As much as I was happy buying a G-Tech, I bought my G-Raid was the assumption that one of my other drives would fail like I read about online, every drive I have owned has worked flawlessly, so for me the G-Tech was not really completely worth it.
But everyone has their own experiences, but I imagine that most of them are positive. Sure, there are these threads about how person x's drive failed and person y wouldn't buy anything but them. I own three drives that there are plenty of horror stories about.
No one (except MacDawg) would ever post: "I love my Western Digital 1TB Drive", unless someone posts a horror story about one. Companies ship tons of drives daily, not everyone will be perfect.
The best advice is to find one that has a good warranty and excellent customer service. And then avoid reading these threads so you don't lose any sleep.
Or you could be OCD, anal and paranoid like me and have two back-up drives...
1TB is prbly a good size to start at it, I would say most people looking for non-mobile externals start at that size,
here is a recent thread about that...
More literature found
here.
Here, is
another thread on 1TB Hard Drives
This one is about LaCie...
Here is another, there is some more discussion about LaCie in there...
Here is one on USB 1TB, I'd stick to Firewire...
