So according to sina.com, the average salary in China is 25,000 yuan, which means that they will have to spend half a year's salary on a storage device?

The Chinese love success, they love it, and nothing says I'm successful like a big brand toy. Except maybe a beautiful wife and a beautiful mistress.

As to average salary think - lots of people are living subsistence life styles land to mouth. Whilst other people are living pure consumerist city life styles only seen in places like Tokyo. This toy will be aimed at the second chunk of the population.

30,000py6 for an entry model? With prices like that, you'd think that they think that they're apple.

Conspicuous consumption by the wealthy in China is on fashion, cars and entertainment. Storage devices are pretty much the antithesis of this, and in such purely functional areas the Chinese are exactly that- functional. They're certainly not stupid enough to spend multiples of the going rate for home NAS.
