FWIW, I had the same experience with file servers. Seagate comes last
when I have to order the list of manufacturers from which to buy. 
Western Digital, it depends on the series---but if a disk is bad,
it is bad from the very beginning (unusable on arrival). I had good
experience with Hitachi perhaps because IIRC they inherited IBM
technology, but also more limited experience with their disks
(more difficult to get here depending on the retailers or the size
of the disk).

This above represents just my experience with a limited number of disks
(I'm not Google...).
