I haven't kept up with the Stratux architecture recently, but the latest RPi model (5) has a PCIe connection, so you can actually install a SSD (via a M2 hat) and boot directly from that, rather that relying on a SD card. I'm tinkering with a RPi5 with some AI image detection stuff and they mention that the constant read/write rate inherent with real-time AI evaluation is hard on SD cards and that going the SSD route is more long-term stable. It'll be interesting to see if Stratux goes that way in the future.
ETA: Too bad 6PC is an airline guy and doesn't understand all this technical IT talk anymore...
