Fast File Encryption for Windows?

cryptoz wonders: "I've used numerous encryption applications for both Windows and Linux over the past few years and have always been satisfied. Until I realized I needed to start encrypting large files (say 10 to 30 GiB), or at least a large number of small(er) files. I found that everything I use seems to take hours and hours to compress, encrypt and shred. Not to mention decompressing, decrypting and deleting on the other end. Every web search I do on the topic seems to turn up mostly closed-source applications or snake oil, neither of which is acceptable. Does Slashdot have any suggestions for fast file encryption? I should make it clear that in my particular case, I do not need to have a perfect key or incredibly secure encryption, since it is not the weakest link (as I am susceptible to hardware key-loggers, CRT eavesdropping and the like). The encryption needs to be just strong enough, but most importantly, *fast*." This is a worthwhile question, but when dealing with files in the 10s of GB, can anything really be considered to be "fast"?

Hardware acceleration.

I suggest getting some hardware acceleration: the VIA EPIA boards use electrical interference in their traces to suppy entropy to a hardware encrypt/decrypt enginge that can achieve 25 Gb/s encryption. This is a 1.0GHz passively-cooled board with SATA ports, hardware MPEG2 decoding and all on a 17x17 cm^2 board.

How I am to know that 10 years from now my archived files won't be permanently lost because the closed-source SureCrypt no longer runs on the then-current Windows? This is one of several reasons I wouldn't touch a closed-source encryption program with a 10-foot pole. (Other reasons include no assurance of encryption strength and no assurance that there isn't a backdoor key. Plus it won't run on Linux, and afaik has no command-line interface for scripting even on Windows.)
