Transparent Database Encryption TDE performance on SQL 2008 RRS feed

  • Question

  • Does anyone know what benchmarks exist for the different algorithm options for setting up TDE. i.e.
    WITH ALGORITHM = { AES_128 | AES_192 | AES_256 | TRIPLE_DES_3KEY }

    What sort of hardware compensation is needed for AES_128 vs AES_256. Is it truly a two fold difference in performance hit?
