Waveshare PCIe - 2-CH M.2 HAT Compatible with Raspberry Pi 5, M.2 NVMe Solid State Drive Supports 2230 2242 2280 Fast Read/Write

This PCIe two channel M.2 Pi HAT works very well with the RPi 5. It is relatively easy to install even without instructions. It came with all the screws and standoffs needed to mount the device to a RPi 5, including small knurled thumbscrews to hold the NVME drives in place. You do have to be careful when aligning the GPIO pins to the connector on the HAT, but that is true of any HAT you are installing on a Raspberry Pi. Once I figured out a mistake I had made orienting the small PCIe interface cable it came online and I was able to install the two NVME drives I had purchased for my NAS project. This HAT is compatible with the OpenMediaVault NAS software I am using, although that is not a surprise. It should be compatible with almost any software or operating system given that it comes online so easily. The price point is good, too. Overall I am pleased with this purchase.

If you need two NVME drives, this board works very well. I installed 2 nvme's and tested both for speed, here are the results using "dd" command. #"-NVME0 Write Test." #> dd if=/dev/zero of=/home/pinox/xnvme0/xtst bs=500M count=1 oflag=sync 1+0 records in 1+0 records out 524288000 bytes (524 MB, 500 MiB) copied, 2.15291 s, 244 MB/s #"-NVME0 Read Test." #> dd if=/home/pinox/xnvme0/xtst of=/dev/null bs=500M count=1 oflag=sync 1+0 records in 1+0 records out 524288000 bytes (524 MB, 500 MiB) copied, 0.339717 s, 1.5 GB/s . #"-NVME1 Write Test." #> dd if=/dev/zero of=/home/pinox/xnvme1/xtst bs=500M count=1 oflag=sync 1+0 records in 1+0 records out 524288000 bytes (524 MB, 500 MiB) copied, 2.16044 s, 243 MB/s #"-NVME1 Read Test." #> dd if=/home/pinox/xnvme1/xtst of=/dev/null bs=500M count=1 oflag=sync 1+0 records in 1+0 records out 524288000 bytes (524 MB, 500 MiB) copied, 0.414051 s, 1.3 GB/s #"-Copy NVME0 to NVME1 Test." #> dd if=/home/pinox/xnvme0/xtst of=/home/pinox/xnvme1/xtst0to0 bs=500M count=1 oflag=sync 1+0 records in 1+0 records out 524288000 bytes (524 MB, 500 MiB) copied, 2.19423 s, 239 MB/s I hope this helps you in deciding if you want to buy this board.

Le montage est fait, reste à tester le tout

HAT passt und funktioniert wunderbar. Die PCIe SSDs sind zwar etwas dicht beieinander aber das ist ein Problem meiner großen Finger. Ich habe ein Wärmeleitpad und einen schmalen Kühler auf beide Platten gesetzt, so dass es sogar mit diesem Aufbau in ein etwas höheres Gehäuse passt. Jetzt läuft mein Raspberry Pi 5 mit zwei SSDs im RAID1 und btrfs - like a charm!

Questa scheda di espansione per RPi 5 è stata un vero game changer per i miei progetti! L’installazione è stata semplice e immediata, e la compatibilità con il Raspberry Pi 5 è perfetta: nessun problema di riconoscimento, nessun glitch, tutto ha funzionato al primo colpo. Il vero punto forte, però, è la possibilità di installare due moduli di memoria contemporaneamente, con supporto fino a 4 TB per modulo. Una capacità enorme, ideale per progetti che richiedono tanto spazio, come media server, backup locali o applicazioni IoT avanzate. La scheda è anche ben costruita, stabile e affidabile, con un’ottima gestione delle connessioni e delle temperature. Finora non ho riscontrato nessun rallentamento o problema di stabilità.
