This week, Brett is back to talk about self-encrypting hard drives for data encryption. Self-encrypted drives (either HDD or SSD) are drives that encrypt themselves when data is writing to the disk and decrypts the data on the way out. Brett discusses what self-encryped drives are, why are they useful and gives a short demo how to use these drives inside Houston. Also, he talks about the differences between a hardware defined solution for data encryption versus a software defined solution.
