Can hard drives reliably go above 1TB?

I consider Seagate to be the leading brand when it comes to hard drives, back in August 2008 when Seagate was first to roll out 1.5TB hard drives, I was expecting the likes of Western Digital and Samsung to soon follow. To this day (almost 6 months later) the only 1.5TB drive on the market is the very same Seagate drive.

The drive model is ST31500341AS, and if you search for reviews on it, there are very mixed feelings about this drive,  for instance if you look at the reviews here at Dabs.com you’ll see exactly what I mean. Seagate have also revised their 5 year warranty to 3 years to “better reflect current industry standards” Is this because of this very exact drive by any chance?

The fact that every other manufacturer seems 6 months behind Seagate really begs the question, were Seagate too optimistic with the design of this 1.5TB drive? Or did they just rush it out to beat the competition?

I was really looking forward to using this drive back in August, but for now I’m going to stick with 1TB enterprise class drives.
