The stick is quite fast and has massive storage (128GB). However, he did when writing from the outset a few short "dropouts". After 3 weeks, all data were suddenly, after plugging away (almost 70GB). There were only data fragments present, a restoration was unsuccessful. Formatted drive new and returned and requested compensation. After the loss of almost 70 GB data my confidence in the product is not so great that I would again be used.
