N16 Quad M.2 M-Key NVMe SSD Peripheral Board for Raspberry Pi 5, Support M.2 NVMe M-key 2230/2242/2260/2280 SSDs

I used this NVMe storage HAT to build a personal NAS project, and after some hands-on use, I can confidently say it’s a great piece of hardware. It’s performed reliably and efficiently, making it a solid choice for anyone looking to create a compact and high-speed NVMe-based storage setup

This board has serious reliability issues with controller resets.After i encoutered them i found multiple cases of the same issue online, including customers receiving a replacement & still encountering the same issue. This item should be removed from sale or the 2 drive write limitation clearly documented. neeldless to say, had i known of these issues, i would not have ordered it.details..when 3 or 4 drivers are written to at the same time, random controller resets occur. This causes writes to fail at best and damage to the array or complete file system failure at worst.Raid configurations of 3 drivers or more drives are just unreliable, but standalone drives written to individually seem to be fine.i have tried multiple RPI's, multiple PSU's (offical RPI 5A & 100W PD, to name a few). multiple FPC cables, my own USBC PD uplink cable & multiple brands/size of NVME. I even tried throttling data uploads at the client to reduce load on the pcie switch, but in all cases the random controller resets still occur after some period of writing data to 3 or 4 drives at the same time.in conclusion, this product is not fit for the advertised purpose & will be returned.

There are some bad reviews but this works as described for me, I use a PD100W power supply & have a small fan pointed at the enclosure, 4x 2TB NVME Drives, Openmediavolt & Share using SMB, drives mounted in windows. I have downloaded 1000's of .Rar (1-2GB) and extracted while transfering files between drives. No errors or disconnected It does what its meant to do. I dont use raid so I cant comment on that.

Nice for a small NAS

Bought this a while ago to build a media centre, I've finaly gotten around to making it, 4 X 4tb and 2 x 2tb NVME drives, should have enough space!

Just the right choice for my project to develop a multi-boot Raspberry Pi 5 SBC server with multi-boot functionality.

The board + case option with the PCB style USB-C power connector between the board and the Pi 5 has a serious known fault where if more then two M.2a drives are used at once the controller suffers power dropouts and resets. If you fill 4 nvme slots and try to use raid 5, for example, it will fail after 10 seconds or so, and take 30 seconds to come back on line. Using each drive independently is Ok for a while, but again if 3 or 4 drives are accessed at once it will reset.Apparently - won't know til I get the replacement - the newer board with the cable power connector increases the voltage to overcome this, at the expense of increasing the heat of the nvme drives.

The metal case seems really well made. There are no sharp edges, and it slots together very easily.As for the riser board and the cooler, both seemed to work well. Takes a bit of work to get the pci-e connection to work, but all the instructions are included in paper, or you can go to the wiki website noted with it.I connected a couple SSD's to it, set up RAID, and then connected it up and I was able to access them as expected. Was all pretty easy tbh and now I have it running in the background all the time so will see how it lasts.
