacturer as "always good" or "always bad".  The reality is that drive design is an incredibly hairy job, and small issues can appear in a given model to mess up the reliability of a particular design.  Sometimes those design issues don't appear until some time after release.

Conversely, if brand Y had a bad implementation of 3 TB drives, that probably doesn't carry over to later models (not even later models in the same size, let alone in different sizes).

> If you run your drives in a well cooled enclosure, that will help.  I've seen some drives that became problematic when run at the high end of their temperature specs, as might happen in high powered servers or in storage arrays with lots of drives in a small enclosure.  Some failure modes are related to temperature, and if your drives are well below the spec limit that will help.
