  • Bitlocker vs Embassy Wave w/ Encrypted Drive?

    Hello All,
    We have many, many Dell laptops out there with the hardware encrypted drives that use Embassy Wave software and a TPM chip to secure them.

    Windows 7 has (now easy to implement!) bitlocker and it doesn't require the hardware encrypted to drives to operate. The cost of more expensive windows is a wash if I don't have to pay for more expensive drives.

    Does anyone know what sort of performance hit I might be taking with bitlocker encryption instead of the other solution? I could probably do some benchmarking myself if I had a reliable utility to use.

    Thanks for any help.
