What is the difference between Self-encrypting drive (SED) and full disk encryption (FDE)?
1) SED provides hardware-based encryption, while FDE uses software-based encryption
2) SED encrypts individual files, while FDE encrypts the entire disk
3) SED requires a separate encryption key, while FDE uses the user's login credentials as the encryption key
4) SED is only available for certain operating systems, while FDE is available for all operating systems
