Fixing storage link issues for Samsung 9100 PRO 4TB?
It's wild that a drive this fast can turn an old game into a slideshow. The Samsung 9100 PRO 4TB's PCIe 5.0 link was fighting with Battlefield V's legacy IO requests, causing it to flip-flop between Gen 5 and Gen 4, which created 40-60ms spikes. I tried limiting the read/write speeds via software, but the loading times doubled, which was just mental torture. I eventually went into the BIOS and forced the M.2 slot to Gen 4 mode and updated the chipset drivers to clean up the IRQ distribution. In GPU-Z, the link finally locked at 16GT/s, and those erratic frame drops vanished. My boot time slowed down by about 2 seconds initially, but disabling Fast Boot sorted that out. The drive runs hot, between 58-65℃, but the heatsink is doing its job. Exported the system logs and confirmed the link errors are gone, with fans humming steadily at 1400-1600RPM.
