[ale] SATA Hard Drive Issues?

[Greg Freemyer]

Yes,

I had a dual drive failure a year and a half ago.  Both drives had
less than a couple hundred hours on them.

About that time, the mdraid mailing list started advising mixing your
raid sets up with drives from different manufactures.

In 2008 and early 2009 there were a bunch of bad drive lots floating
around.  We didn't have any DOAs, but we had maybe 10-20% fail in the
first few hundred operating hours.

The bad part is we did a multi-hour burn-in thinking that would catch
the bad from the factory drives.  None of these drives failed at that
early stage.
