General discussion • Re: Booteable NVMe on RPi Zero 2W?

Can you recommend one that is known to work?

Orico USB 3.1 Gen 2 Type-C M.2 NVMe SSD enclosure M2PV-C3
The M2PV-C3 enclosure uses the Realtek RTL9210 chip for the USB interface. The chip works reliably as it is tested to the higher standard of USB 3.1 instead of the low USB 3 standard.

Raspberry Pi Zero 2 as a boot disk through the USB 2 interface:
Sequential write speed 29332 KB/sec (target 10000) – PASS
Sequential read speed 33586 KB/sec (target 10000) – PASS
Random write speed 3441 IOPS (target 500) – PASS
Random read speed 2771 IOPS (target 1500) – PASS

For the Pi, I use NVMe SSDs left over from upgrades to other machines. The USB 3.1 interface means I can plug the device into my Pi 5 or Intel notebook for maximum read and write speeds when testing or backing up.

Pi 4:
Sequential write speed 318522 KB/sec (target 10000) - PASS
Sequential read speed 373424 KB/sec (target 10000) - PASS
Random write speed 24317 IOPS (A2 target 2000) - PASS
Random read speed 29388 IOPS (A2 target 4000) - PASS
Pi 5 (My development machine):
Sequential write speed 344020 KB/sec (target 10000) - PASS
Sequential read speed 381577 KB/sec (target 10000) - PASS
Random write speed 34675 IOPS (A2 target 2000) - PASS
Random read speed 33149 IOPS (A2 target 4000) - PASS
