How secure are these drives? Are they easy to crack? I have a few bank accounts and unique details, software scripts and IP I need to save. Don't want it sat on my HDD but don't use it often. Are the 256 AES drives secure. Here is the product I had in mind

If you are that concerned, you could look at products like these:
