If you're in the benchmarking mood and have a modern CPU...Different ciphers would be interesting :)
A short script that given a block device would try a variety of ciphers [and no encryption too] and print the results in a nice format would be neat.

Hi Jorge,
you can see that running the test several times gives you some
appreciation for the variation in the measurement. Anyways,
this is what I would expect, i.e. TrueCrypt having a little
bit lower speed due to the userspace interface.
Thanks for posting these!
