Well, after my HDD hard drive was smoked in the laptop, needed a SSD. 10 years (Samsung) guarantee ... that's an announcement !!! The technology is still expensive arg (would rather have the 500 GB version purchased), but who attaches importance to a stable hard drive, can not avoid SSD. In the relevant magazines and online portals extensive (comparative) are tests available to this SSD and can be read (because it takes me not to do so). Important seems to me the information that my laptop S * ATA2 (2.5 ") support and installation absolutely smooth handover.
