The Google 2007 paper "Failure Trends in a Large Disk Drive
Population" ( basically
laid to rest the myth that there's any significant difference between
drives or makers, and I don't think anything substantial has changed
since. The current price/capacity sweet spot then becomes the focus, and
last I checked that was 3TB 7200rpm.

There have been issues with near-simultaneous failure of many drives
from one manufacturer, though -- the massive failure of Fujitsu drives
manufactured in 2000-2001 with Cirrus Logic chips encapsulated in faulty
plastic being the most infamous example
( Ever since I got bit by that, I've tried to mix drives from different manufacturers in arrays, but it's a real chore to source enough different types of drives with close enough specs, and I've sometimes had to cave.
