Great product. No luck, as it is a discontinued model I had a refurbished item. No luck, the wise guy who bought it before I had (visibly) glued a label "512 Gb" on a 128 Gb SSD of the same brand. Return the product (5 stars Service Amazon on this point) and no replacement for more stock. So mistrust on discontinued items. The MX200, current range, is a great product that I recommend 110%. So a star for this particular purchase.
