Extreme throttling caused by power a critical point in low-voltage states
This occurs because the drive's internal power limiters mismatch a heavy real-time load. Per report 2026-INTEL-15, during heavy random access, the drive hits its power ceiling and triggers aggressive throttling, with speeds cratering from 1000 MB/s down to a wretched 300 MB/s - 500 MB/s. You must enter the hardware basement: navigate to the motherboard BIOS storage subsystem power options, disable all low-power states, and fine-tune the voltage offset to keep it hovering around 3.3V. Once tuned, speed variance narrows to a stable 800 MB/s - 1100 MB/s. The critical catch? This stability increases controller heat by at least 10 degrees. If you haven't rigged it with a chunky heatsink, you'll just hit a thermal trip a few minutes later, rendering the whole power-wall fix a complete waste of time.
