High Speed SSD Options?

I’ve seen several articles and videos about high-speed M.2 SSD (solid-state drive) hacks for Raspberry Pi 4b which is a compact way of booting and running from a USB external drive mounted on board, and even faster solutions make use of custom carrier boards for the bare-bones Raspberry CM4 module.

Since this is faster read-write speeds faster than a microSD Card, has any research been done on compatibility with the Pisound?

We haven’t heard of anyone using such a setup with Pisound yet, but in theory, it shouldn’t impact compatibility with Pisound at all, as long as the whole system is getting enough power through the power supply. :slight_smile:

There are several kits available and I only got confirmation on the correct kit and specific type of memory I need for this. I will post my progress with assembling but could use some help with optimizing configuration and benchmarking its performance afterwards.


As you know, I have been working on adding high-speed mass storage options to my pisound.
Jeff Geerling recently shared news of Raspberry Pi OS now having built-in SATA support.

I have done this with the MODEP package and a USB audio interface. It works great.

I not done this with a Pisound yet – mine just arrived today. I’ll do an update once I get to setup the card.
