Why do frame times spike to 45ms during combat in Sword and Fairy 7 on FireCuda 510?

Group battles were causing massive stutters, with frame times jumping from 8ms to 45ms. I suspected the Seagate FireCuda 510 was fighting for I/O resources with background services. I tried disabling the camera in Device Manager, but it killed my stream, which was a frustrating dilemma. I needed a smarter fix. I used GamePP Peripheral Driver Conflict Detector to set Razer Synapse sync to Manual and enabled hardware encoding priority in OBS. RivaTuner showed frame times stabilizing at 7-12ms. HWiNFO confirmed CPU usage at 65-72% and fan speed at 2200-2500 RPM.
