Cloud shmoud. I want my sensitive data with me, preferably on my person, available even if there is no internet connection. For this, I use Corsair Survivor.
The device is waterproof and shock-resistant, with aluminum housing.
My device is attached to my keychain. This way, I can always download or save something, or retrieve important documents.
