SSD disks are not reliable?

The news spread like wildfire on the Web. The first generations of SSD drives suffer from a serious problem of reliability. A failure rate of 10 to 20% is very high, or 10 to 20 times more than a conventional hard drive.
It would be nice to find reasons for these problems, they remain unacceptable given the prices. It remains the case whether or not this figure is verified, which is not (yet) the case. But you know, the Internet is a huge sounding board for any problems. Until now, cases of failures of SSD. Of course, sales of these drives are still confidential, but not zero and, for example, no Mac site, to our knowledge has reported a failure of a MacBook Air SSD disk - something that would cause some noise without a doubt.
The article also speaks of another phenomenon, more credible, the returns of SSD disk by users disappointed with of their price vs performance.
This is more understandable. The SSD disks have low reading access times compared to a regular hard disk. It is their biggest advantage. However, the currently marketed products have yet to show blazing speeds. In fact, the difference is felt in some circumstances, but not in others where it may even be negative . The main failing of SSD discs is their much too high price, which raised hopes of wonders and amplifies any disappointments.
