Most reliable external harddrive?

[DudE132]

I plan on getting an External HDD to back up very important things from my PC. What is the most reliable External HDD out there? I want something that can last a long time. Anything 500GB and over would be good for me.

I am currently using Seagate and Western Digital external drives as backup drives. The Seagate drive is in an LaCie enclosure and was purchased from LaCie (have had it for about a year) and the Western Digital drive is several years old. The LaCie drive (ST2000DL 001-9V156 2TB) and Western Digital WD 500AAK 500 GB) are used for backup. I backup all my drives on these two twice a week.

I don't know about reliable, but how about rugged.
