I am very satisfied with this product. Certainly, the price is therefore to Go but windows occupying "only" 40 GB with my few basic programs it leaves room. For the rest I go through an external HDD or USB flash drive. And performance are the appointment. Starting and extinguishing the PC record time, no more lags, web pages open instantly, as we gain in autonomy ... For installation I simply did drive the exchange then booted dvd created during the acquisition of the PC. Cétait really long but I recommend it to all those who must do housework on their PC and enjoy resettlement to move to SSD. Appraisal: Note max 7.9 to Windows test (seven 64) and it shows. Next up my PC (tower).
