This key has a reasonable price, bought 14 March 2014 (1 year). No technical problems since its purchase. The average rate on 1GB files 100MB is goshawks of 4mb / s. What I find slow.
Now she serves me every week for 1 year on big and small files without incident while I often hear people around me complaining about the untimely death of their keys. Kingston remains a reference for backups and transfers.
