This SSD found their new home in a:
Lenovo Yoga 2 13 33.8 cm (13.3-inch) convertible notebook (Intel Core i5 4200U, 2.6GHz, 8GB RAM, 500GB HDD, Touchscreen, Win 8) silver
The installation was smooth and the SSD is precisely for this laptop. The system HDD, I have mirrored by software on the SSD and then the purpose of saving electricity and noise reduce HDD staked, but left in the computer.
Since then, the computer runs smoothly and without any funny business.
Performance measurements I have not hired - but compared to the installed HDD noticeably faster.
