How is the Pi 4?

I’ve moved my boot and file system from an SD card to an inexpensive USB SSD, which really speeds performance.  The sole problem with a true standalone Pi for music is file storage, and you’re potentially compromising performance/ SQ if you use USB for both file storage and output to your DAC.  The solutions (beyond network storage, which is the best way to go IMO)require using a separate bus for file access and include a DAC in a HAT, a WiFi DAC, a WiFi HD etc.  The 4 has separate buses for network connections and USB, unlike the older Pis - so WiFi activity does not share a pipe with USB traffic.

 

Linux typically loads the OS from SD into memory and then doesn't access the SD card much when its running perhaps except to write to log files. Best not to use the USB bus for double duty (file access and DAC output).
