I ordered the SSD to make my laptop a little faster, especially at the start. The SSD unfortunately I had to order 2 times. The first time the Amazon Warehouse deal. Two days she works fine, but then the laptop has suspended and the SSD was no longer >> SSD dead recognized. Did they easily returned and bought a new one. This works since then without any problems and came up with the latest firmware. Only the installation was a bit annoying, so only 4 stars. Although Crucial has learned and packed with 2 screws in the box, but funnily enough they do not fit in the holder provided for my Lenovo Y560. In order to find suitable screws I had a PC shop, there with 2 very small screws of a full suppression ended CD / DVD Laufweks has helped me. The 64Gb rich all times for Windows 7 and a number of important, frequently used programs. The startup now takes about 20 seconds, much faster than without SSD. The SSD can I recommend anyone who wants to spice up his laptop and do not want to give up its internal hard drive, because this SSD takes the mSATA slot, a separate slot in the laptop case!
