Disk speed test using G-Tech Slim 500MB external 5400. USB3. Formatted as ext4. Connected to USB3 on Pi-4.
Using Blackmagic disk speed test:
9MB/s read and write when Pi-4 is connected via WiFi only [In the U.K., both the Pi3B+ and Pi4 max out at 150Mbps on 5GHz AC WiFi.]
50MB/s read and write when Pi-4 is connected via ethernet. [About 400Mbps - which is what I understand the Airport Extreme puts out via ethernet]
85MB/s read and write when disk is connected directly to Mac.
When I shifted over to Pi I thought I could get away with keeping HFS+ on the external disk connected to the Pi. After numerous inabilities to write to the disk via the Mac, and read permissions issues, reformatting as ext4 has stabilised things.
