A user on Reddit shared findings on optimizing AI image generation speed by strategically placing model components on different storage types. They discovered that moving the text encoder, specifically the Qwen 3 VL model, from a SATA SSD to a Gen 4 NVMe SSD significantly reduced image generation time from 70 seconds to 40 seconds. In contrast, relocating the diffusion model (UNet) to the NVMe drive had a negligible impact on performance. The user recommends prioritizing NVMe storage for text encoders due to their frequent disk access during prompt changes, especially in low VRAM configurations, while larger diffusion models can remain on SATA SSDs.
