Software-based encryption uses the computer's program to encrypt data and Software encryption often uses the user's password as the encryption key that scrambles the data. The encrypted data is secure, only as safe as your computer.
If hackers can get malicious code onto the computer, they can change or disable the encryption, allowing the disk to store unsecured data.
Hardware-based encryption uses a dedicated processor physically located on the encrypted drive instead of the computer's processor. This encryption processor also often contains a random number generator to generate an encryption key, which the user's password will unlock. Hardware-based encryption runs independently of the operating system so it is not exposed to the most common attacks.
