If two USB drives are connected to a Windows notebook, one containing the Tails OS, are there any security loopholes or anonymity breaches by downloading files from .onion sites to the second USB drive? Are there any give-aways during transmission.
How about SD cards instead of USB drives for saving files?
Is the separate USB/SD safer than saving files directly to the notebook's hard drive, whether or not it's encrypted? Is the usage of encrypted USBs or SDs any better?
