Linux Full Disk Encryption Performance For The AMD Ryzen 7 PRO / HP Dev One

While in pure I/O benchmarks like FIO there is an obvious impact to full disk encryption and other synthetic workloads, across the real-world benchmarks the performance impact of running under full disk encryption tended to be minimal. Unless you are engaging in seriously heavy I/O workloads constantly, the security benefits of full-disk encryption for production systems and especially laptops is highly worthwhile. I'd definitely encourage all users with sensitive data to be using full-disk encryption. I've been using LUKS encryption on all of my production Linux laptops since ~2006 without issue. It's wonderful that Pop!_OS encourages full disk encryption in the default path and would be great if it was actively encouraged by more Linux distributions rather than often being hidden under an advanced install option or manual disk setup.

Across all of the benchmarks conducted, the full disk encryption run had less than 1 Watt higher power consumption for the AMD Ryzen 7 PRO 5850U with HP Dev One. The CPU temperature from the additional encryption work was also minimally impacted.
