Hi, I am visiting a country where the Voltage is 240 Volts & I have collected some data. I want to take that data to a country where the voltage is 110 Volts. What is the best way to carry that data besides backing up on DVDs ? It is over 300 GBs so DVDs is not an answer. How about a Hard Disk ? But should it be an external HDD OR an internal HDD ? OR some other means ? Thank You.
