    So I've got a SSD (get one!) and am loving it. Only thing is I want to encrypt this drive (using Truecrypt). Security concerns aside has anyone noticed a performance decrease after doing a whole disk encryption of a SSD?

    Whole disk encryption has very little appreciable performance impact as the processor can generally handle data faster than the drive can provide it.

    The software that you use for the encryption, does it encrypt the files as they are put on the drive or do you run it and it takes a while to encrypt all the files?

    With whole disk encryption, it abstracts the encryption/decryption to the extent that it's seamless to the user - it does it all on the fly, rather than in bulk.

    I'm just worried it's going to lower the life expectancy of the flash memory.

    Apparently that's not an issue any more.

    Other than the first time, where everything is read, encrypted, and then rewritten, then the file is encrypted before writing, so it still only writes to the drive once, just encrypted instead of unencrypted.
