Understood.
However, I was able to get mine with the four 2TB drives for under $600. Where did you get that pricing?
I use it for backing up all my music, movies, and 5 computers. It is built like a tank and I love it. However, I can understand the price issue. It took my about 5 years and 3 failed "lower-end" NAS devices to make me jump to a higher end consumer product. I would have loved to jump into a rack mounted NAS, but $2K was too much right now. Maybe some day.
While I do wish reliability, its purpose at the end of the day is to hold my movies, nothing more.
