Heres what I have found, every company has a bad batch, and every company will always make some customers unhappy. Some like WD and not Seagate, and others the exact opposite. The fact is that all drives will crash at one point, and sometimes they can crash at random times, for ALL companies, not just some.
In my experiences, Western Digitals have lasted a while, along with Seagates. However, Hitachis didn't last as long. So I would suggest a WD or Seagate. My personal preference is WD, but everyone has different opinions.
If you are getting drives just for backup, go for WD Caviar Green or Seagate 5900 RPM drive. They run slower, but use less energy and don't get as hot. Otherwise, I would suggest a normal Seagate 7200 RPM drive or WD Caviar Black.
