NVIDIA DGX Firmware Bug Throttles NVMe SSDs to USB 2.0 Speeds
superSmitty9999 · reddit · 2026-08-02
A developer reported a major firmware issue with NVIDIA DGX devices where the USB-C NVMe SSD connection randomly disconnects. Upon reconnecting, the transfer speeds severely downgrade to USB 2.0 levels (around 50MB/s). This significantly impacts data transfer efficiency for local AI developers, and the community is currently seeking a fix.
