How about new drives?  Or drives that aren't more than 2 or 3 years old?

Seagates are OK, Fujitsus are better.  The less use the drive has gotten 
(assuming some use, I'm not sure I'd trust a NOS 5-year old drive any 
more than a heavily-used 5-year old drive), the better.  By that I 
don't mean just time spent spinning, but less accesses to the drive (a 
drive that used to be an OS drive on a machine would be preferable to 
one that was used to hold a database or mail spool).
