Geekworm X1004 PCIe to Dual M.2 HAT NVMe 2280 SSD PCIe Peripheral Board for Raspberry Pi 5

this item meet the requirement and exceed expectations. we plan to by several more for our projects.

Was worried about the 1 star review but bit the bullet seeing this was affordable enough for my basic NAS setup. It works as expected! My OMV was able to read my NVMe drive. Instructions were clear for the most part.They give an extra ribbon cable in case you break the first one. Fan and case are not included. I bought them separately.Would recommend.

I'm building a Raspberry pi 5 NAS. I currently have a single slot populated with an HP FX900 Pro 2TB, and it seems to work just fine.It benchmarks between 700MB/s and 1000MB/s (read and write) with PCIe gen 3 enabled in raspi-config. That's really slow for what the disk can do, but really fast for an embedded computer, and plenty fast for serving files on a gigabit network.I haven't tested with both slots populated yet, but I'd expect bandwidth to be shared across both disks. I also haven't tested booting from PCIe yet. When I get my second disk I'll update the review.I'm using it with the official raspberry pi 5 cooler, and that fits nicely underneath. I think the solid GPIO connector blocks airflow a little, but only on one side, and cooling performance doesn't seem to be impacted. And it doesn't connect with pogo pins like some other manufacturer's nvme boards do, so it's not going to fail because a pogo pin broke, vibrated out, or got stuck.Additionally, the area underneath the disks is clear. Some other designs have connectors or chips there which prevent some disks, especially double-sided disks, from fitting correctly.And, it comes with all the standoffs and screws needed to attach the board to the Pi.My only complaint is that it includes an unshielded FFC ribbon cable. PCIe is a high speed bus, and unshielded cables are more susceptible to EMI. In data storage in particular, you definitely want signal integrity between the host and the disk. Having said that, it seems to be working. But my use case is for long term data storage, so I'm going to replace it with a shielded cable, and use a filesystem with checksums.Overall it's pretty good.

It's easy to assemble and fits perfectly fineI like that it has the GPIO pins

This doesn't seem to run fast hdparm shows a speed of 413.26 MB/sec

Cumple su propósito

All in all, it works well as described. Just be aware that 2280 is the only size it will fit. The open bay under one and the height of the other may not support a thermal pad (if needed). It's an ok option, with a few good choices.
