Fast SSD, very small, very light and very fast. The choice in this capacity (512 go) is still limited, and the price (for DSS), not found in other brands. It is the second that I buy to replace a conventional hard disk 1TB, but practicality is undeniable. That said, I do all my files retains more (I do not use it in half, think about your mind preservation), I'm sorting, and it's good like that. For large collectors, wait again, the price should drop quickly. That said, Good material, so good brand.
