The rate is satisfactory, but nothing stunning on smaller files, which remain the stumbling block of all storage media whatsoever. I was very interested by the integrated encryption software, but I just get rid of it because: - It disrupts my wireless mouse that becomes uncontrollable (Logitech M215) - It crashes in the middle of a file copy
No question of risking not play my files when the day came, so I prefer storing unencrypted.
