Waveshare PCIe to 2-CH M.2 HAT, Compatible with Raspberry Pi 5, Support M.2 NVMe Solid State Drive 2230 2242 2280, High-Speed Reading/Writing

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.

Easy to install. Worked for me right out of the box.

Very easy to install - Ubuntu recognizes the drives without headaches …

Sleek design and functions as advertised. Unfortunately, it only supports PCIe gen. 2. Feedback I received from Waveshare support indicated that there are no plans for a PCIe gen. 3 refresh of this product.

This is a great product and the shipment was prompt, price was good, and installation easy.

I was disappointed with this product. It was more difficult than necessary to come up with what little documentation there is for this product. There are no clear instructions for attaching it to the Pi 5 or how to properly use the NVMe retaining screws. The design of the board places the NVMe's so close to each other that using many types of NVMe heatsink is impossible. In my case, a board component interfered with one of the NVMe's, causing it to be bent. I have to keep the NVME not fully seated to prevent it being bent. Sadly, there doesn't seem to be any other clear winner for this product category.

I'm using this hat with a Samsung V-NAND SSD 970 EVO Plus 1TB and Hailo AI accelerator. It works great so far. The ribbon cable is a little short; and that makes it a bit tricky to connect. If it were a tiny bit longer, you could connect the cable first and then seat the hat. But as it is, you need to seat the hat first and then connect the cable. And there's not much wiggle room. I actually used a small pair of pliers to gently plug it in. Still, this is pretty much just a pet peeve. Overall, this has been working great, and I would definitely recommend.

Great product, easy to install and automatically recognized nvme ssd and hailo 8l ai chip.

Deux emplacements trop proches: un seul utilisablecz la fois !!!!

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

Ottimo prodotto perfetto per l'utilizzo su Raspberry 4

I picked up the Waveshare PCIe to 2-CH M.2 HAT+ (Type B) for Raspberry Pi 5 to expand storage options, and it’s been a great add-on. The board feels well-made, fits the Pi 5 neatly, and the overall setup looks clean and purposeful once installed. Installation was straightforward as long as you take your time with alignment and mounting. Once fitted, it’s a really convenient way to run M.2 storage on the Pi 5 and makes the whole system feel more “proper” for projects where you want fast, reliable storage compared to microSD. The dual M.2 support is also a big plus for flexibility (storage expansion, separating OS and data, etc., depending on your configuration). A couple of practical notes: make sure you’ve got adequate cooling and case clearance, since adding a HAT can change airflow and height. Also double-check you’re using compatible M.2 drives and the correct configuration for your use case. Overall, this is a solid, well-designed PCIe/M.2 solution for the Raspberry Pi 5—great for anyone building a more serious Pi setup.
