@Blacky Wow 5 minutes that’s great. I am using RPI3b+ ethernet that is connected to 1gig switch. My Mac on the same connected switch (as the RPI) speed test gives me D:310Mbps, U344Mbps. Next time I do the update, I’ll monitor my Pi on my Synology Router which will give me device specific realtime speed test result.
@fraintt ok thanks for sharing about your microsd situation, I figured HA will do intensive read/write to microsd that it will wear it down sooner or later. Gladly for my RPI3b+ I found an article that an external HDD can be used via USB, however I am limited to RPI3b+ USB2.0 speeds and 1 gig RAM (not sure how much RAM HA uses for best performance)
Article- How to Boot Up Raspberry Pi 3 from External Hard Disk
When possible I’ll give bootable external USB HD a try and see if it makes a difference.
