Query: I promised myself I wouldn't - but I did and now I remember why!

I purchased two of these yesterday to put into a Raid 5 Array and within 10 hrs of use the SMART health went from 98% to 52%. One drive completely stopped working and the other started a very loud clicking noise. Windows server had a warning on it saying it was bad and needed to change immediately. Personally, I've been through 6 different Seagate drives - different models, size, USB, and internal they all failed within a year or sooner. I have WD drives 5 years old that are still going strong with a SMART health in the 80s. I have 4 1TB Samsung spinpoint F3 and only one has failed which was in consistent use for over a year.In conclusion Seagate by far has the most failure rates in HDs I've ever seen and I will never purchase another Seagate again as I live.In other news - I just picked up a WD Black 2TB - it has excellent reliability!!!
