Thanks for doing this! > Cons: > 1) Buffered Read and Buffered Transfer Rate was almost halved after > TrueCrypt FDE was enabled :-(. Yes, to almost the exact same rate as sequential reads. I'm guessing it simply doesn't implement look-ahead decryption. It might even be a positively good idea to not decrypt anything until you're specifically asked. > 3) The initial encryption of the 120 GB HDD took 2 hours. You think a 1GB/min encryption rate is so slow as to count as a "con"? I think that's fairly reasonable. My lightly loaded AMD64x2 box just took 48s to copy a 584MB file from one place to another on a first trial, and between 26s and 39s on 'hot' retests. Or are you suggesting that it could encrypt each block OTF when it's first accessed, or run the encryption in the background while the system was still live, instead of converting the whole drive in one big bite? cheers, DaveK -- Can't think of a witty .sigline today.... --------------------------------------------------------------------- The Cryptography Mailing List Unsubscribe by sending "unsubscribe cryptography" to [EMAIL PROTECTED]
