 have a couple of secure storage devices these three here so this one here it's USB stick encrypted with a keypad to open it I press the key and then I enter the password one one two two three three four four that's a default one okay and now it is unlocked and I can plug it into a computer and now I can use it so I don't need any drivers on this computer this one is the same but a larger capacity to function button so it has a extra functionality like an administrator pin a user pin you can for example also make things read only device read only and so I have to push the shift key enable it like this then the unlock key one one two two three three four four unlock it's unlocked and I can plug it in and now I can also use that one and then I have this drive here five terabytes it's an hard disk so these two have a built-in battery so that you can unlock them without connecting them here this is different you have to connect it first so that you can unlock it unlock button one one two two three three four four like that and now it is mounted and then I can use it now this advantage of this one is also that after a couple of minutes of inactivity and not using it I think five minutes then it will disconnect but for me up till now that's not an issue because I use this one as a backup device
