SSD not more effective than a hard drive! Stay away!

Until then I did not understand what the problem was in my setup to get rates as bad with this Kingston V300 Now there a few weeks ago the pot with pink and unveiled by the computer press Kingston has changed the components that fit this SSD to put much less efficient without warning staggered or change the product number !!!! As a result, instead of getting speeds of around 450 mb / s read and 350 mb / s write, I end up with 160 mb / s and 90 mb / s. IS THE SPEED OF A HARD !!!!! There is therefore no problem in my configuration, this SSD is no longer complies with the published specifications. In short a scam! For me explain what's the point of buying an SSD over 10x more expensive than a traditional hard drive capacity equal if it is to end up with the same performance? Move on! Do not buy this SSD!

Edit: A big thank you to Amazon to me over and this SSD and it paid well after the period of one month. Very satisfied with the quality of customer service Amazon! Congratulations! Otherwise I still awaiting a response to Kingston your posts Who I think will never come! Distressing!
Otherwise the latest news, according to Tom's Hardware, Kingston no longer commercialize the bad asynchronous memory V300 model among 120 and 240 GB. They have also downgraded the V300 SSD Comparative their Enough said! (Source: [...])
In short, now if you buy a V300, it is necessary that you are aware that you buy the worst performing SSD market light years other SSDs currently on the market! In terms of performance it is similar to SSD there are more than 5 years !!! Both say the prehistoric computer
