hardware based vs software based

Ever wondered how much overhead does software based encryption creates, see the performance impact benchmarks below:

The Seagate drives have a chip that performs the crypto functions, so there is essentially NO performance impact. Hardware based encryption is awesome! :-)

Yup, there are already several laptop HDDs out there that do FDE, and with hardware based solutions there's virtually no performance degradation since the chip's encryption/decryption bandwidth is an order of magnitude higher than the drive bandwidth.
