Not to be out done, but in the USA on Amazon.com you can get a frankly incredible 128GB or even a 256GB version of Super Talents Super Crypt USB 3.0 series flash drives.
These are the ultimate replacement to portable hard drives. They have the speed of an SSD, huge space and most importantly built in encryption.
Check below for the different versions of this amazing series of USB 3.0 drives.
They are slightly bigger than most USB drives, but with that kind of space and write speeds of up to 180MB/s you can forgive them. Anyhow, compared to your portable hard drive it is tiny!
