Just to be clear, I don't think Seagate is doing any worse than any  
other vendor, and (given a small sample size) my WD's have had a  
higher infant mortality rate so far.

The only thing making me chose WD for ZFS is TLDR:

   http://www.google.com/search?q=site%3Awikipedia.org+WDTLER.EXE

since Seagate just came out with a low-power drive.  If somebody can  
show me how to tune a Barracuda like a WD, I'd probably switch back.   
If you can spend the money for an 'enterprise' Seagate this isn't an  
issue for you.

Just the idea of what a hard drive is admits a bad idea (spinning  
rust-coated glass at 5000+ RPM with micrometer tolerances); it's just  
better than the other options right now.

Hard drives fail.  All of them.  We get to bet on when and why, and  
employ things like ZFS to help deal with it.  Even ZFS is helpless  
against small-odds events, though - sooner or later somebody will  
have 3 drives of their raidz2 fail over the same night.
