Correct, you use the SD card only to start up the Pi4, and point to the SSD, but the entire system files are on the SSD, so any system file swapping and file downloads now goes through USB3 and the SSD, not through the SD card bottleneck. MUCH faster, plus you can now also use a swap file on the SSD. I need that on occasion when using FITS viewer at high magnification during the run to inspect the quality of my guiding. That can max out your memory and crash the machine otherwise.

This explains my crashes as I have been doing the same thing, inspecting the subs by zooming in and often it would stall for up to one minute and recover or Kstars simply crashes.
