“Works as advertised. I love to be able to have a serious storage device on my Pi, and the Pimoroni part is attractively priced, too. The one thing that I would have appreciated is a small piece of paper that explains that the PCIe connector on the NVME board is a "clip" connector that works differently that the "snap" connector on the Raspberry Pi side. I was about to throw the board away when the clip opened, thinking I had ruined the board's connector while trying to open it ;-)”
“This was delivered quickly. Installation was fairly straight forward but the ribbon cable is rather fiddly. Not sure anything can be done to improve this. Also the ribbon cable partly blocks access to the SD card.
Be sure to get one of the drives listed on the Pimoroni website or risk having an incompatible M.2 drive that will not work, that means anything Western Digital I believe. I was previously running from a fast Sandisk ultra fit USB memory stick. The NVME M.2 performance does not seem to be any faster so far but it does free up a USB port. For speed on a budget the Sandisk ultra fit cant be beat, 32Gb for £7.50 but for large capacities NVM-e. I did experience trouble getting the it to boot from the NVM-e, in the end I had to use the Raspberry Pi imager not the SD card copy utility on the Pi to write the OS to the M.2 drive.
The instructions on the Pimoroni website to update the firmware do not seem to work and could do with revising, I could not do this but only people with pre december made Pi 5's need to worry about this.
I used a Crucial P3 Plus 500 Gb drive from ebay at £27.90p , not the fastes but it runs cool. With hindsight the Pimoroni base + 250Gb Drive would have been a good option.”
