Explanation
Hard drive encryption - specifically hardware-based full-disk encryption (FDE) implemented at the drive level via a self-encrypting drive (SED) or dedicated hardware chip - offloads cryptographic operations from the CPU to dedicated hardware, making it significantly faster than software-based encryption. Software-based encryption consumes general CPU cycles and is slower. IaaS is a cloud service model, and DLP is about preventing data exfiltration, not encryption speed.
